The JetBlocks for Elementor plugin suffers from a stored XSS vulnerability due to improper neutralization of input during web page generation (CWE-79). This allows authenticated attackers with Contributor-level privileges or above to inject arbitrary JavaScript into placeholder parameters. These scripts execute in the context of users who visit the compromised pages, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to 1.3.12. No vendor advisory or patch links are currently available, and the plugin is not a cloud service, so remediation depends on vendor updates or user action.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who view the infected pages, potentially leading to theft of sensitive information or unauthorized actions performed on behalf of users. The vulnerability does not impact availability but compromises confidentiality and integrity to a limited extent as indicated by the CVSS vector (C:L/I:L/A:N). No known exploits are reported 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 disabling or removing the JetBlocks for Elementor plugin if possible. Monitor for updates from Crocoblock regarding patches or security advisories.
