CVE-2026-83419Network attack vector

Authenticated data disclosure and modification

Published Sep 15, 2026 · Updated Sep 15, 2026

Access control failure in Oracle SEPP 25.2.201 and 26.1.200 allows remote authenticated users to read and alter data via HTTP. Oracle identifies the affected component only as SEPP and does not disclose the request handler, authorization check, or input path that wrongly permits the access. Low-privileged HTTP access is required; successful attacks expose a subset of accessible data and permit some records to be inserted, updated, or deleted.
