CVE-2025-22235 is a high-severity improper input validation vulnerability in Spring Boot from Spring, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2.7.25, 3.1.16, 3.2.14 as the first without the flaw, so updating Spring Boot to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Spring Boot to 2.7.25 or 3.1.16 or 3.2.14 or 3.3.11, whichever matches your release line, or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

EndpointRequest.to() creates a matcher for null/** if the actuator endpoint, for which the EndpointRequest has been created, is disabled or not exposed. Your application may be affected by this if all the following conditions are met: * You use Spring Security * EndpointRequest.to() has been used in a Spring Security chain configuration * The endpoint which EndpointRequest references is disabled or not exposed via web * Your application handles requests to /null and this path needs protection You are not affected if any of the following is true: * You don't use Spring Security * You don't use EndpointRequest.to() * The endpoint which EndpointRequest.to() refers to is enabled and is exposed * Your application does not handle requests to /null or this path does not need protection

The underlying weakness: Improper Input Validation

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How developers prevent this class of flaw

  • Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build recognizers for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses.
  • Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
  • Understand all the potential areas where untrusted inputs can enter the product, including but not limited to: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
