Publication date: 2026-08-05

Last updated on: 2026-08-05

Assigner: Wordfence

Description
The Simple Yearly Archive plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `posttype` attribute of the `SimpleYearlyArchive` shortcode in all versions up to, and including, 2.2.4 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.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Simple Yearly Archive WordPress plugin up to version 2.2.4. It allows authenticated attackers with Contributor-level access or higher to inject malicious scripts via the posttype attribute in the SimpleYearlyArchive shortcode due to insufficient input sanitization and output escaping.

Detection Guidance

Check WordPress sites for the Simple Yearly Archive plugin versions up to 2.2.4. Inspect shortcode usage for posttype attributes with unsanitized input. Review server logs for unusual script injections in page content.

Impact Analysis
  • Attackers could inject scripts that execute when users access infected pages, potentially stealing cookies, session tokens, or other sensitive data.
  • Malicious scripts might redirect users to phishing sites or perform actions on their behalf without consent.
  • The vulnerability requires Contributor-level access or higher, limiting the potential impact to authenticated users with those privileges.
Compliance Impact

This vulnerability could lead to unauthorized data access or modification, potentially violating GDPR (data protection) and HIPAA (health data privacy) requirements for safeguarding user information. Exploitation may result in non-compliance penalties if sensitive data is compromised.

Mitigation Strategies

Update the Simple Yearly Archive plugin to version 2.2.5 or later. Remove or restrict Contributor-level access to untrusted users. Scan WordPress installations for injected scripts in posts or pages.
