CVE-2025-12074 is an information exposure vulnerability classified under CWE-200, affecting the Context Blog WordPress theme developed by postmagthemes. The flaw exists in all versions up to and including 1.2.5, specifically within the 'context_blog_modal_popup' feature. This feature lacks sufficient access control checks, allowing unauthenticated attackers to retrieve content from posts that are intended to be restricted, such as password-protected, private, or draft posts. The vulnerability is exploitable remotely without requiring any authentication or user interaction, making it accessible to any attacker with network access to the affected WordPress site. The root cause is improper validation of post access permissions before including post content in the modal popup, leading to unauthorized data disclosure. While the vulnerability does not affect the integrity or availability of the system, it compromises confidentiality by exposing sensitive or unpublished content. No public exploits have been reported yet, but the vulnerability is publicly disclosed and assigned a CVSS 3.1 base score of 5.3, indicating a medium risk. The vulnerability affects a widely used content management system theme, which increases the potential attack surface. Organizations relying on the Context Blog theme for internal or sensitive communications are particularly vulnerable to data leakage. The lack of a patch at the time of disclosure necessitates immediate mitigation efforts to prevent exploitation.

The primary impact of CVE-2025-12074 is the unauthorized disclosure of sensitive information, which can lead to data breaches, loss of confidentiality, and potential reputational damage. For European organizations, especially those handling sensitive or regulated data (e.g., GDPR-protected personal data), this exposure could result in compliance violations and financial penalties. Attackers could leverage the vulnerability to access unpublished or internal content, potentially gaining insights into business operations, intellectual property, or strategic plans. Although the vulnerability does not allow modification or disruption of services, the confidentiality breach alone can have significant consequences, including targeted phishing, social engineering attacks, or competitive intelligence gathering. The ease of exploitation without authentication increases the risk of widespread scanning and automated attacks. Organizations using the Context Blog theme on public-facing WordPress sites are at higher risk, particularly in sectors such as media, government, education, and enterprises that publish sensitive content. The impact is amplified in countries with high adoption of WordPress and this theme, where attackers may focus their efforts.

1. Monitor the postmagthemes official channels and WordPress theme repositories for an official patch addressing CVE-2025-12074 and apply it promptly once available. 2. Until a patch is released, implement custom access control measures by modifying the 'context_blog_modal_popup' functionality to enforce strict permission checks, ensuring only authorized users can access password-protected, private, or draft posts. 3. Restrict public access to the modal popup feature via web application firewall (WAF) rules or server-side filtering to block suspicious or unauthorized requests targeting this functionality. 4. Conduct an audit of all WordPress sites using the Context Blog theme to identify and isolate vulnerable instances. 5. Educate content creators and administrators to avoid placing highly sensitive information in posts that might be exposed due to this vulnerability. 6. Employ security plugins that enhance WordPress access control and monitor for unusual access patterns. 7. Regularly back up site content and configurations to enable recovery in case of compromise. 8. Consider temporarily disabling or replacing the Context Blog theme with a secure alternative if immediate patching or mitigation is not feasible.
