The Issuu Panel product contains a CSRF vulnerability that enables stored XSS attacks. This affects all versions up to 2.1.1. The vulnerability allows an attacker to trick an authenticated user into submitting a forged request, potentially resulting in persistent malicious script injection. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute stored XSS payloads via CSRF, potentially leading to session hijacking, unauthorized actions, or other client-side impacts. The vulnerability affects confidentiality, integrity, and availability to a low degree but is considered high severity due to the combination of CSRF and stored XSS.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider implementing CSRF protections such as anti-CSRF tokens and input validation to mitigate risk. Monitor vendor communications for updates on patches or official fixes.
