{"id":"CVE-2026-28465","aliases":["GHSA-3m3q-x3gj-f79x"],"url":"https://o3.security/vulnerability/CVE-2026-28465","summary":"OpenClaw voice-call < 2026.2.3 - Webhook Verification Bypass via Forwarded Headers","details":"## Affected Packages / Versions\n\nThis issue affects the optional voice-call plugin only. It is not enabled by default; it only applies to installations where the plugin is installed and enabled.\n\n- Package: `@openclaw/voice-call`\n- Vulnerable versions: `< 2026.2.3`\n- Patched versions: `>= 2026.2.3`\n\nLegacy package name (if you are still using it):\n\n- Package: `@clawdbot/voice-call`\n- Vulnerable versions: `<= 2026.1.24`\n- Patched versions: none published under this package name; migrate to `@openclaw/voice-call`\n\n## Summary\n\nIn certain reverse-proxy / forwarding setups, webhook verification can be bypassed if untrusted forwarded headers are accepted.\n\n## Impact\n\nAn external party may be able to send voice-call webhook requests that are accepted as valid, which can result in spoofed webhook events being processed.\n\n## Root Cause\n\nSome deployments implicitly trusted forwarded headers (for example `Forwarded` / `X-Forwarded-*`) when determining request properties used during webhook verification. If those headers are not overwritten by a trusted proxy, a client can supply them directly and influence verification.\n\n## Resolution\n\nIgnore forwarded headers by default unless explicitly trusted and allowlisted in configuration. Keep any loopback-only development bypass restricted to local development only. Upgrade to a patched version.\n\nIf you cannot upgrade immediately, strip `Forwarded` and `X-Forwarded-*` headers at the edge so clients cannot supply them directly.\n\n## Fix Commit(s)\n\n- `a749db9820eb6d6224032a5a34223d286d2dcc2f`\n\n## Credits\n\nThanks `@0x5t` for reporting.","published":"2026-03-05T21:59:41.870Z","modified":"2026-09-19T03:30:55.864791178Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@openclaw/voice-call","fixedVersion":"2026.2.3"},{"ecosystem":"npm","name":"@clawdbot/voice-call","fixedVersion":null}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/a749db9820eb6d6224032a5a34223d286d2dcc2f","label":"openclaw/openclaw@a749db9"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28465.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-3m3q-x3gj-f79x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28465"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-voice-call-webhook-verification-bypass-via-forwarded-headers"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/a749db9820eb6d6224032a5a34223d286d2dcc2f"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:30:55.864791178Z"}}
