Redirect chains were not consistently constrained to allowlisted targets before accepting fetched content.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected versions: `<= 2026.2.21-2` (latest published at triage time)\n- Fixed in: `2026.2.22` (planned next release)\n\n## Impact\nAttackers able to supply or influence attachment URLs could force redirect chains to non-allowlisted targets, weakening SSRF boundary controls for MSTeams media ingestion.\n\n## Fix Commit(s)\n- `73d93dee64127a26f1acd09d0403b794cdeb4f5c`\n- `b34097f62df9d1960cc22600269cd3f3284e2124`\n\n## Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.22`). Once that npm release is published, this advisory can be published without further version-field edits.\n\nOpenClaw thanks @tdjackey for reporting.","published":"2026-03-19T22:07:11.641Z","modified":"2026-08-12T03:51:39.438647584Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.22"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/73d93dee64127a26f1acd09d0403b794cdeb4f5c","label":"openclaw/openclaw@73d93de"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32037.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-w76h-8m22-hpgh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32037"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-redirect-chain-bypass-of-media-host-allowlist-in-msteams-attachment-handling"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/73d93dee64127a26f1acd09d0403b794cdeb4f5c"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b34097f62df9d1960cc22600269cd3f3284e2124"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.438647584Z"}}
