AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
The Algorand Vulnerability Scanner provides a structured framework for auditing Algorand smart contracts. It focuses on 11 critical vulnerability patterns specific to the Algorand transaction model, such as rekeying attacks, unchecked fees, and access control issues. The skill enforces a rigorous reporting process, requiring a comprehensive coverage table for every audit to ensure that no security pattern is overlooked, regardless of whether a vulnerability is found.
What it does
- Scans TEAL and PyTeal source code for 11 common Algorand-specific security vulnerabilities.
- Generates a mandatory 11-point coverage table to ensure thorough audit documentation.
- Integrates with Tealer for automated static analysis of smart contracts.
- Provides detailed vulnerability reports including severity, location, and remediation code.
- Offers a structured checklist for manual security sweeps of transaction fields and group logic.
- Enforces explicit justification for why any specific vulnerability pattern might be considered not applicable.
When to use it
- During the security review phase of an Algorand project development lifecycle.
- When performing a pre-audit security assessment of stateful applications or smart signatures.
- To validate the effectiveness of security fixes for previously reported vulnerabilities.
- When training development teams on secure Algorand coding patterns.
Advantages
- Prevents 'silent' audits by requiring a full 11-point coverage report.
- Standardizes the reporting format for Algorand security findings.
- Combines automated tool output with manual verification steps.
- Reduces human error by providing a clear checklist for transaction field validation.
Usage examples
- “Audit my Algorand smart contract in approval.py for security vulnerabilities.”
- The agent will scan the file, run Tealer if available, and produce a report containing the 11-point coverage table and any identified vulnerabilities with remediation steps.
- “Check my TEAL contract for rekeying and access control issues.”
- The agent will perform a targeted review of the provided TEAL code, specifically focusing on rekeying and access control patterns, and report findings in the standard template.

Algorand Vulnerability Scanner
1. Purpose
Systematically scan Algorand smart contracts (TEAL and PyTeal) for platform-specific security vulnerabilities documented in Trail of Bits' "Not So Smart Contracts" database. This skill encodes 11 critical vulnerability patterns unique to Algorand's transaction model.
2. When to Use This Skill
Auditing Algorand smart contracts (stateful applications or smart signatures)
Reviewing TEAL assembly or PyTeal code
Pre-audit security assessment of Algorand projects
Validating fixes for reported Algorand vulnerabilities
Training team on Algorand-specific security patterns

