## What is CVE-2026-110234?

CVE-2026-110234 is a medium-severity path traversal vulnerability in elio-fm elio, published on 13 Oct 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official 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.

Weakness: CWE-377 (DEPRECATED: Insecure Temporary File)
