CVE-2026-82536 RooCodeInc CVE debrief
CVE-2026-82536 is a high-severity vulnerability in Roo-Code through version 3.54.0, which allows attackers to bypass auto-approve functionality and execute denied shell commands. The vulnerability exists in the shell command parsing logic, where an attacker can craft a command line with an allowlisted prefix followed by the stderr-redirecting pipe operator and a denied command. This causes the parser to approve the full pipeline while bash executes the denied component with the agent's auto-execute privileges on the developer's machine.

Who should care
Defenders responsible for Roo-Code installations, developers using Roo-Code, and security teams should assess exposure and prioritize patching to prevent exploitation. This includes reviewing and restricting auto-execute privileges for agents, monitoring command-line activity for suspicious pipeline constructions, and implementing compensating controls such as command whitelisting or strict access controls. Additionally, defenders should verify and patch
Why it matters
CVE-2026-82536 is a high-severity vulnerability in Roo-Code that allows attackers to bypass auto-approve functionality and execute denied shell commands. Defenders should prioritize verifying and patching affected installations to prevent exploitation.
- Attackers can execute arbitrary commands with auto-execute privileges on the developer's machine.
- The vulnerability allows for potential lateral movement and exploitation within the network.
- Defenders need to verify and patch affected Roo-Code installations to prevent exploitation.
- The vulnerability requires verification of affected versions and remediation efforts.
Technical summary
The vulnerability exists in the shell command parsing logic of Roo-Code, where an attacker can craft a command line with an allowlisted prefix followed by the stderr-redirecting pipe operator and a denied command. This causes the parser to approve the full pipeline while bash executes the denied component with the agent's auto-execute privileges on the developer's machine. The vulnerability allows attackers to execute arbitrary commands with auto-execute privileges, potentially leading to lateral movement and exploitation within the network. Defenders should prioritize verifying and patching affected Roo-Code installations to prevent exploitation.
Defensive priority
Defenders should prioritize verifying and patching affected Roo-Code installations, as the vulnerability allows attackers to execute arbitrary commands with auto-execute privileges.
Recommended defensive actions
- Verify and patch affected Roo-Code installations to prevent exploitation.
- Review and restrict auto-execute privileges for agents to limit potential damage.
- Monitor command-line activity for suspicious pipeline constructions.
- Implement compensating controls, such as command whitelisting or strict access controls.
- Review relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
