Summary

Duplicate Advisory: phpMyFAQ has stored XSS via | raw Filter in search.twig — html_entity_decode(strip_tags()) Bypass in Search Result Rendering

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-pqh6-8fxf-jx22. This link is maintained to preserve external references.

Original Description

phpMyFAQ before 4.1.2 contains a stored cross-site scripting vulnerability in search.twig where result.question and result.answerPreview are rendered with the raw filter, disabling autoescape protection. Attackers with FAQ editor privileges can inject HTML-entity-encoded payloads that bypass html_entity_decode(strip_tags()) processing in SearchController.php, executing arbitrary JavaScript in every visitor's browser context including administrators.

Severity

6.9 (Medium)

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.
