Which packages are affected by GHSA-534w-2vm4-89xr?

GHSA-534w-2vm4-89xr affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix GHSA-534w-2vm4-89xr?

Update openclaw to 2026.2.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-534w-2vm4-89xr is resolved across your whole dependency graph.

How do I detect GHSA-534w-2vm4-89xr in my npm dependencies?

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.

How do I mitigate GHSA-534w-2vm4-89xr if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-534w-2vm4-89xr?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-534w-2vm4-89xr can be triaged on real exposure rather than presence alone.

Is GHSA-534w-2vm4-89xr actively exploited in the wild?

No public exploit code has been indexed for GHSA-534w-2vm4-89xr yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-534w-2vm4-89xr published, and has it been updated?

GHSA-534w-2vm4-89xr was published on March 3, 2026 and was last updated on March 4, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A missing group-sender authorization check in the Zalo plugin allowed unauthorized GROUP messages to enter agent dispatch paths in configurations intended to restrict group traffic.

Impact

When Zalo group handling was configured with allowlist-style controls, a sender not present in the intended group allowlist could still trigger agent processing through the GROUP message path.

Root Cause

Group access checks were not consistently enforced before dispatch for Zalo GROUP messages. The fix adds explicit runtime group-policy evaluation (groupPolicy, groupAllowFrom, fallback to allowFrom) and fail-closed behavior for missing provider config.
