CVE-2026-62234: Server-Side Request Forgery (SSRF) in getgrav grav
A Server-Side Request Forgery (SSRF) vulnerability exists in Grav before version 2.0.4. Authenticated users with api.webhooks.write permission can create webhooks using unsafe protocols such as file://, dict://, or gopher://. This allows triggering webhook events that may read local files, access process information, or interact with internal services. The vulnerability has a high severity score of 8.4.
AI Analysis
Technical Summary
Grav versions prior to 2.0.4 do not properly restrict the protocols allowed in webhook dispatch URLs. This flaw enables authenticated users with the api.webhooks.write permission to create webhooks that use potentially dangerous protocols like file://, dict://, or gopher://. When these webhook events are triggered, they can be exploited to perform Server-Side Request Forgery (SSRF) attacks, allowing attackers to read local files, gather process information, or pivot to internal network services. The vulnerability is identified as CVE-2026-62234 with a CVSS 4.0 score of 8.4, indicating a high severity risk.
Potential Impact
Successful exploitation allows attackers with limited authenticated permissions to perform SSRF attacks, potentially leading to unauthorized local file access, exposure of process information, and internal network pivoting. This can compromise the confidentiality and integrity of the affected system.
Mitigation Recommendations
A fix is available in Grav version 2.0.4 that restricts allowed protocols in webhook URLs. Users should upgrade to version 2.0.4 or later to remediate this vulnerability. No other official remediation guidance is provided. Patch status is confirmed by the affectedVersions data indicating versions before 2.0.4 are vulnerable.
