CVE-2026-105902: Adobe Content Credentials SDK uncontrolled resource consumption and signature bypass

CVE-2026-105902 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials SDK, which provides digital credential and authenticity verification for digital content, is affected by multiple vulnerabilities including uncontrolled resource consumption and cryptographic signature bypass flaws. An attacker could exploit these issues to cause denial-of-service conditions or bypass security verification features that protect content authenticity. No user interaction is required for exploitation.

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

Technical details

The advisory discloses multiple vulnerabilities across three Content Credentials products: the Rust SDK, C2PA Tool, and JavaScript SDK. Issues include uncontrolled resource consumption (CWE-400), improper input validation (CWE-20), certificate validation bypasses (CWE-295), and cryptographic signature verification failures (CWE-347), all reachable over the network without authentication or user interaction. Successful exploitation enables denial-of-service, security feature bypass, and arbitrary file system writes.
