{"id":"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: `\u003c= 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. This advisory now marks `\u003e= 2026.2.24` as patched.","modified":"2026-03-04T15:11:34.403518Z","published":"2026-03-03T23:18:26Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-03T23:18:26Z","nvd_published_at":null,"cwe_ids":["CWE-284","CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-534w-2vm4-89xr"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/b4010a0b627025c809c0e5dbdbd4770f3bc59ef8"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.24"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-534w-2vm4-89xr/GHSA-534w-2vm4-89xr.json","last_known_affected_version_range":"\u003c= 2026.2.23"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
