CVE-2026-3375

The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the /wp-json/litespeed/v1/notify_ccss and /wp-json/litespeed/v1/notify_ucss REST API endpoints in all versions up to, and including, 7.7. These endpoints accept CSS content from QUIC.cloud callback notifications and store it to disk without sanitization. The stored content is later rendered inline frontend page loads without output escaping. The access control protecting these endpoints is IP-based validation that can potentially be bypassed when the WordPress site is deployed behind a reverse proxy, load balancer, or CDN with certain configurations. This makes it possible for unauthenticated attackers, under certain conditions, to inject arbitrary JavaScript into CCSS/UCSS content.

CVE-2024-50550

The LiteSpeed Cache plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 6.5.1.

This makes it possible for unauthenticated attackers to simulate roles such as administrators which provides elevated access to the site. Please note there are a lot of pre-requisites for this to be exploitable.

CVE-2024-9169

The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin debug settings in all versions up to, and including, 6.4.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

CVE-2024-44000

The LiteSpeed Cache plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 6.4.1 through the debug.log file that is publicly exposed. This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed log file. The log file may contain user cookies making it possible for an attacker to log in with any session that is actively valid and exposed in the log file. Note: the debug feature must be enabled for this to be a concern and this feature is disabled by default.

CVE-2024-28000

The LiteSpeed Cache plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 6.3.0.1. This is due to the plugin not properly restricting the role simulation functionality allowing a user to set their current ID to that of an administrator, if they have access to a valid hash which can be found in the debug logs or brute forced. This makes it possible for unauthenticated attackers to spoof their user ID to that of an administrator, and then create a new user account with the administrator role utilizing the /wp-json/wp/v2/users REST API endpoint. In some environments, the crawler may be disabled making this a non-exploitable issue in those instances.

CVE-2024-3246

The LiteSpeed Cache plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.2.0.1. This is due to missing or incorrect nonce validation. This makes it possible for unauthenticated attackers to update the token setting and inject malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2021-24964

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.
