CVE-2025-14057 is a stored cross-site scripting vulnerability (CWE-79) in the Multi-column Tag Map plugin for WordPress. The flaw exists due to improper neutralization of input during web page generation, specifically in the admin settings interface. Authenticated administrators can inject malicious scripts that persist and execute in the context of users viewing the injected pages. This vulnerability impacts multi-site WordPress setups and installations with unfiltered_html disabled. The CVSS 3.1 vector indicates network attack vector, high attack complexity, high privileges required, no user interaction, and a scope change with low confidentiality and integrity impact and no availability impact.

An attacker with administrator-level access can inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the context of users accessing the injected pages, potentially leading to data theft or session hijacking. The vulnerability is limited to multi-site WordPress installations or those with unfiltered_html disabled, reducing the overall attack surface. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available. Until a patch is released, restrict administrator access to trusted users only and consider disabling or removing the Multi-column Tag Map plugin in multi-site environments or where unfiltered_html is disabled. Monitor vendor channels for updates and apply official fixes once available.
