Exploit maturity not defined.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

to version 2.44.3, 2.45.1 or higher.
Affected versions of this package are vulnerable to Improper Privilege Management during the handling of a cookie for user agent (browser) and user sessions identification. Although the cookie is managed according to best practices, it is accessible on subdomains of the instance, allowing an attacker to exploit this by providing a malicious link hosted on the subdomain.
This could lead to unauthorized access to the victim's account under certain conditions.
Note:
The exploit requires the victim to log in through the malicious link, and success is contingent upon the presence of an initial vulnerability on the subdomain, such as the attacker's ability to control DNS or an existing XSS vulnerability in an application hosted on the subdomain.
This vulnerability can be mitigated by preventing the setting of the __Secure-zitadel-useragent
cookie on subdomains of the instance, for example, within a Web Application Firewall (WAF).
