Zodiac Releases Security Report on ERC-1271 Verification Flaw in Roles Modifier

According to ChainCatcher, Zodiac has released a security analysis report revealing a flaw in the ERC-1271 transaction signature verification logic used by its Roles Modifier. The vulnerability stems from the system validating signatures based solely on the returned "magic value" without verifying whether the call itself succeeded, potentially allowing attackers to bypass module authentication by disguising failed verifications as valid signatures.
