{"id":"GHSA-r4c2-gq3j-7rpj","summary":"Duplicate Advisory: OpenClaw: Telegram Webhook Missing Guess Rate Limiting Enables Brute-Force Guessing of Weak Webhook Secret","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-vcx4-4qxg-mfp4. This link is maintained to preserve external references.\n\n## Original Description\nOpenClaw before 2026.3.25 contains a missing rate limiting vulnerability in Telegram webhook authentication that allows attackers to brute-force weak webhook secrets. The vulnerability enables repeated authentication guesses without throttling, permitting attackers to systematically guess webhook secrets through brute-force attacks.","modified":"2026-04-18T01:06:13.175176Z","published":"2026-04-10T00:30:30Z","withdrawn":"2026-04-18T00:45:07Z","database_specific":{"cwe_ids":["CWE-307"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-18T00:45:07Z","nvd_published_at":"2026-04-09T22:16:31Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-vcx4-4qxg-mfp4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35628"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/c2c136ae9517ddd0789d742a0fdf4c10e8c729a7"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-brute-force-attack-via-missing-telegram-webhook-rate-limiting"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"2026.3.24"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-r4c2-gq3j-7rpj/GHSA-r4c2-gq3j-7rpj.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/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"}]}
