Home page URL: Security reports for GutenBee – Gutenberg Blocks
Application: GutenBee – Gutenberg Blocks
Date: Sep 30, 2025

CVE, Research URL: CVE-2026-9227
Home page URL: Security reports for GutenBee – Gutenberg Blocks
Application: GutenBee – Gutenberg Blocks
Date: May 28, 2026
Research Description: The GutenBee – Gutenberg Blocks plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.20.1 via the gutenbee_file_and_ext_json function. This is due to a flawed strpos() substring check that only verifies whether the filename contains the string '.json' rather than confirming the filename ends with a .json extension, allowing double-extension filenames like shell.json.php to bypass validation. This makes it possible for authenticated attackers, with author-level access and above, to upload files that may be executable, which makes remote code execution possible.
Affected versions: max 2.20.2.
Status: vulnerable
