{"id":"GHSA-8288-jpqp-95fx","summary":"Duplicate Advisory: OpenClaw has Bypass in Webhook Rate Limiting via Pre-Authentication Secret Validation","details":"### Duplicate Advisory\nThis advisory has been withdrawn because CVE-2026-34508 has been rejected as a duplicate of CVE-2026-34505. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.3.12 applies rate limiting only after webhook authentication succeeds, allowing attackers to bypass rate limits and brute-force webhook secrets without triggering 429 responses. Attackers can repeatedly guess invalid secrets to discover valid credentials and subsequently submit forged Zalo webhook traffic.","aliases":["CVE-2026-34508"],"modified":"2026-04-07T18:23:57.475746Z","published":"2026-03-31T12:31:36Z","withdrawn":"2026-04-07T18:04:56Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-04-07T18:04:56Z","nvd_published_at":"2026-03-31T12:16:30Z","cwe_ids":["CWE-307"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-5m9r-p9g7-679c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34508"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-webhook-rate-limiting-bypass-via-pre-authentication-secret-validation-2"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.3.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-8288-jpqp-95fx/GHSA-8288-jpqp-95fx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/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/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"}]}
