CVE-2025-67565: 
WordPress vulnerability analysis and mitigation

CVE-2025-67565 is a Sensitive Data Exposure vulnerability in the Rehub WordPress theme developed by Sizam. Classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), it allows unauthenticated remote attackers to retrieve embedded sensitive data from affected installations. The vulnerability affects all Rehub theme versions up to and including 19.9.9.1. It was published on December 9, 2025, and assigned by Patchstack. It carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly, Patchstack).

The root cause is classified as CWE-497 — Exposure of Sensitive System Information to an Unauthorized Control Sphere — meaning the Rehub theme inadvertently exposes sensitive system or configuration data in a context accessible to unauthorized parties. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any remote attacker. The associated attack pattern is CAPEC-170 (Web Application Fingerprinting), suggesting the exposed data may include version strings, configuration details, or other system metadata that could aid further attacks. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation results in a low-level confidentiality impact, with no effect on integrity or availability. An unauthenticated attacker can retrieve embedded sensitive data — such as system configuration details, version information, or internal metadata — from vulnerable Rehub-themed WordPress sites. While the direct impact is limited, the exposed information could facilitate reconnaissance and enable more targeted follow-on attacks against the affected WordPress installation (Feedly).

No public exploit code or active in-the-wild exploitation has been reported for CVE-2025-67565 as of the available data. The EPSS score is approximately 0.039%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Despite the low exploitation probability, the zero-authentication requirement and low complexity make it accessible to any opportunistic attacker scanning for vulnerable WordPress themes (Feedly).

1. Reconnaissance: Use tools such as WPScan or Shodan to identify WordPress sites running the Rehub theme at versions 19.9.9.1 or earlier.
2. Identify exposed endpoint: Probe the target site for publicly accessible endpoints or responses that leak sensitive system information (e.g., theme version strings, configuration data embedded in page source or API responses).
3. Send unauthenticated request: Issue a standard HTTP GET request to the identified endpoint — no credentials or special headers required.
4. Extract sensitive data: Parse the server response to retrieve embedded sensitive information (e.g., internal paths, version details, configuration metadata) that can be used for further reconnaissance or targeted exploitation (Feedly, Patchstack).

• Network: Unusual or repeated unauthenticated HTTP GET requests to theme-specific endpoints on WordPress sites running Rehub; scanning traffic from automated tools (e.g., WPScan user-agent strings) targeting theme version disclosure endpoints.
• Logs: Web server access logs showing high-frequency requests to Rehub theme files or REST API endpoints from single or rotating IP addresses without authentication headers.
• File System: No file system changes are expected from read-only data exposure exploitation; however, monitor for subsequent unauthorized file access or modification attempts following reconnaissance activity.

Users should update the Rehub theme to a version beyond 19.9.9.1 as soon as a patched release is made available by the vendor (Sizam). In the interim, site administrators should consider restricting access to sensitive theme endpoints via web application firewall (WAF) rules or server-level access controls. Monitoring web server logs for unusual unauthenticated requests targeting theme-specific paths is also recommended as a detection measure (Patchstack).
