CVE-2025-7431 is a stored cross-site scripting vulnerability in the ajay Knowledge Base plugin for WordPress, present in all versions up to 2.3.1. The vulnerability is due to improper neutralization of input in the plugin slug setting, allowing authenticated users with administrator privileges to inject arbitrary web scripts. These scripts execute when any user accesses the affected pages. The vulnerability specifically impacts multi-site WordPress setups or installations where the unfiltered_html capability is disabled. The CVSS 3.1 base score is 4.4, reflecting a medium severity with network attack vector, high attack complexity, and requiring high privileges but no user interaction.

An attacker with administrator-level access on affected WordPress multi-site installations or those with unfiltered_html disabled can inject persistent malicious scripts via the plugin slug setting. These scripts execute in the context of users visiting the injected pages, potentially leading to information disclosure or session hijacking. The impact is limited by the requirement for administrator privileges and the specific environment conditions.

No official patch or fix is currently documented for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator access to trusted users only and consider disabling or avoiding use of the ajay Knowledge Base plugin in multi-site environments or where unfiltered_html is disabled. Monitor vendor channels for updates and apply patches promptly once released.
