What is the specific vulnerability discovered in the LiteSpeed Cache plugin?

The vulnerability in the LiteSpeed Cache plugin is an unauthenticated privilege escalation flaw. This vulnerability allows attackers to escalate their privileges to that of an administrator by exploiting the plugin's role simulation functionality. If an attacker gains access to a valid hash, they can use it to spoof their user ID and create a new user account with administrative privileges through the REST API, posing a severe risk to the website.

Question 3

Who is at risk from this vulnerability?

Accepted Answer

Who is at risk from this vulnerability?

Any website using the LiteSpeed Cache plugin in versions up to and including 6.3.0.1 is at risk. The vulnerability is particularly dangerous because it can be exploited by unauthenticated attackers, meaning they don’t need existing access to the site to execute the attack. Websites that rely heavily on this plugin and have not yet updated to version 6.4 are especially vulnerable to potential attacks.
