hubspotdev vulnerabilities and threats

The HubSpot All-In-One Marketing – Forms, Popups, Live Chat plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.3.62 via the wp_localize_script() / window.leadinConfig JavaScript object. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the site's plaintext HubSpot OAuth refresh token exposed via the window.leadinConfig JavaScript object, which can then be used to access or modify data in the connected HubSpot tenant. Although the refresh token is stored at rest with AES-256-CTR encryption, decryption occurs server-side before the plaintext value is passed to wp_localize_script(), rendering the at-rest encryption ineffective against this exposure path.

CVE-2025-11762 is a medium severity vulnerability in the HubSpot All-In-One Marketing - Forms, Popups, Live Chat WordPress plugin. It allows authenticated users with Contributor-level access or higher to access sensitive information by extracting a list of all installed plugins and their versions. This vulnerability exists in all versions up to and including 11.3.32 and is due to missing authorization checks in a specific PHP file. No official patch or remediation guidance is currently available from the vendor. The vulnerability does not affect cloud services and no known exploits are reported in the wild.

The HubSpot – CRM, Email Marketing, Live Chat, Forms & Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'url' attribute of the HubSpot Meeting Widget in all versions up to, and including, 11.1.22 due to insufficient input sanitization and output escaping. 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.
