Summary

This findings report highlights instances of unsafe ABI encodings identified within the codebase. The occurrences are found in various contracts, including LibEvaluate.sol, LibGauge.sol, LibTokenSilo.sol, and LibWhitelist.sol. These unsafe ABI encodings pose a risk due to potential errors caused by lack of type safety and vulnerability to typos.

Vulnerability Details

LibEvaluate.sol (Line 331):
Unsafe ABI encoding is used on line 331 of LibEvaluate.sol.

LibGauge.sol (Line 191):
Unsafe ABI encoding is used on line 191 of LibGauge.sol.

LibTokenSilo.sol (Line 467, 469):
Unsafe ABI encoding is used on lines 467 and 469 of LibTokenSilo.sol.

LibWhitelist.sol (Line 236, 245):
Unsafe ABI encoding is used on lines 236 and 245 of LibWhitelist.sol.

Impact

The usage of unsafe ABI encodings can lead to various risks, including:

Type Mismatch: Inappropriate parameter types passed to function calls can result in unexpected behavior or runtime errors.

Typo Vulnerabilities: Mistakes in function signatures due to typos can lead to unintended function calls or failures.

Security Risks: Lack of type safety and typo vulnerabilities increase the likelihood of contract vulnerabilities and potential exploits.

Tools Used

The findings were identified through manual code review and analysis. No specific automated tools were used for this assessment.

Recommendations

Replace with abi.encodeCall:
Consider replacing all instances of unsafe ABI encodings with abi.encodeCall. This method provides type safety by verifying whether the supplied values match the expected types of the called function parameters. It also reduces the risk of errors caused by typos.
