Last modified Jun 17, 2026

CVE-2021-21908 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Specially-crafted command line arguments can lead to arbitrary file deletion. The handle_delete function does not attempt to sanitize or otherwise validate the contents of the [file] parameter (passed to the function as argv[1]), allowing an authenticated attacker to supply directory traversal primitives and delete semi-arbitrary files.. EPSS estimates a 1.44% chance of exploitation in the next 30 days.
