A critical security flaw in the popular WordPress plugin, LiteSpeed Cache, is being actively exploited by hackers to take complete control of vulnerable websites. This alarming discovery, reported by WPScan, reveals that attackers are using the vulnerability (CVE-2023-40000) to create rogue admin accounts, granting them unrestricted access and the ability to manipulate websites at will.
The vulnerability, a stored cross-site scripting (XSS) flaw, was disclosed in February 2024 and patched in October 2023. However, with over 5 million active installations of LiteSpeed Cache, a significant number of websites remain at risk as they haven’t updated to the latest secure version.
