The devfelixmoira Poll Builder plugin versions up to 1.3.5 contain a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users, potentially leading to partial confidentiality, integrity, and availability impacts. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope changed with low impact on confidentiality and integrity and low impact on availability.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of users interacting with the Poll Builder plugin, potentially leading to information disclosure, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability to a limited extent. The medium severity reflects these moderate impacts. No known active exploitation has been reported.

Patch status is not yet confirmed — no official fix or patch information is currently available. Users should monitor the vendor's advisory channels for updates regarding patches or official remediation. Until a fix is released, consider restricting access to the affected plugin or disabling it if feasible to reduce exposure. Avoid interacting with untrusted input in the Poll Builder plugin and apply standard web application security best practices where applicable.
