CVE-2025-9128Network attack vector

Contributor-level stored script execution via unescaped shortcode ID

Published Sep 11, 2025 · Updated Apr 8, 2026

Stored XSS in eID Easy 4.9.3 and earlier allows remote authenticated users to inject scripts through the contract shortcode's id attribute. The display_contract_to_sign handler places the shortcode value into an iframe URL that is returned as HTML without adequate input sanitization and output escaping. Contributor-level access is required, and the persisted script runs in the browser of every user who opens the affected page.
