Local file disclosure via malicious file processing
Published Aug 25, 2026 · Updated Aug 27, 2026
Improper input validation in C2PA Tool 0.26.70 and earlier and Content Credentials Rust SDK 0.89.0 and earlier allows attackers to read local files. Adobe has not disclosed which parser or input field fails validation or how the local file contents become accessible. Exploitation requires a victim to open a malicious file, and the reported impact is limited to reading files and directories.
