CVE-2026-110234 | BDVDB-2026-388813 Detail
elio-fmelio
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact high, availability impact none. Attack vector: local.
Weaknesses#
