Low risk27th percentile - higher than 27% of all known CVEs
Summary
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.
Risk Assessment
The risk includes the possibility of remote code execution on the WordPress site, potentially leading to full compromise of the website and server.
Recommendation
Update the NewsBlogger theme to the latest patched version immediately and inform administrators about the risk of clicking suspicious links.
