The vulnerability CVE-2025-31467 in the miro.mannino Flickr Photostream plugin is a reflected cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. It affects versions up to 3.1.8 and allows an attacker to inject malicious scripts that execute when a user interacts with crafted input, potentially compromising user data and session integrity. The CVSS v3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data. The reflected nature means the attack requires user interaction, such as clicking a crafted link. No known exploits in the wild have been reported.
