Technical details

An improper input validation vulnerability (CWE-20) exists in the Adobe Content Authenticity Initiative (CAI) Content Credentials SDKs, specifically affecting c2pa-web versions <= 0.7.1 and c2pa-rs (v0.80.1 and earlier). The flaw allows a remote, unauthenticated attacker to provide malformed input that the library fails to process safely, resulting in an application crash. The attack vector is network-based and requires no prior privileges or user interaction. This leads to a complete loss of availability for the affected component. Adobe has addressed this in the Content Authenticity SDK via APSB26-61.
