LiteSpeed Cache, CVE-2021-24964

CVE, Research URL: CVE-2021-24964
Home page URL: Security reports for LiteSpeed Cache
Application: LiteSpeed Cache
Published on: Jan 03, 2022
Research 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.
Affected versions: Min -, max 4.4.4.
Status: vulnerable
