Published: 26 January 2023
Summary
CVE-2023-0448 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Matbao Wp Helper Premium. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 3.5% 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 WP Helper Lite WordPress plugin in versions prior to 4.3 is affected by a reflected cross-site scripting vulnerability (CWE-79). The root cause is that the plugin returns all supplied GET parameters in its HTTP responses without any sanitization or output encoding, allowing attacker-controlled content to be reflected directly into the page rendered by the browser.
An unauthenticated remote attacker can exploit the flaw by crafting a URL containing a malicious script in a GET parameter and inducing a victim to visit it. Successful exploitation results in script execution in the context of the vulnerable site, with impacts limited to confidentiality and integrity exposure for the affected user session.
The associated EPSS score has remained flat at 0.2767 with no material increase after disclosure.
