{"id":"GHSA-j4xf-96qf-rx69","summary":"OpenClaw has a Feishu allowFrom authorization bypass via display-name collision","details":"### Summary\n\nFeishu allowlist authorization could be bypassed by display-name collision.\n\n### Details\n\n`channels.feishu.allowFrom` is documented as an ID-based allowlist (open_id list), but Feishu policy matching accepted mutable sender display names in the same namespace. An attacker could set a display name equal to an allowlisted ID string and pass authorization checks.\n\nThe fix enforces ID-only matching for Feishu allowlist checks, normalizes Feishu ID prefixes during comparison, and ignores mutable display names for authorization.\n\n### Impact\n\nDeployments using Feishu allowlist-based authorization could incorrectly authorize non-allowlisted senders when a colliding display name was used.\n\n### Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Latest published version at triage time: `2026.2.21-2`\n- Affected range: `\u003c= 2026.2.21-2`\n- Planned patched version: `\u003e= 2026.2.22`\n\n### Fix Commit(s)\n\n- `4ed87a667263ed2d422b9d5d5a5d326e099f92c7`\n\n### Release Process Note\n\n`patched_versions` is pre-set to the planned next release (`\u003e= 2026.2.22`) so the advisory is ready to publish once that npm release is available.\n\nOpenClaw thanks @jiseoung for reporting.","aliases":["CVE-2026-32021"],"modified":"2026-03-30T13:33:53.160138Z","published":"2026-03-03T21:41:38Z","database_specific":{"github_reviewed_at":"2026-03-03T21:41:38Z","nvd_published_at":"2026-03-19T22:16:36Z","cwe_ids":["CWE-639","CWE-863"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-j4xf-96qf-rx69"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32021"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/4ed87a667263ed2d422b9d5d5a5d326e099f92c7"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-display-name-collision-in-feishu-allowfrom"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-j4xf-96qf-rx69/GHSA-j4xf-96qf-rx69.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:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
