Title
Epsilon Framework Themes (Various Versions) - Unauthenticated Plugin Activation/Deactivation
Summary
The Brilliance <= 1.2.7, Activello <= 1.4.0, and Newspaper X <= 1.3.1 themes for WordPress are vulnerable to Plugin Activation/Deactivation. This is due to the 'activello_activate_plugin' and 'activello_deactivate_plugin' functions in the 'inc/welcome-screen/class-activello-welcome.php' file missing capability and security checks/nonces. This makes it possible for unauthenticated attackers to activate and deactivate arbitrary plugins installed on a vulnerable site.

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.
