{"apiVersion":"1.0","identifier":"CVE-2026-62668","description":"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.","publishedAt":"2026-08-19T16:18:19","lastModifiedAt":"2026-08-19T19:17:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62668","cvssScore":9.4,"cvssVector":"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/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","epssProbability":0.0033,"riskScore":0.97,"affectedProduct":"Grav API Plugin","affectedVersions":"<1.0.6","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62668","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62668","en":"https://www.redsauce.net/en/cves/CVE-2026-62668","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62668","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62668","de":"https://www.redsauce.net/de/cves/CVE-2026-62668","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62668","el":"https://www.redsauce.net/el/cves/CVE-2026-62668"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62668"}}
