The vulnerability CVE-2025-39594 affects Bob Arigato Autoresponder and Newsletter (bft-autoresponder) versions up to 2.7.2.4. It is a reflected cross-site scripting (XSS) flaw caused by improper neutralization of input during web page generation. This allows attackers to inject malicious scripts that execute in the context of the victim's browser, potentially leading to information disclosure, session hijacking, or other impacts. 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 impacts on confidentiality, integrity, and availability. No known exploits in the wild or patch information is currently available.

Successful exploitation of this reflected XSS vulnerability can lead to partial compromise of user confidentiality, integrity, and availability within the affected application context. Attackers may execute arbitrary scripts in victims' browsers, potentially stealing session tokens, redirecting users, or performing actions on their behalf. The vulnerability does not require privileges but does require user interaction. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and educate users about the risks of clicking suspicious links. Monitor vendor channels for updates and apply patches promptly once available.
