Description

This security bulletin contains information about 1 vulnerability.


1) Improper Certificate Validation (CVE-ID: CVE-2026-32627)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to intercept HTTPS connections and disclose sensitive information.

The vulnerability exists due to improper certificate validation in ClientImpl::create_redirect_client() in httplib.h when following an HTTPS redirect through a configured proxy. A remote attacker can return a crafted redirect response and present a forged or self-signed certificate to intercept HTTPS connections and disclose sensitive information.

Only builds with SSL support are affected, and exploitation requires the client to have a proxy configured with redirect following enabled.
