CVE-2026-91784

medium

Description

cjbassi/gotop is vulnerable to local argument injection via process termination functionality. The process name is passed directly to pkill without sanitization. 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. Product is no longer actively supported and the vulnerabilities have not been fixed. Vulnerability was confirmed at version 3.0.0; other versions were not tested but may also be affected.
