Description

This security bulletin contains information about 1 security vulnerability.


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

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.


Remediation

Install update from vendor's website.
