CVE-2021-46743
Key/algorithm type confusion
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD, GHSA.
Description
In Firebase PHP-JWT before 6.0.0, an algorithm-confusion issue (e.g., RS256 / HS256) exists via the kid (aka Key ID) header, when multiple types of keys are loaded in a key ring. This allows an attacker to forge tokens that validate under the incorrect key. NOTE: this provides a straightforward way to use the PHP-JWT library unsafely, but might not be considered a vulnerability in the library itself.
