CVE-2023-6806: Starbox <= 3.4.8 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Job Settings

The Starbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Job Settings user profile fields in all versions up to, and including, 3.4.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-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

CVE-2023-6806 is a stored cross-site scripting flaw in the Starbox WordPress plugin through version 3.4.8. A logged-in user with Subscriber-level access or higher could store script content in Job Settings profile fields, causing it to run when another user views the affected page.

Executive priority

Treat this as a moderate web application risk. Prioritize internet-facing WordPress sites with open registration or many low-privilege users. It is less urgent than unauthenticated code execution, but stored XSS can affect administrators and site visitors.

Technical view

The issue is CWE-79 caused by insufficient input sanitization and output escaping in Starbox Job Settings user profile fields. CVSS is 6.4, network exploitable, low complexity, low privileges required, changed scope, with limited confidentiality and integrity impact and no availability impact.

Likely exposure

Exposure is likely limited to WordPress sites using Starbox – the Author Box for Humans version 3.4.8 or earlier, especially where untrusted users can create or hold Subscriber-level accounts or higher.

Exploitation context

The source bundle does not show active exploitation, and KEV is false. Exploitation requires authenticated access, but no user interaction is required after injection beyond someone visiting a page that renders the stored content.

Researcher notes

The provided affected metadata is inconsistent, listing version "0" with defaultStatus "unaffected", while the CVE description states all versions up to and including 3.4.8 are vulnerable. Base conclusions on the narrative and cited Wordfence and WordPress Trac references.

Mitigation direction

  • Update Starbox to a version newer than 3.4.8 if available.
  • Check Wordfence and plugin vendor guidance for confirmed fixed versions.
  • Restrict untrusted Subscriber-level account creation until remediated.
  • Disable the plugin if no safe update is available.
  • Review existing user profile Job Settings content for suspicious scripts.

Validation and detection

  • Inventory WordPress sites for the Starbox plugin and installed version.
  • Flag any Starbox installation at version 3.4.8 or earlier.
  • Confirm whether public or untrusted users can authenticate as Subscriber or higher.
  • Review rendered author/profile pages for unexpected script execution indicators.
  • Verify updated plugin output escapes Job Settings fields in staging.
