CVE-2025-23760 describes a Stored Cross-site Scripting vulnerability in the Alex Volkov Chatter application (versions <= 1.0.1). The issue stems from improper input neutralization during web page generation, enabling attackers to inject malicious scripts that persist and execute in the context of other users. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability. No patch or official fix has been documented, and no known exploits are currently reported.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to partial compromise of confidentiality, integrity, and availability of the affected system or user data. The CVSS score indicates a high severity with impacts on all three security properties, but exploitation requires user interaction. No known active exploitation has been reported.
