CVE-2026-110204 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Roo Code through 3.54.0 contains a command approval bypass vulnerability that allows attackers to run denied shell commands because parseCommandLine() treats ${ command; } substitutions as parameter expansions.

EPSS estimates a 0.49% chance of exploitation in the next 30 days.
