Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

In Spring Data REST versions 3.4.0 - 3.4.13, 3.5.0 - 3.5.5, and older unsupported versions, HTTP resources implemented by custom controllers using a configured base API path and a controller type-level request mapping are additionally exposed under URIs that can potentially be exposed for unauthorized access depending on the Spring Security configuration.

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.data:spring-data-rest-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.springframework.data:spring-data-rest-core to 3.4.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4926-qpxg-6r3w is resolved across your whole dependency graph.

  3. Workarounds

    Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
