CVE-2026-103294: Adobe Content Credentials improper certificate validation security feature bypass

CVE-2026-103294 · Severity: medium · CVSS 5.9 · Published 2026-10-13

Adobe Content Credentials SDK, a toolkit for managing digital authenticity and provenance of media files, contains multiple improper certificate validation flaws that allow attackers to bypass security features protecting the integrity and authenticity of content credentials. Exploits do not require user interaction and could enable unauthorized modification of content metadata or signature verification systems. Adobe has released updates and is unaware of active exploitation.

Technologies: Adobe C2pa, Adobe C2PA Tool, Adobe C2pa-Web, Adobe C2patool, Adobe Content Credentials JS SDK, Adobe Content Credentials Rust SDK. Vendors: Adobe.
