CVE-2020-13956: Apache HttpClient incorrect handling of malformed authority component in request URIs
Severity: Medium Vendor: The Apache Software Foundation Versions Affected: Apache HttpClient 4.5.12 and prior Apache HttpClient 5.0.2 and prior Description: Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution. Mitigation: As of release 4.5.13 and 5.0.3 HttpClient will reject URIs with ambiguous malformed authority component as invalid. Users of HttpClient are advised to upgrade to version 4.5.13 or 5.0.3 and sanitize request URIs when using java.net.URI as input. Credit: This issue was discovered and reported by Priyank Nigam
