Vulnerability Title
LiteSpeed Cache < 4.4.4 - IP Check Bypass to Unauthenticated Stored XSS
Source: CVE Program / CVE List V5
Vulnerability Description
The LiteSpeed Cache WordPress plugin before 4.4.4 does not properly verify that requests are coming from QUIC.cloud servers, allowing attackers to make requests to certain endpoints by using a specific X-Forwarded-For header value. In addition, one of the endpoint could be used to set CSS code if a setting is enabled, which will then be output in some pages without being sanitised and escaped. Combining those two issues, an unauthenticated attacker could put Cross-Site Scripting payloads in pages visited by users.
