CVE-2026-62294 Details
Description
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.
A vulnerability in Flameshot's 'Open With' feature prior to version 14.0.0 allows local, unprivileged attackers to exploit a time-of-check to time-of-use (TOCTOU) race condition. The feature writes screenshots to a predictable temporary path and follows symlinks, enabling attackers to pre-plant a symlink and have Flameshot overwrite any file the victim user can write to, such as configuration files. This issue has been fixed in version 14.0.0.
Users can upgrade to Flameshot version 14.0.0 or later to address this vulnerability.
