- 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

- morettolss Google+ Link Name: through 1.0

## Description

The Google+ Link Name plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gplusnamelink' shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user supplied attributes ('id' and 'name') in the gplusnamelink_generate() function, which are concatenated directly into the rendered HTML without calling esc_attr() or esc_html(). 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.
