- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-x2ff-j5c2-ggpr.
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-x2ff-j5c2-ggpr 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
Impact
In shared Slack workspace deployments that rely on sender restrictions (allowFrom, DM policy, or channel user allowlists), some interactive callbacks (block_action, view_submission, view_closed) could be accepted before full sender authorization checks.
In that scenario, an unauthorized workspace member could enqueue system-event text into an active session. This issue did not provide unauthenticated access, cross-gateway isolation bypass, or host-level privilege escalation by itself.

Release Process Note
patched_versions is pre-set to the release (2026.2.25). Advisory published with npm release 2026.2.25.
Trust Model Scope Note
OpenClaw does not support adversarial multi-user isolation on a single shared gateway instance. The supported model is one trust boundary per gateway (separate gateways/hosts for mutually untrusted users). See: https://docs.openclaw.ai/gateway/security
OpenClaw thanks @tdjackey for reporting.

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 2026.2.25 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x2ff-j5c2-ggpr 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-x2ff-j5c2-ggpr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-x2ff-j5c2-ggpr. 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-x2ff-j5c2-ggpr in your dependencies?
O3 Security finds GHSA-x2ff-j5c2-ggpr across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
