CVE-2026-62668: CWE-918: Server-Side Request Forgery (SSRF) in getgrav grav
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.
AI Analysis
Technical Summary
The Grav API Plugin's WebhookController.php accepts webhook URLs after only FILTER_VALIDATE_URL syntax validation, which is insufficient to prevent malicious URLs. Additionally, WebhookDispatcher.php initializes cURL without restrictions on allowed protocols (CURLOPT_PROTOCOLS or CURLOPT_REDIR_PROTOCOLS), enabling SSRF attacks. An attacker with api.webhooks.write privileges can exploit this to send crafted requests to file, dict, gopher, private-network, or link-local targets, potentially retrieving sensitive local files or pivoting to internal or cloud metadata services. This vulnerability is addressed in version 1.0.6 of the plugin.
Potential Impact
An attacker with api.webhooks.write permissions can exploit this SSRF vulnerability to access internal network resources, retrieve local files, and interact with cloud metadata endpoints. This can lead to unauthorized data disclosure and potential further compromise of internal systems. The CVSS 4.0 score of 9.4 indicates a critical severity with high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
This vulnerability is fixed in Grav API Plugin version 1.0.6. Users should upgrade to version 1.0.6 or later to remediate the issue. No other official remediation or temporary fixes are indicated. Until upgrading, restrict api.webhooks.write permissions to trusted users only.
