Security readout for executives and security teams
Plain-English summary
OpenClaw versions before 2026.3.11 can let a sandboxed subagent cross session boundaries. A low-privileged actor could read or alter parent or sibling session data, including persisted model overrides. This is serious because sandbox isolation is a core trust boundary.
Executive priority
Treat this as urgent for any OpenClaw environment using subagents. The issue affects session isolation and could expose or alter sensitive agent state. Prioritize upgrade and targeted review of session data integrity.
Technical view
The flaw is an authorization issue in the session_status tool. It accepts arbitrary sessionKey values, allowing access to session state outside the subagent sandbox. The CVSS 4.0 score is 9.2, with local attack vector, low privileges, no user interaction, and high confidentiality and integrity impact.
Likely exposure
Exposure is limited to OpenClaw deployments running versions before 2026.3.11 where sandboxed subagents can use session_status. The provided sources do not identify additional affected products, hosted services, or specific configurations beyond OpenClaw.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires low privileges and local access per the CVSS vector, but does not require user interaction. The practical risk is cross-session data access or unauthorized state modification.
Researcher notes
Evidence supports CWE-863 improper authorization. The key boundary failure is missing authorization on caller-supplied sessionKey values. The sources do not provide public exploit evidence, weaponized details, or affected products beyond OpenClaw before 2026.3.11.
Mitigation direction
- Upgrade OpenClaw to 2026.3.11 or later.
- Review the GitHub advisory for vendor-specific remediation guidance.
- Limit sandboxed subagent access to session_status until patched.
- Audit persisted model overrides for unexpected changes.
- Check vendor guidance before applying compensating controls.
Validation and detection
- Inventory OpenClaw deployments and confirm running versions.
- Identify environments using sandboxed subagents.
- Verify whether session_status is available to sandboxed subagents.
- Review logs for unusual cross-session sessionKey access.
- Check persisted model overrides for unauthorized changes.

CWE-863: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupPrivilege behavior lookup
The CVE wording references privilege impact, so privilege escalation and authorization behavior review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
