CVE ID : CVE-2025-9849

Published : Sept. 6, 2025, 2:15 a.m. | 24 minutes ago

Description : The Html Social share buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘zm_sh_btn’ shortcode in all versions up to, and including, 2.1.16 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.

Severity: 5.3 | MEDIUM
