CVE-2026-100113 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials is a toolkit for managing digital authentication and integrity of media and documents. Improper input validation flaws allow attackers to bypass security measures and gain unauthorized write access to protected credentials without requiring user interaction. This could enable attackers to forge or tamper with authenticated content across multiple Adobe Content Credentials products.
