- Description: The WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's su_meta shortcode combined with post meta data in all versions up to, and including, 5.13.3 due to insufficient input sanitization and output escaping on user supplied meta values.

- Name: WP Shortcodes Plugin — Shortcodes Ultimate <= 5.13.3 - Insecure Direct Object Reference to Information Disclosure
- Title: Insecure Direct Object Reference to Information Disclosure
- Type: Authorization Bypass Through User-Controlled Key
- CVE: CVE-2023-6226
- CVSS Score: 4.3 (Medium)
- Publicly Published: November 27, 2023
- Researcher: 4.3 (Medium)
- Description: The WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.13.3 via the su_meta shortcode due to missing validation on the user controlled keys 'key' and 'post_id'. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve arbitrary post meta values which may contain sensitive information when combined with another plugin.
The Shortcodes Ultimate plugin for WordPress has vulnerabilities in versions up to and including 5.13.3 that enable authenticated stored cross-site scripting and insecure direct object reference to information disclosure. These vulnerabilities have been patched in version 7.0.0.
The second vulnerability (CVE-2023-6226) is caused by missing access controls on the su_meta shortcode's key and post_id parameters. By manipulating these values, authenticated users can retrieve sensitive information from arbitrary posts. This could expose private data when combined with certain other plugins.
Together, these flaws enable a range of attacks from stored XSS to information exposure. All users are advised to update to version 7.0.0 or higher as soon as possible.
Advice for Users:
- Immediate Action: Update to the latest patched release, version 7.0.0, as soon as possible.
- Alternate Plugins: Consider using an alternate shortcodes plugin as a precaution until you can fully update.
- Stay Updated: Always keep your plugins updated to avoid vulnerabilities.
The quick response by the developers to address these stored XSS and information disclosure flaws shows the importance of rapid patching. Shortcodes Ultimate users should upgrade to version 7.0.0 or higher immediately to protect their sites.
