How to fix

Copies a prompt for Claude Code, Cursor or Codex that asks it to check whether you run this product.
  1. Apply the vendor's update or mitigation from the references below. If there is none yet, limit exposure of the affected service until there is.
  2. If a vulnerable version was live, check your logs and rotate the secrets that server could read.

The advisory

A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw -- intended to require Administrator-level profiles.create permission -- to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy.

Check your whole app

Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
