Short explanation

Backdrop CMS Core 1.35.x before 1.35.2 and 1.34.x before 1.34.6 contains a token mishandling vulnerability. The flaw stems from insufficient access limits on available token types within the token browser, potentially leading to high confidentiality impact.

Why does it matter?

The lack of proper access controls allows attackers to interact with unrestricted token types that automatically insert dynamic data, potentially exposing sensitive information.

Show the technical text from the sources

Backdrop CMS Core 1.35.x before 1.35.2 and 1.34.x before 1.34.6 mishandles tokens. A token is a small placeholder string (like [node:title] or [user:name]) used to automatically insert dynamic data into text. A browser is provided for selecting tokens by type. The product doesn't sufficiently limit access to the types of tokens that are available in the token browser. The names of the individual tokens are adequately protected.
