Details
A vulnerability classified as critical was found in Packistry up to 0.12.x. Affected by this vulnerability is the function RepositoryAwareController::authorize. The manipulation with an unknown input leads to a improper authentication vulnerability. The CWE definition for the vulnerability is CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. As an impact it is known to affect confidentiality. The summary by CVE is:
Packistry is a self-hosted Composer repository designed to handle PHP package distribution. Prior to version 0.13.0, RepositoryAwareController::authorize() verified token presence and ability, but did not enforce token expiration. As a result, an expired deploy token with the correct ability could still access repository endpoints (e.g., Composer metadata/download APIs). The fix in version 0.13.0 adds an explicit expiration check, and tests now test expired deploy tokens to ensure they are rejected.
