CVE-2025-23585 describes a reflected cross-site scripting (XSS) vulnerability in the CantonBolo Goo.gl Url Shorter application (versions up to 1.0.1). The issue is due to improper neutralization of input during web page generation, which allows attackers to inject malicious scripts that execute in the context of the victim's browser. The CVSS 3.1 base score is 7.1, indicating high severity, with attack vector network, low attack complexity, no privileges required, user interaction needed, scope changed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to data theft, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability. The reflected nature means the attack requires a victim to interact with a crafted link or page. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when interacting with links generated by the affected Goo.gl Url Shorter versions. Implementing web application firewall (WAF) rules to detect and block reflected XSS payloads may provide temporary mitigation.
