CVE-2026-128037
What it is
In gittuf 0.10.0 through 0.15.0, when a minimum threshold global rule and a policy rule protect the same namespace, verification gives the global rule's check over all trusted users in the policy precedence over the policy rule's own authorized users. A user listed in the policy file but not authorized by the policy rule, or fewer users than the rule's threshold, can make changes to the protected namespace that pass verification.
