CVE-2026-48312

Unauthorized writes via undisclosed input validation flaw

Published Jul 14, 2026 · Updated Jul 14, 2026

Improper input validation in Adobe Content Credentials products allows local users to bypass a security feature and gain write access. Adobe reports affected Rust SDK, c2patool, and c2pa-web versions but has not disclosed the input, validation locus, bypassed control, or write target. Exploitation requires local execution but no prior privileges or user interaction, enabling unauthorized modification and limited data exposure.
