{"id":"GHSA-534w-2vm4-89xr","aliases":[],"url":"https://o3.security/vulnerability/GHSA-534w-2vm4-89xr","summary":"OpenClaw's Zalo group sender allowlist bypass permits unauthorized GROUP dispatch","details":"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.\n\n## Impact\nWhen 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.\n\n## Root Cause\nGroup 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.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published vulnerable version: `2026.2.23` (as of 2026-02-24)\n- Affected range: `<= 2026.2.23`\n- Planned patched version: `2026.2.24`\n\n## Fix Commit(s)\n- `b4010a0b627025c809c0e5dbdbd4770f3bc59ef8`\n\nOpenClaw thanks @tdjackey for reporting.\n\n### Publication Update (2026-02-25)\n`openclaw@2026.2.24` is published on npm and contains the fix commit(s) listed above.
