CVE-2025-55274Network attack vector

Authenticated data disclosure via permissive CORS policy

Published Mar 26, 2026 · Updated Mar 26, 2026

CORS misconfiguration in HCL Aftermarket DPC 1.0.0 allows remote authenticated users to disclose sensitive data via browser requests. The cross-origin policy permits untrusted web origins to read authenticated API responses, but HCL has not identified the affected endpoint. Exploitation requires low-privileged access and user interaction and exposes limited sensitive data; no data modification or service interruption is established.
