Published: 13 June 2022
Summary
CVE-2022-1724 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Simple-Membership-Plugin Simple Membership. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 9.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The vulnerability is a reflected cross-site scripting flaw (CWE-79) affecting the Simple Membership WordPress plugin prior to version 4.1.1. It stems from insufficient sanitization and escaping of user-supplied parameters that are echoed back in AJAX responses, as reflected in its CVSS 6.1 rating (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
An unauthenticated remote attacker can exploit the issue by crafting a malicious link or request that, when visited by a logged-in or unauthenticated user, causes arbitrary script to execute in the context of the affected site. Successful exploitation can lead to limited theft of cookies or other client-side actions without requiring authentication.
The EPSS score remains low, with a current value of 0.0522 and a peak of only 0.0589, indicating no material post-disclosure rise in exploitation interest.
