The vulnerability stems from uncontrolled resource consumption (CWE-400) during signature verification. The advisory indicates the default maxSignatureAttempts parameter allowed endless processing of signatures from a compromised registry. The fix in v1.0.0-rc.6 likely introduced a limit check in the signature verification loop. The verifySignatures function (or equivalent) in the verification workflow would be responsible for iterating through signatures, and without a proper maxSignatureAttempts enforcement, it would cause resource exhaustion. This aligns with the vulnerability's impact description and the CWE classification.
