Overview
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the JwsJsonContainerRequestFilter method. An attacker can cause the system to process unauthenticated metadata by crafting a request where the first signature entry is not properly validated, potentially bypassing assumptions about the authenticity of Content-Type or protected HTTP-header metadata and influencing downstream entity parsing or header consistency checks.
