Technical details

The Content Credentials SDK contains multiple improper verification of cryptographic signatures (CWE-347), improper certificate validation (CWE-295), and input validation flaws (CWE-20) that enable signature bypass. These vulnerabilities are remotely exploitable over the network with no authentication or user interaction required, allowing attackers to forge or tamper with content metadata and claims.