Installation:
uv tool install tealer(ensure uv's tool bin dir is on PATH)Usage:
tealer contract.teal --detect all
4. How This Skill Works
When invoked, I will:
Search your codebase for TEAL/PyTeal files
Analyze each file for the 11 vulnerability patterns
Report findings with file references and severity, above them a coverage table carrying a verdict for every pattern
Provide fixes for each identified issue
Run Tealer (if installed) for automated detection
5. Example Output
When vulnerabilities are found, you'll get a report like this:
=== ALGORAND VULNERABILITY SCAN RESULTS ===
Project: my-algorand-dapp
Files Scanned: 3 (.teal, .py)
Vulnerabilities Found: 2
Coverage: 11/11 patterns reported
1 Rekeying Attack ................... found approval.py:45
2 Unchecked Transaction Fee ......... n/a stateful app, fees paid by sender
3 Closing Account ................... clear Assert(Txn.close_remainder_to() == Global.zero_address())
... one row per pattern, all 11 present ...
---
[CRITICAL] Rekeying Attack
File: contracts/approval.py:45
Pattern: Missing RekeyTo validation
Code:
If(Txn.type_enum() == TxnType.Payment,
Seq([
# Missing: Assert(Txn.rekey_to() == Global.zero_address())
App.globalPut(Bytes("balance"), balance + Txn.amount()),
Approve()
])
)
Issue: The contract doesn't validate the RekeyTo field, allowing attackers
to change account authorization and bypass restrictions.6. Vulnerability Patterns (11 Patterns)
I check for 11 critical vulnerability patterns unique to Algorand. For detailed detection patterns, code examples, mitigations, and testing strategies, see VULNERABILITY_PATTERNS.md.
Pattern Summary:
Rekeying Attack ⚠️ CRITICAL - Unchecked RekeyTo field
Unchecked Transaction Fee ⚠️ HIGH - Fee not validated in smart signatures
Closing Account (CloseRemainderTo) ⚠️ CRITICAL - Unchecked CloseRemainderTo drains the account
Closing Asset (AssetCloseTo) ⚠️ CRITICAL - Unchecked AssetCloseTo drains the asset holding
Group Size Check ⚠️ HIGH - No
Global.group_size()validation on atomic groupsTime-Based Replay Attack ⚠️ MEDIUM - No lease or round-range bound
Access Controls ⚠️ CRITICAL - Update/delete and privileged calls unprotected
Asset ID Verification ⚠️ HIGH - Asset ID not validated in asset operations
Denial of Service (Asset Opt-In) ⚠️ MEDIUM - Push transfers strand on un-opted accounts
Inner Transaction Fee ⚠️ MEDIUM - Inner fee not explicitly set to 0
Clear State Transaction ⚠️ HIGH - Clear state program cannot reject, state left inconsistent
For complete vulnerability patterns with code examples, see VULNERABILITY_PATTERNS.md.
7. Scanning Workflow
Step 1: Platform Identification
Confirm file extensions (
.teal,.py)Identify framework (PyTeal, Beaker, pure TEAL)
Determine contract type (stateful application vs smart signature)
Locate approval and clear state programs
Step 2: Static Analysis with Tealer
# Run Tealer on contract
tealer contract.teal --detect all
# Or specific detectors
tealer contract.teal --detect unprotected-rekey,group-size-check,update-application-checkStep 3: Manual Vulnerability Sweep
For each of the 11 vulnerabilities above:
Search for relevant transaction field usage
Verify validation logic exists
Check for bypass conditions
Validate inner transaction handling
Step 4: Transaction Field Validation Matrix
Create checklist for all transaction types used:
Payment Transactions:
[ ] RekeyTo validated
[ ] CloseRemainderTo validated
[ ] Fee validated (if smart signature)
Asset Transfers:
[ ] Asset ID validated
[ ] AssetCloseTo validated
[ ] RekeyTo validated
Application Calls:
[ ] OnComplete validated
[ ] Access controls enforced
[ ] Group size validated
Inner Transactions:
[ ] Fee explicitly set to 0
[ ] RekeyTo not user-controlled (Teal v6+)
[ ] All fields validated
Step 5: Group Transaction Analysis
For atomic transaction groups:
Validate
Global.group_size()checksReview absolute vs relative indexing
Check for replay protection (Lease field)
Verify OnComplete fields for ApplicationCalls in group
Step 6: Access Control Review
[ ] Creator/admin privileges properly enforced
[ ] Update/delete operations protected
[ ] Sensitive functions have authorization checks
8. Reporting Format
Coverage Table
Report on every pattern in §6, whether or not it turned anything up. Emit this table above the findings, with all 11 rows present:
| # | Pattern | Verdict | Evidence |
|---|---|---|---|
| 1 | Rekeying Attack | found | approval.py:45 -- no Txn.rekey_to() assertion on the payment branch |
| 2 | Unchecked Transaction Fee | ||
| 3 | Closing Account (CloseRemainderTo) | ||
| 4 | Closing Asset (AssetCloseTo) | ||
| 5 | Group Size Check | ||
| 6 | Time-Based Replay Attack | ||
| 7 | Access Controls | ||
| 8 | Asset ID Verification | ||
| 9 | Denial of Service (Asset Opt-In) | ||
| 10 | Inner Transaction Fee | ||
| 11 | Clear State Transaction |
Each verdict is one of:
found— citefile:lineand write the finding up in full below.clear— the pattern applies to this contract and the contract handles it. Name the field, opcode, or check you searched for, so a reader can repeat the search.n/a— the pattern cannot apply here. Give the reason in one clause ("no inner transactions in this contract"). Not having looked is notn/a.
A table with fewer than 11 rows is an incomplete scan and must be reported as one. A row whose Verdict cell is empty is incomplete in the same way: row 1 above is filled in to show the shape, and every row is filled in the same way before the report is done. Eleven clear verdicts is
a result a reader can act on. A report that covers four patterns and says nothing about the other seven reads
exactly like a clean contract, and that is the failure this table exists to prevent.
Finding Template
## [SEVERITY] Vulnerability Name (e.g., Missing RekeyTo Validation)
**Location**: `contract.teal:45-50` or `approval_program.py:withdraw()`
**Description**:
The contract approves payment transactions without validating the RekeyTo field, allowing an attacker to rekey the account and bypass future authorization checks.
**Vulnerable Code**:
```python
# approval_program.py, line 45
If(Txn.type_enum() == TxnType.Payment,
Approve() # Missing RekeyTo check
)
```
**Attack Scenario**:
1. Attacker submits payment transaction with RekeyTo set to attacker's address
2. Contract approves transaction without checking RekeyTo
3. Account authorization is rekeyed to attacker
4. Attacker gains full control of account
**Recommendation**:
Add explicit validation of the RekeyTo field:
```python
If(And(
Txn.type_enum() == TxnType.Payment,
Txn.rekey_to() == Global.zero_address()
), Approve(), Reject())
```
**References**:

