{"id":"CVE-2026-29606","summary":"OpenClaw \u003c 2026.2.14 - Webhook Signature Verification Bypass via ngrok Loopback Compatibility","details":"OpenClaw versions prior to 2026.2.14 contain a webhook signature-verification bypass in the voice-call extension that allows unauthenticated requests when the tunnel.allowNgrokFreeTierLoopbackBypass option is explicitly enabled. An external attacker can send forged requests to the publicly reachable webhook endpoint without a valid X-Twilio-Signature header, resulting in unauthorized webhook event handling and potential request flooding attacks.","aliases":["GHSA-c37p-4qqg-3p76"],"modified":"2026-08-12T03:51:37.556306542Z","published":"2026-03-05T22:00:05.680Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29606.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29606.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-c37p-4qqg-3p76"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29606"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-webhook-signature-verification-bypass-via-ngrok-loopback-compatibility"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/ff11d8793b90c52f8d84dae3fbb99307da51b5c9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"b5ab92eef4e4f6099c98817e0917c99ec9e03045"},{"fixed":"ff11d8793b90c52f8d84dae3fbb99307da51b5c9"}],"database_specific":{"cpe":"cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2026.2.14"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2026.2.13","v2026.2.12","v2026.2.9","v2026.2.6-3","v2026.2.6-2","v2026.2.6-1","v2026.2.6","v2026.2.3","v2026.2.2","v2026.2.1","v2026.1.30","v2026.1.29","v2026.1.24-1","v2026.1.24","v2026.1.23","v2026.1.22","v2026.1.21","v2026.1.20","v2026.1.16-2","v2026.1.15","v2026.1.14-1","v2026.1.13","v2026.1.12-2","v2026.1.12","v2026.1.11-3","v2026.1.11-2","v2026.1.11-1","v2026.1.11","v2026.1.10","v2026.1.9","v2026.1.8","v2026.1.5-3","v2026.1.5-2","v2026.1.5-1","v2026.1.5","v2.0.0-beta5","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29606.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
