CVE-2026-110234
Published:October 13, 2026
Updated:October 14, 2026
Elio through 1.13.0 contains an insecure temporary file vulnerability that allows local users to overwrite another user's files by pre-creating symbolic links at predictable capture paths. Attackers who know the victim's Elio process ID can plant a symlink so previewing media, fonts or archives truncates and overwrites victim-owned files.
