Summary

Flameshot prior to version 14.0.0 has a vulnerability in the 'Open With' feature that writes screenshots to a predictable temporary path and follows symlinks. This allows a local unprivileged attacker on the same machine to pre-plant a symlink and overwrite any file the victim user can write.

Risk Assessment

An attacker can overwrite critical user files such as system configurations, startup scripts, or personal data, potentially leading to privilege escalation, data loss, or malicious code execution.

Recommendation

Immediately upgrade Flameshot to version 14.0.0 or later, which fixes this vulnerability by securely handling temporary paths.

Original NVD description (English source)

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.
