CVE-2025-22232: Spring Cloud Config Server may not use Vault token sent by clients using a X-CONFIG-TOKEN header when making requests to Vault.

Spring Cloud Config Server may not use Vault token sent by clients using a X-CONFIG-TOKEN header when making requests to Vault.

Spring Cloud Config Server may not use Vault token sent by clients using a X-CONFIG-TOKEN header when making requests to Vault. Your application may be affected by this if the following are true: * You have Spring Vault on the classpath of your Spring Cloud Config Server and * You are using the X-CONFIG-TOKEN header to send a Vault token to the Spring Cloud Config Server for the Config Server to use when making requests to Vault and * You are using the default Spring Vault SessionManager implementation LifecycleAwareSessionManager or a SessionManager implementation that persists the Vault token such as SimpleSessionManager. In this case the SessionManager persists the first token it retrieves and will continue to use that token even if client requests to the Spring Cloud Config Server include a X-CONFIG-TOKEN header with a different value. Affected Spring Products and Versions Spring Cloud Config: * 2.2.1.RELEASE - 4.2.1 Mitigation Users of affected versions should upgrade to the corresponding fixed version.

What it means for a small business

If your business uses Spring Cloud Config, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.32%, higher than 24% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
