CVE-2025-9353 is a stored cross-site scripting vulnerability in the Themify Builder WordPress plugin affecting all versions up to 7.6.9. The issue arises from improper neutralization of input during web page generation, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary scripts. These scripts execute in the context of users viewing the compromised pages. The vulnerability was partially addressed in version 7.6.9, but no complete patch or remediation details are provided. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impacts on confidentiality and integrity with no availability impact.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages, which execute when other users view those pages. This can lead to unauthorized actions or data exposure within the context of affected users. The vulnerability impacts confidentiality and integrity but does not affect availability. No known exploits in the wild have been reported to date.

The vulnerability was partially patched in version 7.6.9 of Themify Builder; however, no full fix or official patch advisory is available. Users should upgrade to version 7.6.9 or later if available and monitor vendor communications for a complete fix. Until a full patch is released, restrict Contributor-level access to trusted users only and consider additional input validation or output escaping controls at the application or web server level. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
