CVE-2023-52076Public exploit

Code execution via unchecked EPUB extraction paths

Published Jan 25, 2024 · Updated Jun 17, 2025

Path traversal in MATE Desktop Atril before 1.26.2 allows attackers to write files by opening a crafted EPUB document. The EPUB extractor appends archive entry names to its temporary-directory path without verifying that each resolved output remains inside that directory. Opening the document is required; a new autostart file can execute commands at the next login, but existing files cannot be overwritten.
