- Oracle BI Publisher 26.01.0.0.0 (one Oracle advisory lists this as 26.1.0.0.0; confirm the exact build you run)
Fixed in

- No public proof of concept is known.
- The SSVC data in the CVE record lists exploitation as none and automatable as no.
- The CVE is not listed in CISA KEV.
Our recommendation
- Check whether BI Publisher is installed and which version runs.
- Check whether the BI Publisher web interface is reachable from the internet or untrusted networks, and treat an exposed instance as urgent.
- Apply the October 2026 Oracle CPU with the fixed build from Oracle's advisory. Do not patch to a guessed version.
- Until patched, remove direct internet exposure, restrict access to internal or VPN users, and warn users about links from unexpected sources.
- Review web server logs for unusual requests to the BI Publisher interface.
- Re-check the NVD entry and Oracle advisory regularly, as the record was still Awaiting Analysis.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
