CVE-2026-8897 is a stored cross-site scripting vulnerability in the vincentastolfi Shortcode Buddy WordPress plugin. It arises from improper neutralization of input during web page generation (CWE-79), specifically in shortcode attributes. Authenticated attackers with contributor-level permissions or above can inject arbitrary scripts that persist in pages and execute in the context of users viewing those pages. The vulnerability affects all versions up to and including 0.1.9.5. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impact on confidentiality and integrity but not availability. No official patch or vendor advisory is currently available.

An attacker with contributor-level access or higher can inject malicious JavaScript code into pages via shortcode attributes. This code executes in the browsers of users who view the infected pages, potentially leading to session hijacking, data theft, or other client-side attacks. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known active exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider removing or disabling the Shortcode Buddy plugin if possible. Monitor for updates from the vendor or security community regarding patches or workarounds.
