Input validation vulnerability in Blog Filter – Advanced Post Filtering with Categories Or Tags, Post Portfolio Gallery, Blog Design Template, Post Layout 1.5.3

  • Severity: medium-risk
  • Status: Fixed
  • Publication: October 3, 2023

The Blog Filter plugin for WordPress is not secure in versions up to and including 1.5.3. This plugin is vulnerable to a type of attack called Stored Cross-Site Scripting. This type of attack is possible when authenticated attackers with contributor-level (or higher) permissions can inject malicious web scripts into pages, which will then execute when a user accesses the page. This can be prevented if there is proper input sanitization and output escaping of user-supplied attributes.