- Tealer detector: `unprotected-rekey`9. Priority Guidelines
Critical (Immediate Fix Required)
Rekeying attacks
CloseRemainderTo / AssetCloseTo issues
Access control bypasses
High (Fix Before Deployment)
Unchecked transaction fees
Asset ID validation issues
Group size validation
Clear state transaction checks
Medium (Address in Audit)
Inner transaction fee issues
Time-based replay attacks
DoS via asset opt-in
10. Testing Recommendations
Unit Tests Required
Test each vulnerability scenario with PoC exploit
Verify fixes prevent exploitation
Test edge cases (group size = 0, empty addresses, etc.)
Tealer Integration
# Add to CI/CD pipeline
tealer approval.teal --detect all --json > tealer-report.json
# Fail build on critical findings
tealer approval.teal --detect all --fail-on critical,highScenario Testing
Submit transactions with all critical fields manipulated
Test atomic groups with unexpected sizes
Attempt access control bypasses
Verify inner transaction fee handling

12. Quick Reference Checklist
Before completing Algorand audit, verify ALL items checked:
[ ] RekeyTo validated in all transaction types
[ ] CloseRemainderTo validated in payment transactions
[ ] AssetCloseTo validated in asset transfers
[ ] Transaction fees validated (smart signatures)
[ ] Group size validated for atomic transactions
[ ] Lease field used for replay protection (where applicable)
[ ] Access controls on Update/Delete operations
[ ] Asset ID validated in all asset operations
[ ] Asset transfers use pull pattern to avoid DoS
[ ] Inner transaction fees explicitly set to 0
[ ] OnComplete field validated for ApplicationCall transactions
[ ] Tealer scan completed with no critical/high findings
[ ] Unit tests cover all vulnerability scenarios
[ ] Coverage table emitted with all 11 rows, each carrying a verdict of
found,clearorn/awith a reason
13. Rationalizations to Reject
"The contract is small, so most patterns obviously don't apply." Obvious to whom? An
n/acosts one clause and makes the judgment reviewable. Silence records nothing, and a reader cannot tell it apart from not having checked."Tealer reported nothing, so the contract is clean." Tealer covers a subset of these 11 patterns and does not reach the logic-level ones at all. A clean tool run is one row of evidence, not a verdict on the patterns it never examined. Say which patterns it covered.
"I checked the patterns that matter for this contract." Deciding which patterns matter is the scan, not a precondition for starting it. Rank by severity after the table is complete, not by leaving rows out.
"No findings, so there is nothing to report." A zero-finding scan still emits the full coverage table. That table is the deliverable: it is what distinguishes a contract that was examined from one that was glanced at.
"PyTeal/Beaker handles this." Name the version and the mechanism. Framework defaults change between releases, and a framework that covers a pattern on one call path often does not on another.
"The RekeyTo check is in the other program." Then cite it. A validation you believe exists elsewhere is an assumption until you have the
file:line, and split-program contracts are where these checks go missing.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.

shall not be interpreted to, reduce, limit, restrict, or impose
conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the
Licensor.
d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.
