| Doc Text: |
A flaw was found in Vault’s PKI engine. The ACME (Automated Certificate Management Environment) validation process did not properly restrict requests to local network targets when handling http-01 and tls-alpn-01 challenges. This vulnerability, known as Server-Side Request Forgery (SSRF), could allow a remote attacker to send crafted ACME validation challenges, potentially leading to the disclosure of sensitive information from internal network resources.
