{"id":"CVE-2026-62668","summary":"Grav API Plugin: Webhook SSRF via Unrestricted cURL Protocols","details":"Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, the Grav API plugin WebhookController.php accepts webhook URLs after only FILTER_VALIDATE_URL syntax validation, and WebhookDispatcher.php initializes cURL without CURLOPT_PROTOCOLS or CURLOPT_REDIR_PROTOCOLS restrictions. An account with api.webhooks.write can submit file, dict, gopher, private-network, or link-local targets, retrieve local files and delivery response bodies, and pivot requests to internal services or cloud metadata endpoints. This issue is fixed in version 1.0.6.","aliases":["CVE-2026-62234","GHSA-58q8-f7v4-w2vf"],"modified":"2026-08-21T03:46:54.776599687Z","published":"2026-08-19T15:29:24.452Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62668.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://github.com/getgrav/grav-plugin-api/releases/tag/1.0.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62668.json"},{"type":"ADVISORY","url":"https://github.com/getgrav/grav/security/advisories/GHSA-58q8-f7v4-w2vf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62668"},{"type":"FIX","url":"https://github.com/getgrav/grav-plugin-api/commit/dfcc947f0d6758772caac290c68fe8d4c4a4874e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getgrav/grav","events":[{"introduced":"0"},{"fixed":"c22d77d2ec2a9202d9f005f4ceda9c1483921286"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.0.4"}],"source":"AFFECTED_FIELD"}},{"type":"GIT","repo":"https://github.com/getgrav/grav-plugin-api","events":[{"introduced":"0"},{"fixed":"dfcc947f0d6758772caac290c68fe8d4c4a4874e"},{"fixed":"fe5146a3efeb39d1f405499188e5270bc002b0a6"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["2.0.3","2.0.2","2.0.1","1.7.53","1.7.52","1.7.51","1.7.39.1","1.7.39","1.7.38","1.7.37.1","1.7.37","1.7.36","1.7.35","1.7.34","1.7.33","1.7.32","1.7.31","1.7.30","1.7.29.1","1.7.29","1.7.28","1.7.27.1","1.7.27","1.7.26.1","1.7.26","1.7.25","1.7.24","1.7.23","1.7.22","1.7.21","1.7.20","1.7.19","1.7.18","1.7.17","1.7.16","1.7.15","1.7.14","1.7.13","1.7.12","1.7.10","1.7.9","1.7.8","1.7.7","1.7.6","1.7.5","1.7.4","1.7.3","1.7.1","1.7.0","1.7.0-rc.20","1.7.0-rc.19","1.7.0-rc.18","1.7.0-rc.17","1.7.0-rc.15","1.7.0-rc.14","1.7.0-rc.13","1.7.0-rc.12","1.7.0-rc.10","1.7.0-rc.9","1.7.0-rc.8","1.7.0-rc.7","1.7.0-rc.6","1.7.0-rc.5","1.7.0-rc.4","1.7.0-rc.3","1.7.0-rc.2","1.7.0-rc.1","1.7.0-beta.10","1.7.0-beta.9","1.7.0-beta.8","1.7.0-beta.7","1.7.0-beta.6","1.7.0-beta.5","1.7.0-beta.4","1.7.0-beta.3","1.7.0-beta.2","1.7.0-beta.1","1.6.0-rc.4","1.6.0-rc.3","1.6.0-rc.2","1.6.0-rc.1","1.6.0-beta.8","1.6.0-beta.7","1.6.0-beta.6","1.6.0-beta.5","1.6.0-beta.2","1.6.0-beta.1","1.5.0-rc.1","1.5.0-beta.2","1.5.0-beta.1","1.3.0-rc.5","1.3.0-rc.4","1.3.0-rc.3","1.3.0-rc.1","1.2.0-rc.3","1.2.0-rc.2","1.2.0-rc.1","1.1.9-rc.3","1.1.9-rc.2","1.1.9-rc.1","1.1.0-rc.3","1.1.0-rc.2","1.1.0-rc.1","1.1.0-beta.5","1.1.0-beta.4","1.1.0-beta.3","1.1.0-beta.2","1.1.0-beta.1","0.9.19","0.9.18","0.9.17","0.9.16","0.9.15","0.9.14","0.9.13","0.9.12","0.9.11","0.9.10","0.9.9","0.9.8","0.9.7","0.9.6","0.9.5","0.9.4","0.9.3","0.9.2","0.9.0","0.8.0","1.0.5","1.0.4","1.0.3","1.0.2","1.0.1","1.0.0","1.0.0-rc.16","1.0.0-rc.15","1.0.0-rc.14","1.0.0-rc.13","1.0.0-rc.12","1.0.0-rc.11","1.0.0-rc.10","1.0.0-rc.9","1.0.0-rc.8","1.0.0-rc.7","1.0.0-rc.6","1.0.0-rc.5","1.0.0-rc.4","1.0.0-rc.3","1.0.0-rc.2","1.0.0-rc.1","1.0.0-beta.17","1.0.0-beta.16","1.0.0-beta.15","1.0.0-beta.14","1.0.0-beta.13","1.0.0-beta.12","1.0.0-beta.11","1.0.0-beta.10","1.0.0-beta.9","1.0.0-beta.8","1.0.0-beta.7","1.0.0-beta.6","1.0.0-beta.5","1.0.0-beta.4","1.0.0-beta.3","1.0.0-beta.2","1.0.0-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-62668.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"}]}
