CVE-2022-26884Network attack vector

Arbitrary file read via log-server path traversal

Published Oct 28, 2022 · Updated May 7, 2025

Path traversal in the log server in Apache DolphinScheduler before 2.0.6 allows remote attackers to read arbitrary files via crafted paths. LoggerRequestProcessor passed command-supplied paths directly to whole-file, partial-file, and byte-read routines without validating that they remained within the log directory. The log server enforces no authentication; exploitation requires network reachability to that service and exposes only files readable by its process account.
