The NewsBlogger theme for WordPress is vulnerable to Cross-Site Request Forgery in versions 0.2.5.6 to 0.2.5.9. This is due to missing or incorrect nonce validation on the newsblogger_install_and_activate_plugin() function.
This makes it possible for unauthenticated attackers to upload arbitrary files and achieve remote code execution via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This is due to a reverted fix of CVE-2025-1305.
Not sure which version you run? Run a passive check — it reads public files only.
Remediation & mitigations
- Update to version 0.2.6, or a newer patched version
- Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
