The vulnerability CVE-2024-51805 in yonisink yPHPlista (<= 1.1.1) is a stored cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that 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, requiring privileges and user interaction, with scope changed and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to partial disclosure of information, modification of data, or disruption of service. The impact is rated medium based on the CVSS score of 6.5. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor channels for updates and apply patches promptly once available.
