## Overview

## Impact

When a policy operator has written `capabilities = ["deny"]` on a path with a trailing wildcard but allowed a broader list operation (e.g., a `deny` on `secrets/metadata/restricted/*` but allowed `list` on `secrets/metadata/*`), OpenBao would incorrectly allow the operation. This did not impact other operation types.

## Patches

This has been patched in OpenBao v2.6.0.

## Affected packages

- `github.com/openbao/openbao < 0.0.0-20260713133043-f58d848c139e`
- `github.com/openbao/openbao >= 0.1.0, <= 1.1.5`

## Remediation

Upgrade to a patched release:

- `github.com/openbao/openbao 0.0.0-20260713133043-f58d848c139e`
