CVE-2020-7650Network attack vector

Arbitrary file reads via permissive proxy allowlist

Published May 29, 2020 · Updated Aug 4, 2024

Path traversal in Snyk Broker 4.72.0 through 4.73.0 allows remote authenticated users to read arbitrary JSON and YAML files through proxied requests. The affected client templates authorize wildcard repository-content paths based only on a .json, .yaml, or .yml suffix, so crafted paths pass the request allowlist. Access to the private Broker tunnel is required, and exploitation exposes matching files readable with the configured integration credentials.
