CVE-2026-11416

CVE-2026-11416 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. MoviePilot contains a path traversal vulnerability in the AliPan, U115, and Rclone cloud storage download handlers where the local destination path is constructed by concatenating the configured download directory with a filename taken directly from remote cloud API metadata without basename normalization or path validation. An attacker who controls a filename returned by a remote cloud storage API can include traversal sequences ../ in the filename to cause downloaded content to be written outside the configured download directory, potentially overwriting arbitrary files including configuration or plugin files reachable by the application process.. EPSS estimates a 0.47% chance of exploitation in the next 30 days.
