CVE-2025-5253Network attack vector

Authenticated HTTP denial of service via resource exhaustion

Published Jul 25, 2025 · Updated Jun 5, 2026

Resource exhaustion in Kron Technologies Kron PAM before 3.7 allows remote authenticated users to interrupt HTTP service. The CNA identifies unbounded resource allocation during HTTP handling but does not disclose the endpoint, request field, or allocation operation. Low-privileged authenticated network access is required, and the reported consequence is loss of availability rather than data disclosure or modification.
