The vulnerability CVE-2026-27059 in PenciDesign's Penci Recipe plugin is a DOM-based Cross-site Scripting issue caused by improper input neutralization during web page generation. It affects versions up to 4.1 and allows an attacker with low privileges to execute scripts in the context of the victim's browser, contingent on user interaction. The CVSS 3.1 score is 6.5, reflecting network attack vector, low attack complexity, required privileges, user interaction, and impacts on confidentiality, integrity, and availability. No patch or official remediation has been documented in the provided data.

Successful exploitation could lead to partial compromise of confidentiality, integrity, and availability of the affected system or user data through execution of arbitrary scripts in the victim's browser. This may enable actions such as session hijacking or unauthorized actions performed on behalf of the user. However, exploitation requires user interaction and low-level privileges, limiting the ease of attack. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
