{"id":"CVE-2026-28454","details":"OpenClaw versions prior to 2026.2.2 fail to validate webhook secrets in Telegram webhook mode (must be enabled), allowing unauthenticated HTTP POST requests to the webhook endpoint that trust attacker-controlled JSON payloads. Remote attackers can forge Telegram updates by spoofing message.from.id and chat.id fields to bypass sender allowlists and execute privileged bot commands.","aliases":["GHSA-fhvm-j76f-qmjv"],"modified":"2026-04-10T05:41:12.643088Z","published":"2026-03-05T22:16:17.817Z","references":[{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fhvm-j76f-qmjv"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-unauthenticated-telegram-webhook"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/5643a934799dc523ec2ef18c007e1aa2c386b670"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/633fe8b9c17f02fcc68ecdb5ec212a5ace932f09"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/ca92597e1f9593236ad86810b66633144b69314d"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"95cd2210f93d6ab2acc5e29dbad6065294365863"},{"fixed":"3cbcba10cf30c2ffb898f0d8c7dfb929f15f8930"},{"fixed":"5643a934799dc523ec2ef18c007e1aa2c386b670"},{"fixed":"633fe8b9c17f02fcc68ecdb5ec212a5ace932f09"},{"fixed":"ca92597e1f9593236ad86810b66633144b69314d"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2026.2.2"}]}}],"versions":["v0.1.0","v0.1.1","v0.1.2","v0.1.3","v1.0.4","v1.1.0","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v2.0.0-beta1","v2.0.0-beta2","v2.0.0-beta3","v2.0.0-beta4","v2.0.0-beta5","v2026.1.10","v2026.1.11","v2026.1.11-1","v2026.1.11-2","v2026.1.11-3","v2026.1.12","v2026.1.12-2","v2026.1.13","v2026.1.14-1","v2026.1.15","v2026.1.16-2","v2026.1.20","v2026.1.21","v2026.1.22","v2026.1.23","v2026.1.24","v2026.1.24-1","v2026.1.29","v2026.1.30","v2026.1.5","v2026.1.5-1","v2026.1.5-2","v2026.1.5-3","v2026.1.8","v2026.1.9","v2026.2.1","v2026.2.12","v2026.2.13","v2026.2.2","v2026.2.3","v2026.2.6","v2026.2.6-1","v2026.2.6-2","v2026.2.6-3","v2026.2.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28454.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
