Oracle Secure Backup: Missing authentication allows unauthenticated takeover
Summary
Oracle Secure Backup versions 19.1.0.0.0 and 19.1.0.1.0 contain a flaw in the Backup and Restore component that is rated critical (CVSS 9.8). The CNA and Oracle describe it as reachable over the network via TCP without authentication, with the possibility of full takeover of the product. Oracle's text-form risk matrix also contains a statement that this vulnerability cannot be exploited in the context of this product, which conflicts with the main rating and has not yet been clarified.
Affected
- Oracle Secure Backup 19.1.0.0.0
- Oracle Secure Backup 19.1.0.1.0
Fixed in
Unknown. No fixed version or patch number was identified in the sources. Check the Oracle Critical Patch Update Advisory (October 2026) or My Oracle Support for patch availability.
Workaround
- No official workaround was found in the sources.
- Limit network access to the Secure Backup TCP service to required admin and backup hosts.
- Confirm with Oracle whether an official mitigation exists.
Exploitation
- No known exploitation in the wild was found at the time of research.
- No public proof of concept was found.
- One aggregator lists the CVE as not included in CISA KEV (status unverified against the catalogue).
- The CNA rates exploitation as automatable with total technical impact.
Our recommendation
- Check whether any system runs Secure Backup 19.1.0.0.0 or 19.1.0.1.0, for example through an asset inventory.
- If affected, confirm that the TCP service is not reachable from the internet or less-trusted network segments.
- Apply the Oracle patch as soon as it is available, using the fixed version from the Oracle advisory or My Oracle Support.
- Ask Oracle to clarify the note that the vulnerability cannot be exploited in the context of this product.
- Monitor the CISA KEV catalogue and Oracle's advisories for changes.
- Assess CVE-2026-109618 (PHP component, same versions) together with this CVE.
