Spring security advisory (AV26-592)
Analysis Summary
# Vulnerability: Spring Framework Product Suite Multiple Vulnerabilities
## CVE Details
- **CVE ID:** CVE IDs were not explicitly detailed in the summary report AV26-592; however, this advisory refers to a collection of vulnerabilities addressed between June 10–11, 2026.
- **CVSS Score:** Not specified in the source (refer to Spring.io for individual scores).
- **CWE:** Varies by specific component (likely including Injection, Broken Access Control, or Denial of Service).
## Affected Systems
- **Products:** Spring Cloud Sleuth, Spring Statemachine, Spring Cloud Gateway, Spring Integration, Spring for GraphQL.
- **Versions:**
- **Spring Cloud Sleuth:** 3.1.0 to 3.1.13.
- **Other Products:** "Multiple versions" (Specific version ranges are detailed in individual underlying advisories).
- **Configurations:** Default configurations of the mentioned microservices and integration frameworks.
## Vulnerability Description
While the Canadian Centre for Cyber Security (CCCS) bulletin functions as a high-level notification, these vulnerabilities typically involve flaws in how Spring components handle data parsing, state transitions, or gateway routing. Specifically for **Spring Cloud Sleuth**, the vulnerability likely pertains to information disclosure or trace manipulation within the logging and instrumentation logic.
## Exploitation
- **Status:** Not reported as exploited in the wild at the time of the advisory.
- **Complexity:** Generally Low to Medium (depending on the specific component).
- **Attack Vector:** Network (Most Spring Framework vulnerabilities are remotely exploitable via HTTP/API requests).
## Impact
- **Confidentiality:** High (Potential for information disclosure in Sleuth/GraphQL).
- **Integrity:** High (Potential for manipulation of state in Statemachine or routing in Gateway).
- **Availability:** Variable (Potential for DoS depending on the specific component flaw).
## Remediation
### Patches
Users are advised to upgrade to the following versions or newer:
- **Spring Cloud Sleuth:** Upgrade to a version outside the 3.1.0-3.1.13 range (Note: Sleuth has been succeeded by Micrometer Tracing; migration may be required).
- **Other Components:** Refer to the official [Spring Security page](https://spring[.]io/security) for the latest patched releases for Statemachine, Gateway, Integration, and GraphQL.
### Workarounds
- Implement strict input validation at the Web Application Firewall (WAF) level.
- Disable unused GraphQL features or Gateway routes if immediate patching is not possible.
## Detection
- **Indicators of Compromise:** Unusual trace headers in logs, unexpected state transitions in application logic, or unauthorized routing patterns in Spring Cloud Gateway logs.
- **Detection methods and tools:** Use SCA (Software Composition Analysis) tools such as Snyk, OWASP Dependency-Check, or GitHub Dependabot to identify vulnerable library versions in your build manifest (pom.xml or build.gradle).
