The Joan Boluda Embed documents shortcode plugin (versions up to 1.5) suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows an attacker with low privileges and requiring user interaction to inject malicious scripts that can lead to partial confidentiality, integrity, and availability impacts. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reflects network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with limited privileges to execute arbitrary scripts in the context of other users, potentially leading to partial disclosure of information, modification of data, or disruption of service. The vulnerability affects confidentiality, integrity, and availability to a limited extent. 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, users should consider restricting access to the affected shortcode functionality and applying input validation or sanitization measures where possible. Monitor official channels for updates and apply patches promptly once available.
