What is CVE-2026-41712?

CVE-2026-41712 is an information disclosure flaw in Spring AI. The product returns sensitive data to a caller who should not have access, including credentials, session tokens, or configuration. Disclosure often feeds a follow-up attack chain. Vendor description: Spring AI's chat memory component contained a problematic default that, when not explicitly overridden, could result in unintended data exposure between users.

Why this CVE matters

Information disclosure flaws are dangerous because they make the next attack easier. Sensitive configuration, session material, or credentials leaked from one endpoint frequently power the follow-on attack that actually takes over the system.

For deployments of Spring AI that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.

Am I affected?

You are affected if your installation matches any of these version ranges:

Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.

On VMware ESXi, run vmware -vl to read the build number. On vCenter, the version is shown on the login banner and in the admin UI under the Help menu.

How to fix CVE-2026-41712

  1. Read the vendor advisory in full: https://spring.io/security/cve-2026-41712
  2. Upgrade Spring AI to the patched build listed in the vendor advisory.
  3. Back up the configuration (and database, where applicable) before upgrading.
  4. Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
  5. Restart the affected service so the patched binary loads, then verify the new version (see verification section).

Update the maven / gradle dependency


# CVE-2026-41712 affects Spring AI 1.0.0 < 1.0.7. Fixed in 1.0.7.
# Vendor advisory: https://spring.io/security/cve-2026-41712

# Maven: bump the dependency in pom.xml then re-resolve.
mvn versions:use-dep-version -Dincludes=spring-ai -DdepVersion=1.0.7 -DforceVersion=true
mvn clean install

# Gradle: bump in build.gradle then refresh.
./gradlew --refresh-dependencies build

# Restart the affected JVM service so the patched JAR loads.
sudo systemctl restart <service-name>

# Verify the runtime is on the patched build.
java -version


# Vendor advisory: https://spring.io/security/cve-2026-41712
# Restart the equivalent Windows service after upgrading the JAR.
Restart-Service -Name "<service-name>"
Get-Service -Name "<service-name>"

Verify the fix landed


# CVE-2026-41712 verification checklist.

# 1. Confirm the running version matches 1.0.7 (replace the version probe with
#    the platform-specific command shown above).

# 2. Re-scan the host with your vulnerability scanner (Nessus, Qualys, Tenable,
#    OpenVAS, Wazuh). The scanner must no longer flag CVE-2026-41712.

# 3. Inspect recent service and kernel logs for crash-loops or rollback events.
journalctl -u <service-name> --since "10 minutes ago"
dmesg --since "10 minutes ago"

# 4. Cross-check the running build against the vendor advisory:
#    https://spring.io/security/cve-2026-41712

If you cannot patch immediately

No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.

How to verify the fix worked

If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for unusually long URI paths containing traversal sequences, unexpectedly large responses from the affected endpoint, and outbound requests from the application to internal addresses or cloud-metadata endpoints. Treat any sensitive file the bug could disclose as exposed.

Frequently asked questions

Is CVE-2026-41712 being exploited in the wild?

Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.

Will a WAF or IDS rule fully mitigate CVE-2026-41712?

No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.

How long should I plan for the upgrade?

Typical vendor-documented upgrade windows for Spring AI run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
