• CVE-2019-3778: 16.60% estimated exploitation activity in the next 30 days; percentile 97.02 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Spring Security OAuth, versions 2.3 prior to 2.3.5, and 2.2 prior to 2.2.4, and 2.1 prior to 2.1.4, and 2.0 prior to 2.0.17, and older unsupported versions could be susceptible to an open redirector attack that can leak an authorization code. A malicious user or attacker can craft a request to the authorization endpoint using the authorization code grant type, and specify a manipulated redirection URI via the "redirecturi" parameter. This can cause the authorization server to redirect the resource owner user-agent to a URI under the control of the attacker with the leaked authorization code. This vulnerability exposes applications that meet all of the following requirements: Act in the role of an Authorization Server (e.g. @EnableAuthorizationServer) and uses the DefaultRedirectResolver in the AuthorizationEndpoint. This vulnerability does not expose applications that: Act in the role of an Authorization Server and uses a different RedirectResolver implementation other than…

# Patch Next advisory brief: CVE-2019-3778

Advisory: spring-security-oauth and spring-security-oauth2 Open Redirect vulnerability
IDs: CVE-2019-3778, GHSA-77rv-6vfw-x4gc
Record: https://patchnext.com/advisories/cve-2019-3778 (revision 1, source checked 26 Oct 2026, 16:11 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
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.oauth:spring-security-oauth 2.3.5.RELEASE, 2.2.4.RELEASE, 2.1.4.RELEASE, 2.0.17.RELEASE; org.springframework.security.oauth:spring-security-oauth2 2.3.5.RELEASE, 2.2.4.RELEASE, 2.1.4.RELEASE, 2.0.17.RELEASE. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.springframework.security.oauth:spring-security-oauth: affected < 2.0.17.RELEASE; >= 2.1.0.RELEASE, < 2.1.4.RELEASE; >= 2.2.0.RELEASE, < 2.2.4.RELEASE; >= 2.3.0.RELEASE, < 2.3.5.RELEASE; fixed in 2.3.5.RELEASE, 2.1.4.RELEASE, 2.2.4.RELEASE, 2.0.17.RELEASE
- Maven org.springframework.security.oauth:spring-security-oauth2: affected < 2.0.17.RELEASE; >= 2.1.0.RELEASE, < 2.1.4.RELEASE; >= 2.2.0.RELEASE, < 2.2.4.RELEASE; >= 2.3.0.RELEASE, < 2.3.5.RELEASE; fixed in 2.3.5.RELEASE, 2.1.4.RELEASE, 2.2.4.RELEASE, 2.0.17.RELEASE

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