CVE-2026-75830: External Control of File Name or Path in getgrav grav
grav-plugin-api (getgrav/grav-plugin-api) versions >= 1.0.0-beta.10 and <= 1.0.14 contain a path traversal vulnerability in the PagesController::batchCopy() method. An incomplete fix for GHSA-qjq4-jp55-4mx2 left the user-controlled 'suffix' parameter (via POST /api/v1/pages/batch) unvalidated. An authenticated user with the api.pages.write permission (editor-level, not super-admin) can supply path traversal sequences (e.g. /../../../) in the suffix parameter to escape the intended user/pages/ directory and write attacker-controlled page content and page media to arbitrary filesystem locations writable by the web server process. The vulnerability is fixed in 1.0.15.
AI Analysis
Technical Summary
grav-plugin-api (getgrav/grav-plugin-api) versions >=1.0.0-beta.10 and <=1.0.14 contain a path traversal vulnerability in the PagesController::batchCopy() method. The vulnerability arises from an incomplete fix for a previous issue (GHSA-qjq4-jp55-4mx2) that left the user-controlled 'suffix' parameter unvalidated. An authenticated user with api.pages.write permission (editor-level) can supply path traversal sequences (e.g., /../../../) in the suffix parameter via POST /api/v1/pages/batch to escape the intended user/pages/ directory. This enables writing attacker-controlled page content and media to arbitrary filesystem locations writable by the web server process. The vulnerability is fixed in version 1.0.15.
Potential Impact
An attacker with authenticated editor-level access can write arbitrary files to locations outside the intended directory, potentially leading to unauthorized file creation or modification on the server. This could be leveraged to deploy malicious content or disrupt site functionality. The vulnerability does not require super-admin privileges but does require api.pages.write permission.
Mitigation Recommendations
Upgrade grav-plugin-api to version 1.0.15 or later, where this path traversal vulnerability is fixed. Until upgrading, restrict api.pages.write permissions to trusted users only. Patch status is not explicitly stated in the vendor advisory, but the fix is confirmed in version 1.0.15.
