CVE-2026-126312

OpenBao before 2.6.5 and 2.7.2 ACL Bypass via Non-Canonical Plugin Paths

OpenBao before 2.6.5 and 2.7.x before 2.7.2, and the openbao-plugins LDAP and RADIUS auth plugins before 0.2.0, contain an ACL bypass in the AppRole, Cert, LDAP, and RADIUS auth methods caused by implicit path canonicalization. Authenticated attackers can request non-canonical paths for AppRole Role IDs, Cert CRLs, LDAP groups and users, or RADIUS users to evade ACL deny rules.

CVE-2026-126323

Vvveb through 1.0.8.6 CSRF via GET Admin State-Changing Actions

Vvveb through 1.0.8.6 contains a cross-site request forgery vulnerability that allows attackers to perform admin state-changing actions because checkCsrf() in admin/controller/base.php only validates tokens for POST requests. Attackers can lure a logged-in admin into loading a forged cross-site GET request to delete admin/user accounts, sites, orders, and menus or change comment status.
