GHSA-8h53-fjgg-g42g · Severity: medium · Ecosystem: maven — Insufficient Verification of Data Authenticity in Async Http Client
Async Http Client (aka AHC or async-http-client) before 1.9.0 skips X.509 certificate verification unless both a keyStore location and a trustStore location are explicitly set, which allows man-in-the-middle attackers to spoof HTTPS servers by presenting an arbitrary certificate during use of a typical AHC configuration, as demonstrated by a configuration that does not send client certificates.
Conclusion & alert: CVE-2013-7397 is rated Low Risk (37.4/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 0.99%). Mandatory action: Monitor for updates and reassess as exploit intelligence or EPSS changes.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
