CVE-2026-106627: Adobe Content Credentials uncontrolled resource consumption denial-of-service

CVE-2026-106627 · Severity: high · CVSS 7.5 · Published 2026-10-13

Adobe Content Credentials SDK is used to manage digital provenance and authenticity metadata for media files. Multiple uncontrolled resource consumption vulnerabilities allow an attacker to exhaust system resources without authentication, causing the application to become unavailable. No user interaction is required to trigger these flaws, making them immediately exploitable.

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