Title

Page Builder: KingComposer < 2.9.4 - Authorization Bypass due to Improper Access Control

Summary

The Page Builder: KingComposer plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 2.9.3. This is due to a security nonce being leaked in the '/wp-admin/index.php' page. This makes it possible for authenticated attackers to change arbitrary WordPress options, delete arbitrary files/folders, and inject arbitrary content.

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.
