Security risk: 
Moderately critical 14\u2009\u2215\u200925 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon
Vulnerability: 
Access bypass
Affected versions: 
<7.95 || >=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5
Description: 

Drupal core provides a page that outputs the markup from phpinfo() to assist with diagnosing PHP configuration.

\n

If an attacker was able to achieve an XSS exploit against a privileged user, they may be able to use the phpinfo page to access sensitive information that could be used to escalate the attack.

\n

This vulnerability is mitigated by the fact that a successful XSS exploit is required in order to exploit it.

Solution: 

Install the latest version:

\n\n

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.
