CVE-2026-103297 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials SDKs are libraries used to verify the authenticity and integrity of digital media through cryptographic signatures. Multiple vulnerabilities in the signature verification logic, certificate validation, and input handling could allow attackers to forge or tamper with credentials without detection, compromising the trustworthiness of authenticated media. No user interaction is required to exploit these issues.

**Which products and versions are affected?** Adobe C2PA Tool (c2patool) c2patool-v0.27.15 and earlier; Adobe Content Credentials JS SDK (@contentauth/c2pa-web) @contentauth/c2pa-web@0.13.4 and earlier; Adobe Content Credentials Rust SDK (c2pa) c2pa-v0.90.15 and earlier.

**Is there a fix for CVE-2026-103297?** Yes: fixed in Content Credentials Rust SDK c2pa-v0.91.1, C2PA Tool c2patool-v0.28.1, Content Credentials JS SDK @contentauth/c2pa-web@0.15.3. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-103297 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-103297?** Check whether you run Adobe C2pa, Adobe C2PA Tool (c2patool), Adobe C2pa-Web or one of the others listed at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in Content Credentials Rust SDK c2pa-v0.91.1, C2PA Tool c2patool-v0.28.1, Content Credentials JS SDK @contentauth/c2pa-web@0.15.3

## Technical details

The advisory addresses 21 vulnerabilities across three Content Credentials SDK implementations (Rust, C2PA Tool, and JavaScript) including improper cryptographic signature verification (CWE-347), certificate validation bypass (CWE-295), input validation flaws (CWE-20), SSRF (CWE-918), access control issues (CWE-284), and resource consumption weaknesses. Exploitation requires only network access with no authentication or user interaction, allowing attackers to bypass security features, forge credentials, cause denial-of-service, or achieve arbitrary filesystem writes. All issues have been patched in updated versions.

## Affected products

- Adobe Content Credentials Rust SDK (c2pa) c2pa-v0.90.15 and earlier
- Adobe C2PA Tool (c2patool) c2patool-v0.27.15 and earlier
- Adobe Content Credentials JS SDK (@contentauth/c2pa-web) @contentauth/c2pa-web@0.13.4 and earlier
