- Severity: CVSS 6.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

## Affected

- ider IDer Login for WordPress: through 2.1

## Description

The IDer Login for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ider_login_button' shortcode in all versions up to, and including, 2.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This affects version 2.1, but was also patched in version 2.1 - a new version was not released with the patch.
