CVE-2026-104345 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials SDK, a library for embedding and verifying content authenticity metadata, contains multiple input validation and certificate handling flaws that allow attackers to bypass security protections without user interaction. An attacker could exploit these issues to forge or tamper with content credentials, undermining the integrity verification that organizations rely on to authenticate media sources and detect unauthorized modifications.
