CVE-2026-5758

A flaw was found in the protocol-buffers-schema JavaScript library. This vulnerability, known as prototype pollution, allows an attacker to inject malicious properties into an object's core definition. This could enable an attacker to change how an application behaves, bypass security measures, o...
