CVE-2025-5025

No QUIC certificate pinning with wolfSSL

Published: May 28, 2025Updated: Jul 30, 2025 Sources: CVE List NVD BDUCWE-295

4.8MEDIUM

Description

libcurl supports *pinning* of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. Documentation says the option works with wolfSSL, failing to specify that it does not for QUIC and HTTP/3. Since pinning makes the transfer succeed if the pin is fine, users could unwittingly connect to an impostor server without noticing.
