CVE-2025-8560 is a stored cross-site scripting vulnerability in the ghosttoast FancyTabs WordPress plugin affecting all versions up to and including 1.1.0. The vulnerability is due to improper neutralization of input in the 'title' parameter, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute when other users access the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges, no user interaction, and impacts confidentiality and integrity with no availability impact.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to unauthorized actions such as session hijacking or data theft limited to confidentiality and integrity impacts. There is no indication of availability impact. No known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the FancyTabs plugin if possible. Monitor official ghosttoast or WordPress plugin repositories for updates addressing this vulnerability.
