The LiteSpeed Cache WordPress plugin prior to 4.4.4 does not properly verify that requests are coming from QUIC.cloud servers, allowing malicious users 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.
