CVE-2024-7313
Published: 26 August 2024
Summary
CVE-2024-7313 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Getshieldsecurity Shield Security. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 2.1% 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 Shield Security WordPress plugin before version 20.0.6 contains a reflected cross-site scripting vulnerability (CWE-79) with a CVSS 3.1 score of 6.1. The root cause is insufficient sanitization and escaping of an unspecified parameter that is reflected back into page output, allowing script execution in the context of the affected site.
An unauthenticated attacker can supply a crafted URL containing malicious JavaScript; when a high-privilege user such as an administrator follows the link, the script executes in the victim's browser with the site's origin, enabling limited confidentiality and integrity impacts under changed scope.
The referenced WPScan advisory identifies the issue in versions prior to 20.0.6 and indicates that updating to 20.0.6 or later resolves the flaw. The associated EPSS score rose from lower values to a peak of 0.7015 before receding to the current 0.4951, indicating post-disclosure exploitation interest that later declined.
