CVE-2026-62668
CriticalCVSS 9.4Summary
Vulnerability in Grav API Plugin (plugin for Grav CMS) before version 1.0.6. 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. Fixed in version 1.0.6.
Risk Assessment
An attacker with appropriate permissions can access local files, internal services, or cloud metadata, potentially leading to sensitive data leakage or privilege escalation.
Recommendation
Update Grav API Plugin to version 1.0.6 or later.
