Vulnerability Details CVE-2026-110204
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. Attackers using indirect prompt injection can embed denied commands inside an allowlisted command like echo to execute them without user approval on bash 5.3+ or ksh93.
