Vulnerability from drupal

Published

Summary

Details

Node view permissions module enables permissions "View own content" and "View any content" for each content type on permissions page
The module doesn't sufficiently handle the case where a user is cancelled and their content is reassigned to the anonymous user.
This vulnerability is mitigated by the fact that only private contents where anonymous should not have view access are affected, and only if a node was reassigned to the anonymous user.

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.
