CVE-2021-24308 is a stored Cross-Site Scripting (XSS) vulnerability affecting the LifterLMS plugin for WordPress versions prior to 4.21.1. Specifically, the 'State' field in the Edit profile page is not properly sanitized, allowing malicious script injection when displayed in the About section of a user's profile. This medium-severity vulnerability (CVSS 5.4) could enable low-privilege users, such as students, to elevate their privileges if an administrator views their compromised profile. While not actively exploited in the wild and lacking significant community discussion or media coverage, exploit code is publicly available via ExploitDB (EDB-49912).
