CVE-2026-95632: Adobe Content Credentials improper cryptographic signature verification

CVE-2026-95632 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials SDK, which verifies the authenticity and integrity of digital content through cryptographic signatures, contains multiple flaws in how it validates these signatures. An attacker can bypass security protections and gain unauthorized write access to content without requiring user interaction, compromising the trustworthiness of digitally signed materials.

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

Am I affected by CVE-2026-95632?
Check whether you run Adobe C2pa, Adobe C2PA Tool, 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 vulnerability stems from improper verification of cryptographic signatures (CWE-347) in the Content Credentials SDK components, alongside related input validation and certificate validation flaws that all result in security feature bypass. Attack vectors are network-based with no authentication or user interaction required. An attacker can forge or tamper with signed content by circumventing signature verification, gaining unauthorized write access to protected resources.
