CVE-2025-32558: 
WordPress vulnerability analysis and mitigation

A SQL Injection vulnerability (CVE-2025-32558) was discovered in the WordPress Duplicate Title Checker plugin affecting versions up to 1.2. The vulnerability was reported on December 15, 2024, by João Pedro S. Alcântara (Kinorth) and was publicly disclosed on April 9, 2025. This security flaw allows for Blind SQL Injection attacks in the ketanajani Duplicate Title Checker plugin (Patchstack).

The vulnerability has been assigned a CVSS v3.1 base score of 8.5 (HIGH) with the following vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L. The flaw is categorized as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The vulnerability can be exploited by users with Subscriber-level privileges (Patchstack).

This vulnerability is considered highly dangerous and is expected to become mass exploited. It could allow malicious actors to directly interact with the database, potentially leading to unauthorized access to sensitive information. The software is considered abandoned, as it hasn't been updated for over a year, increasing the risk for users (Patchstack).

The vulnerability requires low attack complexity and can be exploited remotely. It requires low privileges (Subscriber level) to execute, and no user interaction is needed for exploitation. The software's abandoned status increases the likelihood of successful exploitation as no official patches are expected (Patchstack).

As no official fix is available, users are strongly advised to remove and replace the plugin immediately. Patchstack has issued a virtual patch to mitigate this issue by blocking potential attacks until an official fix becomes available. Note that merely deactivating the software does not remove the security threat unless a virtual patch is deployed (Patchstack).
