CVE-2026-48378: Adobe Content Credentials SDK multiple security feature bypasses

CVE-2026-48378 · Severity: medium · CVSS 5.3 · Published 2026-10-13

Adobe Content Credentials SDK is a set of libraries used to verify the authenticity and provenance of digital content. Multiple vulnerabilities in input validation, certificate verification, and cryptographic signature checking could allow attackers to bypass security protections and forge or tamper with content credentials without user interaction. This could enable unauthorized modification of digital asset authenticity records and undermine trust in content provenance systems.

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