CVE-2026-69854 is a critical severity flaw in Spring Cloud Azure, scored 9.0 by the record. Per the NVD record, it allows an unauthorized attacker to elevate privileges over a network. The record does not state a fixed build, so use the Microsoft advisory for the update that applies to your version and apply it.
What's affected
The NVD record lists Spring Cloud Azure as the affected product. The record describes the issue this way: Improper authentication in Spring Cloud Azure allows an unauthorized attacker to elevate privileges over a network.
The record gives a CVSS 3.1 base score of 9.0 (CRITICAL), published 2026-09-08, with the vector CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H. The vector reads as follows. Access is over the network, attack complexity is high, and privileges required are none. No user interaction is needed. Scope is changed, meaning impact can cross a security boundary. Confidentiality, integrity and availability impact are high, high and high.
The advisory is the authority on build numbers, and our automated fetch of the Microsoft page returned no advisory text, so this guide stops at what the NVD record states. Where Microsoft's advisory differs from this record on severity or versions, trust the advisory and note the difference in your own tracking.
How to check if you're exposed
List the Spring Cloud Azure artifacts on your dependency tree and read their versions.
mvn dependency:tree -Dincludes=com.azure.spring
Gradle projects can run the dependencies task and search for com.azure.spring. Compare the versions you find with the fixed release in the advisory, and check shared parent POMs and BOM imports, which often set the version without it appearing in your own file.
What to do now
- Read the Microsoft advisory and note the fixed Spring Cloud Azure release.
- Upgrade the dependency or BOM version and rebuild every service that uses it.
- Redeploy, then rescan the built artifacts to confirm the old version is gone.
- Review recent authentication logs on the affected services for anything unusual.
Why it matters
CWE-287 (improper authentication) describes a weakness where the system does not fully prove who is calling before trusting them.
Access control flaws in a hosted service or an identity library are hard to see from the outside. The fix may sit with the vendor, but the review of who has access and what the logs show stays with you.
The record's kev field is false, so the record does not list this CVE in CISA's Known Exploited Vulnerabilities catalog, and no fetched advisory said it was exploited. That is a snapshot, not a promise, so keep watching.
Safeguard's Gold page for this CVE tracks the record, and the free in-browser scan can check dependency manifests for related issues. Reachability analysis helps with libraries, though it does not apply to operating system patches.

Quick check
Does this CVE appear in the CISA Known Exploited Vulnerabilities list?
The record's kev field is false, so it is not listed in CISA's catalog as of the record we hold. That can change, so check the catalog if you are prioritizing.
Why is the score 9.0?
The vector shows no privileges and no interaction needed, but high attack complexity, and a changed scope. Scope change is what pushes the score into critical.
