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

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.boot:spring-boot, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    A fix is available for CVE-2025-22235; check the affected-versions list above or the advisory for the patched release of org.springframework.boot:spring-boot, then make sure no transitive dependency still pins the vulnerable range.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
