CVE-2026-46830Network attack vector

Unauthenticated data disclosure via undisclosed Mongoapi flaw

Published May 28, 2026 · Updated May 28, 2026

Information disclosure in Oracle REST Data Services 24.2.0 through 26.1.0 allows remote attackers to read a subset of data via HTTPS. Oracle has not disclosed which Mongoapi handler or request field performs the unauthorized read, so the faulty operation is not public. The MongoDB API must be enabled on a network-reachable standalone instance; the reported consequence is limited to confidentiality.
