CVE-2025-23663 describes a reflected Cross-site Scripting (XSS) vulnerability in the Contexto product by Adrian Vaquez, affecting versions up to 1.0. The issue is caused by improper neutralization of input during web page generation, which allows attackers to inject malicious scripts that execute in users' browsers when they visit crafted URLs or web pages. This vulnerability requires no privileges and has low attack complexity but requires user interaction. It impacts confidentiality, integrity, and availability to a limited extent as indicated by the CVSS vector. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of a victim's browser session. This can lead to theft of sensitive information, session hijacking, or other malicious actions that compromise user data and application integrity. The CVSS score of 7.1 reflects a high impact on confidentiality, integrity, and availability, though exploitation requires user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users and administrators should consider applying input validation and output encoding controls where possible, and avoid clicking on suspicious links that could trigger reflected XSS. Monitor vendor communications for updates on patches or official mitigations.
