CVE-2026-57359 is an unauthenticated Cross Site Scripting (XSS) vulnerability affecting ReviewX versions <= 2.3.10. The vulnerability allows remote attackers to inject and execute malicious scripts in the context of users interacting with the affected application. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or remediation information is currently provided.

Successful exploitation can lead to execution of arbitrary scripts in users' browsers, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data. The vulnerability does not require authentication, increasing the risk of exploitation. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider applying input validation and output encoding as temporary mitigations to reduce the risk of XSS.
