ETK-2026-3778Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
Bindery deployments using tenancy enforcement are affected when user-role accounts exist. A user may be able to view book information belonging to other accounts and, in some shared-author cases, alter properties of other accounts' books. Deployments without tenancy enforcement do not use account boundaries for these libraries.
mitigation
Upgrade Bindery to version 1.46.3 or later. Until upgraded, assign untrusted accounts the requester role rather than the user role.
fixed in 1.46.3
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
