CVE-2026-62294

MEDIUMCVSS 5.1/10

Last modified

CVE-2026-62294 is a medium-severity vulnerability rated 5.1/10 on the CVSS scale. 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.
