Summary

CVE-2022-0899 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Draftpress Header Footer Code Manager. Its CVSS base score is 6.1 (Medium).

Deeper analysis

The Header Footer Code Manager WordPress plugin before version 1.1.24 is affected by a reflected cross-site scripting vulnerability (CWE-79). The root cause is a failure to escape generated URLs before they are written into HTML attributes on an administrative page, as described in the CVE record with a CVSS 3.1 score of 6.1.

An unauthenticated remote attacker can supply a crafted URL that is later visited by an administrator; successful exploitation results in script execution within the administrator's browser session, yielding limited impacts to confidentiality and integrity while leaving availability unaffected.

The referenced WPScan report at https://wpscan.com/vulnerability/1772417a-1abb-4d97-9694-1254840defd1 documents the issue and identifies the fixed release. The associated EPSS score has remained flat at 0.1810 with no material increase after disclosure.
