CVE-2026-2924 is a stored cross-site scripting vulnerability in the Gutenverse – Ultimate WordPress FSE Blocks Addons & Ecosystem plugin. It affects versions up to 3.4.6 and is triggered via the 'imageLoad' parameter due to improper neutralization of input during web page generation (CWE-79). Authenticated users with contributor-level privileges or higher can inject arbitrary web scripts that execute in the context of other users viewing the injected pages. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability.

An attacker with contributor-level or higher privileges can exploit this vulnerability to inject malicious scripts into pages, potentially leading to unauthorized actions performed in the context of other users, theft of sensitive information, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider additional input validation or web application firewall rules to detect and block malicious payloads targeting the 'imageLoad' parameter. Monitor vendor channels for updates and apply patches promptly once available.
