Title

grav-plugin-api before 1.0.15 Path Traversal via batchCopy

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. 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.

Severity

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
