CVE-2026-86444: CWE-79 Cross-Site Scripting (XSS) in LearnPress
The LearnPress WordPress plugin before 4.4.7 does not escape a user supplied value before using it in an HTML attribute on a public page, allowing unauthenticated attackers to execute arbitrary JavaScript in the browser of anyone who opens a crafted link, including a logged in administrator. Only sites running a classic, non-block are affected.
AI Analysis
Technical Summary
LearnPress versions from 4.2.6.4 up to but not including 4.4.7 contain a Cross-Site Scripting (CWE-79) vulnerability. The plugin fails to escape user input before inserting it into an HTML attribute on a public page, enabling unauthenticated attackers to inject and execute arbitrary JavaScript code in the context of any user who visits a crafted URL. This includes the possibility of impacting logged-in administrators. The issue is limited to sites using the classic editor rather than the block editor.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in the browser of any user who visits a maliciously crafted link. This can lead to session hijacking, privilege escalation, or other malicious actions within the context of the affected site. The vulnerability affects all users who open the crafted link, including administrators, potentially compromising site control.
Mitigation Recommendations
A fixed version of LearnPress is available at version 4.4.7. Users should upgrade to LearnPress 4.4.7 or later to remediate this vulnerability. Since the vulnerability affects only sites using the classic editor, switching to the block editor may reduce exposure, but upgrading is the recommended and definitive fix.
