WordPress Plugin Vulnerabilities
Time Sheets < 1.29.3 - Admin+ Stored XSS
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
Proof of Concept
1. Login as Admin. 2. Go to https://example.com/wp-admin/admin.php?page=time_sheets_settings 3. Insert the payload `'><script>alert(1)</script>` in the field `Email address to email when a project is over on hours:` 4. Click on save changes and XSS payload will be stored and triggered.
