CVE-2026-67921Public exploitNetwork attack vector

Remote code execution via CSRF misconfiguration

Published Aug 18, 2026 · Updated Aug 20, 2026

Cross-site request forgery in Halo CMS 2.25.4 and earlier allows remote attackers to execute arbitrary code through crafted requests. The public CVE record names CorsConfigurer.java and CsrfConfigurer.java as the affected components, but it does not disclose the specific request-validation error or state-changing endpoint. Exploitation requires a victim to interact with attacker-controlled content while an applicable session is active, and successful requests can compromise application code and data without a reported service interruption.
