Summary

cjbassi/gotop is vulnerable to local argument injection via its process termination functionality. The process name is passed directly to pkill without sanitization, so a local attacker can create a process with a crafted name beginning with -- (e.g. containing a target user's UID). When the user running gotop invokes the kill feature on that process, pkill interprets the crafted name as a command-line option, terminating all processes owned by the targeted user. The product is no longer actively supported and the vulnerability has not been fixed; it was confirmed at version 3.0.0.

Risk Assessment

A local attacker can cause mass termination of processes owned by a chosen user, leading to data loss or service disruption. The lack of support and fixes means the risk remains indefinitely.

Recommendation

Stop using cjbassi/gotop or replace it with an actively maintained tool, as the vulnerability will not be fixed. If use is unavoidable, restrict privileges of users running gotop and avoid using the kill feature on untrusted processes.
