• Severity: medium (CVSS 4.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

The Insert PHP Code Snippet plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the user's name when accessing the insert-php-code-snippet-manage page in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
