CVE-2025-48977Network attack vector

Authenticated arbitrary file read via unnormalized log path

Published May 28, 2026 · Updated May 28, 2026

Path traversal in Apache Ignite 2.0.0 through 2.17.0 allows remote authenticated users to read server files via the REST API. GridLogCommandHandler tests the raw cmd=log path as a string prefix instead of normalizing and canonicalizing it before FileReader opens it. The ignite-rest-http module must be enabled and reachable; valid REST access exposes files readable by the server process without reported modification.
