CVE-2026-115361 Details
Description
OpenBao before 2.6.3 contains an ACL bypass vulnerability that silently drops explicit deny rules based on forbidden identity metadata templates within wildcard grants. Attackers whose identity metadata contains wildcard or path segments can access paths that should be denied within the broader wildcard-granted scope.
A vulnerability in OpenBao versions prior to 2.6.3 allows for an Access Control List (ACL) bypass. This issue arises because the system silently ignores explicit deny rules that are based on forbidden identity metadata templates when these templates are included in wildcard grants. As a result, attackers whose identity metadata features wildcard or path segments can access paths that should be denied, within the wider scope of the wildcard grant.
Users can upgrade to OpenBao versions 2.6.3 or 2.7.0 to address this vulnerability.
