CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 0CVE-2025-5025 – No QUIC certificate pinning with wolfSSL
https://notcve.org/view.php?id=CVE-2025-5025
28 May 2025 — 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. • https://curl.se/docs/CVE-2025-5025.html •

28 May 2025 — libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks. • https://curl.se/docs/CVE-2025-4947.html •

https://notcve.org/view.php?id=CVE-2025-0167
05 Feb 2025 — When asked to use a `.netrc` file for credentials **and** to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has a `default` entry that omits both login and password. A rare circumstance.
