description

Backdrop CMS Core 1.35.x before 1.35.2 and 1.34.x before 1.34.6 insufficiently restricts which token types appear in the token browser. An attacker may access token types that should not be available through that interface; the advisory does not establish a more specific precondition.

mitigation

Upgrade Backdrop CMS Core to 1.35.2 or later on the 1.35 branch, or to 1.34.6 or later on the 1.34 branch. Restrict access to token-browser functionality until the update is applied.

fixed in 1.35.2, 1.34.6
