Source: NVD(opens in a new tab)
Identifier: CVE-2026-110204
Published: October 13, 2026
Record updated: October 14, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

Roo Code through 3.54.0 has a command approval bypass. Its parseCommandLine() function treats ${ command; } substitutions as parameter expansions, so attackers using indirect prompt injection can hide denied shell commands inside an allowlisted command such as echo. The commands run without user approval on bash 5.3+ or ksh93.

Mitigation

The source does not state a fix yet. Check the original advisory for updates.
