Vulnerability Data

Roo Code through 3.54.0 contains a command approval bypass vulnerability that allows attackers to auto-approve denied shell commands by abusing quote-masking regex in parseCommandLine(). Attackers can use indirect prompt injection with escaped or single-quoted double quotes to hide command separators…

behind allowlisted prefixes like echo, executing commands without user approval.

Mitigating Controls

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

A.8.25 mandates a secure SDLC process with checkpoints, secure coding, testing and training; it does not stop differing interpretations of shared state or inputs between two products from arising or being exploited

blocks

A.8.26 only requires that security requirements (including resilience against injections or input controls) be identified and specified during development or acquisition; it does not itself enforce, implement or assure any mechanism that stops an interpretation conflict from being exploitable.

blocks

A.8.27 establishes and applies secure-by-design principles (defense-in-depth, least privilege, assume-breach, distrust-external-input, hardening, etc.) but does not stop two products from interpreting the same input or protocol step differently; the resulting state/conflict weakness can still be present and exploitable.

prevents

Secure coding standards can enforce canonical input handling and strict protocol compliance to avoid misinterpretation between products.

finds

Security testing can detect and correct cases where one component misinterprets another’s state or messages.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-436, a class-level weakness, and none of its children carries one either.
