Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Attackers can bypass audience verification due to inadequate type assertions when the audience claim contains a list of strings instead of a single string, directly leading to CVE-2020-26160.
Auth Bypass: Custom verification errors returned by key function callbacks were wrapped and overridden during parsing, potentially causing applications to bypass strict signature validation checks.
Auth Bypass: Allowing raw byte slices instead of strongly typed RSA keys in signing and verification methods enables signature bypasses or key-type confusion attacks.
