Pcp: pcp pmproxy: unauthenticated access to /store endpoint allows bypassing pmcd access rules

An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.
