{"id":"GHSA-xg59-f45v-9r9j","summary":"Duplicate Advisory: OpenClaw's MS Teams sender allowlist bypass when route allowlist is configured and sender allowlist is empty","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-g7cr-9h7q-4qxq. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.3.8 contains a sender allowlist bypass vulnerability in its Microsoft Teams plugin that allows unauthorized senders to bypass intended authorization checks. When a team/channel route allowlist is configured with an empty groupAllowFrom parameter, the message handler synthesizes wildcard sender authorization, permitting any sender in the matched team/channel to trigger replies in allowlisted Teams routes.","modified":"2026-04-06T23:06:31.123686Z","published":"2026-03-31T12:31:36Z","withdrawn":"2026-04-06T22:45:43Z","database_specific":{"cwe_ids":["CWE-863"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-04-06T22:45:43Z","nvd_published_at":"2026-03-31T12:16:30Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-g7cr-9h7q-4qxq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34506"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/88aee9161e0e6d32e810a25711e32a808a1777b2"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-sender-allowlist-bypass-in-microsoft-teams-plugin-via-route-allowlist-configuration"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-xg59-f45v-9r9j/GHSA-xg59-f45v-9r9j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
