Fixed in
Unknown. Check Oracle's October 2026 Critical Patch Update advisory for the fixed versions for Solaris 11.3 and 11.4.
Workaround
No vendor workaround known. Interim measures until patching:
- Restrict access to the Solaris HTTP service to management networks.
- Remove unused accounts and enforce strong passwords on low-privilege accounts.
- Review HTTP logs for unusual activity.
Exploitation
- Oracle does not report exploitation in the wild.
- Not listed in the CISA KEV catalogue as of 21 Oct 2026.
- No public proof of concept found.
- CISA SSVC: not automatable.
Our recommendation
- Identify all Solaris 11.3 and 11.4 hosts in your asset inventory.
- Apply the October 2026 Oracle CPU as soon as possible.
- Treat hosts reachable from the internet or shared with untrusted users as high priority.
- On Solaris 11.4 hosts, also check CVE-2026-101537 (CVSS 9.8, same component).
