CVE-2025-59043
Description
A critical Denial of Service vulnerability has been identified in the OpenBao secrets management system. This flaw allows an unauthenticated attacker to send a specially crafted data request, a JSON payload, that consumes a disproportionate amount of memory when processed, functioning like a memory-based "zip bomb." This exploit bypasses standard security configurations intended to limit request sizes and prevent service disruptions. Successfully exploiting this vulnerability leads to an out-of-memory crash of the OpenBao server, resulting in a complete Denial of Service for the secrets management system.
Statement

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
