CVE-2024-13679: Widget BUY.BOX <= 3.1.5 - Authenticated (Contributor+) Stored Cross-Site Scripting

The Widget BUY.BOX plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'buybox-widget' shortcode in all versions up to, and including, 3.1.5 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.

Security readout for executives and security teams

Plain-English summary

A WordPress site using Widget BUY.BOX up to version 3.1.5 can let a logged-in Contributor or higher store malicious script through the plugin shortcode. The script runs when someone views the affected page. This is a business risk for sites with multiple authors, contractors, or compromised editor accounts.

Executive priority

Treat as a moderate-priority web publishing risk. Prioritize sites with public traffic, many content users, third-party contributors, or elevated account compromise concerns. Do not delay basic access review while waiting for fuller vendor remediation details.

Technical view

CVE-2024-13679 is stored cross-site scripting in the Widget BUY.BOX WordPress plugin buybox-widget shortcode. Sources cite insufficient sanitization and output escaping of shortcode attributes. The issue requires authenticated Contributor-level access or above and has CVSS 3.1 score 6.4, with low confidentiality and integrity impact and changed scope.

Likely exposure

Exposure is likely limited to WordPress installations running Widget BUY.BOX versions up to and including 3.1.5, especially where Contributor-level accounts exist. The source bundle does not identify affected hosting providers, themes, or other plugins.

Exploitation context

The bundle does not show CISA KEV listing or other cited evidence of active exploitation. The vulnerability is still meaningful because any Contributor-level account, including a compromised one, may persist script in content that later executes for visitors or administrators.

Researcher notes

Evidence supports authenticated stored XSS via shortcode attributes and CWE-79. The bundle does not name a patched version, exploit activity, or detailed code-diff remediation. The affected metadata also includes an odd version value, so rely on the narrative version range up to 3.1.5.

Mitigation direction

  • Inventory WordPress sites for Widget BUY.BOX and record installed versions.
  • Check vendor or WordPress plugin guidance for a fixed release before upgrading.
  • Disable or remove the plugin where it is not business-critical.
  • Restrict Contributor-level access to trusted users only.
  • Review existing content using the buybox-widget shortcode for suspicious attributes.

Validation and detection

  • Confirm whether Widget BUY.BOX is installed and whether the version is 3.1.5 or older.
  • List WordPress accounts with Contributor, Author, Editor, or Administrator roles.
  • Audit posts and pages containing the buybox-widget shortcode.
  • Verify shortcode output escaping in staging using benign test strings.
  • Confirm any remediation against vendor guidance once available.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
