CVE-2025-1291 is a stored cross-site scripting vulnerability in the Kadence Blocks — Page Builder Toolkit for Gutenberg Editor WordPress plugin. It results from improper neutralization of input in the 'icon' parameter, allowing authenticated users with Contributor-level or higher privileges to inject arbitrary web scripts. These scripts persist in pages and execute in the context of any user viewing the affected content. The vulnerability affects all plugin versions up to and including 3.4.9. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or vendor advisory is currently provided, and no exploits are known in the wild.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the 'icon' parameter. These scripts execute in the context of users viewing the infected pages, potentially leading to unauthorized actions or data disclosure limited to the confidentiality and integrity impacts noted. There is no impact on availability. The vulnerability could be leveraged to compromise site users or administrators depending on the injected payload.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to restrict Contributor-level access to trusted users only. Review and sanitize any user-generated content involving the 'icon' parameter manually if possible. Monitor the vendor's communications for updates and apply patches promptly once available.
