What is CVE-2026-59094?

The Pathway Document Store is susceptible to a denial of service attack due to its handling of caller-supplied glob patterns. From the unauthenticated HTTP endpoints, an attacker can submit malicious patterns that lead to high CPU consumption, as the application evaluates these patterns without sufficient restrictions. This results in prolonged processing times per request, allowing attackers to effectively disrupt service through a series of crafted requests.
