What is CVE-2026-110203?

Roo Code versions up to 3.54.0 are susceptible to a command approval bypass vulnerability. This flaw enables attackers to circumvent the user approval mechanism for shell commands. By exploiting weaknesses in the quote-masking regex within the parseCommandLine() function, attackers can leverage indirect prompt injection techniques. They can hide command delimiters using allowed prefixes, such as 'echo', thereby executing commands without user consent. This vulnerability poses significant security risks and underscores the importance of timely updates and scrutiny of code execution mechanisms.

Affected Version(s)

Roo-Code 0 <= 3.54.0
