CVE-2023-6958: WP Recipe Maker <= 9.1.0 - Authenticated(Contributor+) Stored Cross-Site Scripting via Shortcode

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 9.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions 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 logged-in WordPress user with Contributor or higher rights could store script code through WP Recipe Maker shortcodes. The script would run when visitors open the affected page. This can expose user data or alter page content, but it requires an account with publishing-related access and affects plugin versions through 9.1.0.

Executive priority

Treat this as a moderate website integrity risk. Prioritize sites with many content contributors, public registration, agency access, or sensitive logged-in users. Patch during the next maintenance window, faster if Contributor accounts are broadly distributed.

Technical view

CWE-79 stored XSS in WP Recipe Maker <= 9.1.0 stems from insufficient sanitization and output escaping of user-supplied shortcode attributes. The CVSS 3.1 score is 6.4 with low attack complexity, low privileges required, changed scope, and limited confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites using WP Recipe Maker versions up to and including 9.1.0 where Contributor-level or higher accounts can create or edit content containing plugin shortcodes.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation evidence. Abuse requires an authenticated Contributor-or-higher account and a page or post where malicious shortcode attributes can be stored and later rendered to other users.

Researcher notes

Focus validation on shortcode rendering paths and stored content authored by Contributor-level users. The available evidence identifies the vulnerable class and a WordPress Trac changeset, but does not provide exploit-in-the-wild confirmation or broader affected-product claims.

Mitigation direction

  • Update WP Recipe Maker to a vendor-supported version newer than 9.1.0.
  • Review vendor and WordPress plugin guidance for the fixed release details.
  • Restrict Contributor and higher roles to trusted users only.
  • Review recent recipe content and shortcode usage from lower-privileged authors.
  • Remove unexpected scripts, event handlers, or suspicious attributes from affected content.

Validation and detection

  • Inventory WordPress sites using WP Recipe Maker and record installed versions.
  • Confirm no production site runs WP Recipe Maker 9.1.0 or earlier.
  • Review pages and posts containing WP Recipe Maker shortcodes.
  • Check author permissions for accounts able to create or edit recipe content.
  • Verify the plugin includes the shortcode escaping changes referenced by WordPress Trac.

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.
