CVE-2026-75830: External Control of File Name or Path in getgrav grav
A path traversal vulnerability exists in grav-plugin-api versions from 0 up to 1.0.14 in the PagesController::batchCopy() method. Authenticated users with editor-level permissions can exploit this flaw by supplying crafted path traversal sequences in the 'suffix' parameter to write arbitrary files outside the intended directory. This vulnerability allows unauthorized file writes to locations writable by the web server. The issue is fixed in version 1.0.15.
AI Analysis
Technical Summary
grav-plugin-api (getgrav/grav-plugin-api) versions >= 0 and < 1.0.15 contain a path traversal vulnerability in the PagesController::batchCopy() method. An incomplete fix for a prior advisory left the user-controlled 'suffix' parameter unvalidated, allowing authenticated users with api.pages.write permission to supply path traversal sequences (e.g., /../../../) via POST /api/v1/pages/batch. This enables writing attacker-controlled page content and media to arbitrary filesystem locations writable by the web server process. The vulnerability is resolved in version 1.0.15.
Potential Impact
An authenticated user with editor-level permissions can exploit this vulnerability to write arbitrary files outside the intended directory, potentially leading to unauthorized modification or addition of content and media on the server. This could compromise the integrity of the system or enable further attacks depending on the writable locations.
Mitigation Recommendations
Upgrade grav-plugin-api to version 1.0.15 or later where this vulnerability is fixed. No other mitigation is indicated by the vendor advisory.
