The fix applies to HTTP clients created by the RestClient builder; applications that supply their own HttpClient must disable automatic redirects or strip credential headers on cross-origin redirects themselves.\n\n## Affected\n\n- `org.apache.juneau:juneau-rest-client < 9.2.1`\n- `org.apache.juneau:juneau-rest-common < 9.2.1`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":55,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
