The vulnerability CVE-2025-59585 in PenciDesign Penci Recipe (<= 4.0) is a DOM-based Cross-site Scripting (XSS) flaw caused by improper neutralization of input during web page generation. This allows an attacker to inject and execute malicious scripts in the victim's browser when they interact with crafted content. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, requiring low privileges and user interaction, with a scope change and limited impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The impact is rated medium due to the requirement of user interaction and low privileges, and the limited scope of the compromise.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or vendor advisory is provided, users should monitor for updates from PenciDesign and apply any official fixes when available. In the meantime, consider applying web application firewall (WAF) rules to detect and block suspicious input patterns related to DOM-based XSS if feasible.
