Vulnerability from github – Published: 2026-10-16 21:33 – Updated: 2026-10-16 21:33

Details

Incorrect permission assignment (CWE-732) in the standalone installer for EA Javelin Anticheat (versions 1.0.14329371, 1.0.14547437, 1.0.14789537, and 1.0.14940698) on Windows allows a local non-administrative user to elevate privileges to NT AUTHORITY\SYSTEM by modifying the EAAntiCheatService service configuration and executable path. This vulnerability requires non-standard manual execution of the standalone installer and does not affect standard game installations via the EA App and Steam. This issue is corrected in version 1.0.14940699 and later; service permissions automatically self-heal upon launching an integrated EA game title.

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.
