## Technical details

An improper input validation vulnerability (CWE-20) exists in the Adobe Content Authenticity Initiative (CAI) SDKs, specifically affecting the c2pa-web and c2pa-rust implementations. The flaw allows an attacker to provide specially crafted input that causes the application to crash, resulting in a denial-of-service (DoS). The attack vector is classified as local, but notably requires no prior authentication or user interaction to trigger the crash. Affected versions include c2pa-web at or below 0.7.1 and c2pa-rust at or below 0.80.1. Users are advised to update to the latest versions provided by Adobe to mitigate this risk.
