CVE-2026-62294 (opens in a new tab)How to fix?
Upgrade Debian:14 flameshot to version 14.0.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream flameshot package and not the flameshot package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
Flameshot is powerful yet simple to use screenshot software. Prior to 14.0.0, the Open With feature wrote screenshots to a predictable temporary path and followed symlinks, creating a time-of-check to time-of-use race that allowed a local unprivileged attacker on the same machine to pre-plant a symlink and cause Flameshot to write PNG data through it, overwriting any file the victim user could write. This issue is fixed in version 14.0.0.
