Description

Vulnerability in Spring Cloud when substituting the profile parameter from a request made to the Spring Cloud Config Server configured to the native file system as a backend, because it was possible to access files outside of the configured search directories.This issue affects Spring Cloud: from 3.1.X before 3.1.13, from 4.1.X before 4.1.9, from 4.2.X before 4.2.3, from 4.3.X before 4.3.2, from 5.0.X before 5.0.2.

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.cloud:spring-cloud-config-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.springframework.cloud:spring-cloud-config-server to 4.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3qwq-q9vm-5j42 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
