CVE-2025-5769: Authentication endpoint stored cross-site scripting

CVE-2025-5769 · Severity: medium · CVSS 6.1 · Published 2026-11-03

An authentication endpoint fails to properly encode user input before displaying it in web pages, allowing attackers to inject malicious JavaScript code. When a victim visits a crafted link, the attacker's code runs in their browser, potentially redirecting them to phishing sites or stealing sensitive information displayed on the page. However, the impact is limited because the application protects session cookies with security flags that prevent session theft.

Technical details

The vulnerability is a stored or reflected cross-site scripting (XSS) flaw in an authentication endpoint caused by insufficient output encoding of user-supplied input. An attacker can inject JavaScript payloads that execute in the victim's browser when the page is rendered; this enables credential harvesting, content manipulation, or information exfiltration. Session hijacking is mitigated by httpOnly cookie flags, limiting the attack scope.
