- CVE-2026-19931 CRITICAL CVSS 9.8 haxx / curl
NVD: A flaw in libcurl makes it wrongly reuse an HTTP connection setup for a given hostname using Negotiate authentication, when the initial request is done using empty credentials. NVD: This can make user B's request get sent over user A's previously authenticated connection. OSV: Negotiate ambient user conn reuse

- CVE-2026-86219 CRITICAL CVSS 9.8 -
NVD: Authen::SASL::Perl::DIGEST_MD5 versions before 2.2100 for Perl accept replayed authentication responses via unverified nonce in server_step. NVD: server_start generates a fresh nonce and sends it in the challenge, and nothing later compares that value against the nonce the client returns. NVD: server_step derives the expected digest from the client's own parameters, so a response verifies whenever its digest matches the nonce it carries.

- CVE-2026-18924 CRITICAL CVSS 9.1 haxx / curl
NVD: A flaw in libcurl's handling of HTTP/2 Server Push streams, when the parent handle is set to share connections with other handles, can lead to use-after-free in the cleanup process.

- CVE-2026-82209 HIGH CVSS 8.2 haxx / curl
NVD: When libpsl support is enabled, libcurl fails to enforce the Public Suffix List boundary check when processing a Set-Cookie header where the Domain attribute explicitly matches an origin host that is itself a public suffix (e.g., Domain=co.uk set by co.uk). NVD: Instead of coercing it into a strict host-only cookie, libcurl saves the cookie with wildcard domain scope (.co.uk). NVD: Consequently, the cookie is inappropriately included in subsequent outbound requests or HTTP redirects to arbitrary sibling subdomains under the same public suffix (e.g., attacker.co.uk).

- CVE-2026-80231 HIGH CVSS 7.5 haxx / curl
NVD: A flaw in libcurl makes it wrongly reuse an existing HTTPS connection setup for a given hostname even when using a different Native CA Store setting (CURLSSLOPT_NATIVE_CA) than when the connection was created. OSV: native CA store conn reuse OSV: A flaw in libcurl makes it wrongly reuse an existing HTTPS connection setup for a given hostname even when using a different Native CA Store setting (CURLSSLOPT_NATIVE_CA) than when the connection was created.

- CVE-2026-80229 HIGH CVSS 7.5 haxx / curl
NVD: When performing transfers via libcurl’s multi interface, pooled TLS connections can outlive their originating easy handles. NVD: In OpenSSL 3 provider configurations, libcurl attaches an allocated library context to the easy handle's state and passes it to OpenSSL without acquiring an ownership reference; destroying the easy handle prematurely frees this context while the active... OSV: OpenSSL provider use-after-free

- CVE-2026-80255 HIGH CVSS 7.5 haxx / curl
NVD: A Set-Cookie: header using tab (horizontal tab, ASCII code 9) instead of space (ascii code 32) immediately before the Secure attribute causes curl to store the cookie without its Secure flag. NVD: The cookie might then wrongfully be sent over plaintext HTTP on subsequent requests to the same host. OSV: secure cookie attribute bypass with tab

- CVE-2026-80230 HIGH CVSS 7.5 haxx / curl
NVD: When CURLOPT_PINNEDPUBLICKEY is configured alongside options that disable standard peer verification (CURLOPT_SSL_VERIFYPEER = 0 and CURLOPT_SSL_VERIFYHOST = 0), libcurl fails to enforce public key pinning on connections established without a presented server... NVD: Bypassing the pinning check under these disabled-verification conditions allows unauthenticated connections to succeed when they should be rejected. OSV: OpenSSL pinning bypass

- CVE-2026-82208 HIGH CVSS 7.5 haxx / curl
NVD: With the wolfSSL backend, when CA caching is enabled and an CURLOPT_SSL_CTX_FUNCTION callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. NVD: A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectly accepted. OSV: wolfSSL CA-cache hit overrides callback
