Oracle SOA Suite: Missing authentication in Adapters component
Summary
Oracle SOA Suite, part of Oracle Fusion Middleware, contains a flaw in its Adapters component. An unauthenticated attacker with network access via HTTP can create, delete or modify data accessible to SOA Suite and can cause a hang or repeatable crash (denial of service). NVD rates it CVSS 9.1 (critical) and lists CWE-306 and CWE-284. The impact depends on the SOA Suite endpoints being reachable from the network.
Affected
- Oracle SOA Suite 12.2.1.4.0
- Oracle SOA Suite 14.1.2.0.0
Fixed in
Unknown. Oracle's October 2026 Critical Patch Update (CPU) advisory is the reference, but no fixed version or patch number has been verified.
Workaround
- No vendor-confirmed workaround known.
- Generic option if patching is not possible: block external HTTP access to SOA Suite Adapters endpoints and allow only trusted internal networks. Effect on this CVE is unverified.
Exploitation
- No known exploitation in the wild and not listed in the CISA KEV catalog as of 21 October 2026.
- No public proof-of-concept known; these reports may be outdated.
- EPSS below 1% (OpenCVE).
- CISA SSVC: automatable yes, exploitation none.
Our recommendation
- Check whether any SOA Suite endpoint is reachable from the internet or untrusted networks and treat exposed systems as urgent.
- Obtain the fixed versions from Oracle's October 2026 CPU advisory and apply the complete SOA Suite patch set, not only this CVE.
- Until patched, restrict HTTP access to Adapters endpoints to trusted internal networks.
- Monitor SOA Suite logs for unexpected requests, data changes and service crashes.
- Note that scoring differs between sources (NVD 9.1; VulDB 6.5) and that the NVD status may still change.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
