Description Vladimir Vasilev 2026-10-16 18:40:23 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Vifm 0.8.1-beta through 0.14.4 reuses a pre-existing IPC FIFO in the shared temporary directory without checking ownership, allowing local users to execute commands as another user. Attackers can pre-create a world-writable vifm-ipc-vifm FIFO and write IPC packets with -c and ! shell commands that execute with the victim's privileges.
