Technical details

An integer overflow or wraparound vulnerability (CWE-190) exists in the Adobe Content Authenticity Initiative (CAI) SDK, specifically affecting the c2pa-web and c2pa-v (Rust) implementations. The flaw allows a remote, unauthenticated attacker to trigger an application crash by providing specially crafted input that causes an integer calculation to overflow. This results in a denial-of-service (DoS) condition. The vulnerability is reachable over the network and does not require user interaction. Users are advised to update to the latest versions of the SDK as outlined in Adobe advisory APSB26-61.

Affected products

Adobe c2pa-web 0.7.1 and earlier
Adobe c2pa-rust (c2pa-v) 0.80.1 and earlier
