CVE-2025-62238
📋 TL;DR
This stored XSS vulnerability allows authenticated attackers to inject malicious scripts into the Account Name field on the Membership page in Liferay Portal/DXP. When other users view the affected page, the script executes in their browser context. All users of affected Liferay versions with access to account settings are potentially impacted.
💻 Affected Systems
- Liferay Portal
- Liferay DXP
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as other users, redirect to malicious sites, or deploy malware through the compromised portal.
Likely Case
Session hijacking, credential theft, defacement of user profiles, or limited data exfiltration from users who view the malicious payload.
If Mitigated
Script execution blocked by CSP headers or input sanitization, limiting impact to minor UI disruption.
🎯 Exploit Status
Requires authenticated access and knowledge of XSS payloads; stored nature makes exploitation persistent.
