CVE-2026-102502: Adobe Content Credentials SDK improper cryptographic signature verification

CVE-2026-102502 · Severity: medium · CVSS 5.3 · Published 2026-10-13

Adobe Content Credentials SDK is used to embed and verify digital provenance information in media files. Multiple improper signature verification and validation flaws allow attackers to bypass security features and modify files without detection, potentially resulting in compromised content authentication and file tampering. No user interaction is required to exploit these vulnerabilities.

Technologies: Adobe C2pa, Adobe C2PA Tool (c2patool), Adobe C2pa-Web, Adobe C2patool, Adobe Content Credentials JS SDK, Adobe Content Credentials Rust SDK (c2pa). Vendors: Adobe.

Technical details

The Adobe Content Credentials SDK contains multiple flaws in cryptographic signature verification (CWE-347), certificate validation (CWE-295), and input validation (CWE-20), as well as SSRF vulnerabilities (CWE-918). These allow network-accessible attackers to bypass security features and gain unauthorized write access to protected content without authentication or user interaction. The issues span the Rust SDK, JavaScript SDK, and C2PA Tool components.
