CVE-2026-31817Public exploitNetwork attack vector

Authenticated arbitrary file write via tracking ID traversal

Published Mar 10, 2026 · Updated Mar 10, 2026

Path traversal in OliveTin before 3000.11.2 allows remote authenticated users to write files outside the configured log directory. With saveLogs enabled, stepSaveLog places StartAction's unvalidated UniqueTrackingId into .yaml and .log paths, so traversal segments escape that directory. StartAction access and OliveTin process write permission are required; resulting files can overwrite application or system data.
