CVE-2026-113352

HighCVSS 7.5
Published: Updated: Translated: NVD NIST

Summary

uTox through 0.18.1 contains a path traversal vulnerability that allows Tox friends to write arbitrary files by sending absolute or ../ file names to victims with auto-accept enabled. Attackers can overwrite shell startup files or plant crafted .ftinfo resume records that ft_find_resumeable() loads, abusing FILE pointers to write /proc/self/mem and execute code.

Risk Assessment

A remote Tox friend can overwrite user files and achieve code execution on the victim's system.

Recommendation

Update uTox to a version later than 0.18.1 and disable automatic file acceptance.
