CVE-2026-57997 Strapi users-permissions - JWT Algorithm Confusion via Missing Algorithm Configuration

Strapi users-permissions plugin fails to restrict JWT algorithms when plugin::users-permissions.jwt.algorithm is not explicitly configured, allowing acceptance of HS384 and HS512 tokens alongside HS256. Attackers possessing the jwtSecret can mint tokens with non-standard HMAC variants to bypass...

CVE-2026-57997

The CVE concerns the Strapi users-permissions plugin where JWT algorithm restrictions are not enforced if plugin::users-permissions.jwt.algorithm is not explicitly configured. This allows the server to accept HS384 and HS512 tokens alongside HS256. An attacker who possesses the jwtSecret can mint...

CVE-2026-12616

The /v1/upload/sbom endpoint extracts the iss claim from the attacker-supplied JWT with signature verification disabled, then interpolates that string into three log statements before any validation gate. Because the configured log format "%asctimes - %names - %levelnames - %messages" renders...
