Attack Vectors

Remove Post Type Slug (slug: remove-post-type-slug) has a Medium-severity Cross-Site Request Forgery (CSRF) vulnerability (CVSS 4.3, CVE: CVE-2025-14167) affecting versions up to and including 1.0.2.

An unauthenticated attacker cannot directly “log in,” but they can attempt to trick a site administrator into triggering a forged request—commonly by clicking a link, visiting a webpage, or interacting with content while already authenticated to the WordPress admin area. If successful, the attacker can submit a request that changes the plugin’s settings without the administrator intending to do so.

Because this attack relies on normal user behavior (an admin being logged in and then being socially engineered), it is especially relevant for organizations where multiple staff, agencies, or vendors have administrative access, or where administrators routinely review external links as part of marketing and content workflows.

Security Weakness

The root issue is incorrect nonce validation logic in Remove Post Type Slug. The validation uses an OR (||) condition rather than the expected AND (&&), which can cause the security check to fail in a way that still permits the settings update request to proceed under conditions where it should be rejected.

In practical business terms, this means the plugin’s “are you allowed to change settings?” check can be bypassed through a forged request when an administrator is induced to perform an action that submits or triggers that request.

At the time of the referenced advisory, there is no known patch available. This increases risk because “wait for an update” may not be an acceptable strategy depending on your compliance obligations and exposure.

Technical or Business Impacts

The stated impact is the ability to modify the plugin’s post type slug removal settings. While the CVSS score indicates limited integrity impact (I:L) and no direct confidentiality or availability impact, configuration changes can still create meaningful downstream business risk.

Business impacts may include unplanned changes to URL structures and content behavior that affect marketing performance and governance—such as SEO volatility, broken campaign links, incorrect landing page paths, analytics attribution drift, and increased operational workload for marketing and web teams. For regulated organizations, unintended configuration changes may also complicate change management controls and audit readiness.

Recommended action: since no patch is known, assess whether Remove Post Type Slug is business-critical. If it is not essential, the most risk-reducing option may be to uninstall and replace it. If it must remain in place temporarily, reduce exposure by limiting administrator accounts, tightening operational processes around admin browsing/clicking behavior, and increasing monitoring for unexpected settings changes.
