GHSA-wcxr-59v9-rxr8 — openclaw
HIGHGHSA-wcxr-59v9-rxr8 is a high-severity (CVSS 8.4) CWE-863 vulnerability in openclaw. A fix is available for openclaw — see the affected versions and patch details below.
`OpenClaw: session_status` let sandboxed subagents access parent or sibling session state
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-wcxr-59v9-rxr8 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
openclawnpmDescription
Summary
The built-in session_status tool did not enforce the intended session-visibility boundary. A sandboxed subagent could supply another session's sessionKey and inspect or modify state outside its own sandbox scope.
Impact
This allowed a sandboxed child session to read parent or sibling session data and, in affected releases, update the target session's persisted model override.
Affected versions
openclaw <= 2026.3.8
Patch
Fixed in openclaw 2026.3.11 and included in later releases such as 2026.3.12. Session visibility checks now enforce the sandbox boundary before reading or mutating session state.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openclaw to 2026.3.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wcxr-59v9-rxr8 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-wcxr-59v9-rxr8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-wcxr-59v9-rxr8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-wcxr-59v9-rxr8 in your dependencies?
O3 Security finds GHSA-wcxr-59v9-rxr8 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
