Improper Authentication in Spring Authorization Server

CVE-2024-22258GHSA-x637-x8p3-5p22

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.springframework.security:spring-security-oauth2-authorization-server 1.2.3, 1.1.6), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Spring Authorization Server versions 1.0.0 - 1.0.5, 1.1.0 - 1.1.5, 1.2.0 - 1.2.2 and older unsupported versions are susceptible to a PKCE Downgrade Attack for Confidential Clients.

# Patch Next advisory brief: CVE-2024-22258

Advisory: Improper Authentication in Spring Authorization Server
IDs: CVE-2024-22258, GHSA-x637-x8p3-5p22
Record: https://patchnext.com/advisories/cve-2024-22258 (revision 1, source checked 26 Oct 2026, 16:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.springframework.security:spring-security-oauth2-authorization-server 1.2.3, 1.1.6. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.security:spring-security-oauth2-authorization-server: affected < 1.1.6; >= 1.2.0, < 1.2.3; fixed in 1.2.3, 1.1.6

## Suggested inspection (read-only)
- Maven org.springframework.security:spring-security-oauth2-authorization-server: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.springframework.security:spring-security-oauth2-authorization-server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
