Last modified

CVE-2025-5769 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. The authentication endpoint does not properly encode user-supplied input before rendering it within the web page. This lack of output encoding allows an attacker to inject malicious JavaScript payloads into the authentication flow, which are then executed by the victim's browser. By exploiting this vulnerability, an attacker can redirect the user's browser to a malicious website, modify the content of the web page displayed to the user, or exfiltrate information from the browser. EPSS estimates a 0.17% chance of exploitation in the next 30 days.

Description

The authentication endpoint does not properly encode user-supplied input before rendering it within the web page. This lack of output encoding allows an attacker to inject malicious JavaScript payloads into the authentication flow, which are then executed by the victim's browser. By exploiting this vulnerability, an attacker can redirect the user's browser to a malicious website, modify the content of the web page displayed to the user, or exfiltrate information from the browser. However, due to the implementation of the httpOnly flag on session-related sensitive cookies, session hijacking and similar attacks are not possible.
