curl: CVE-2026-5545: wrong reuse of HTTP Negotiate connection

Summary: An attacker sharing a libcurl multi-handle connection pool can hijack another user's Negotiate/Kerberos-authenticated connection. When User A authenticates via Negotiate SPNEGO and the connection returns to the pool, User B using CURLAUTHANY with different credentials gets that connectio...

curl: Use-After-Free race condition in url_move_hostname() via shared connection pool

Summary: In lib/url.c, urlconnreuseadjust calls urlmovehostname which frees conn-host.rawalloc and conn-host.encalloc via Curlsafefree and Curlfreeidnconvertedhostname after Curlcpoolfind has already released the connection pool lock. A second thread doing a concurrent pool lookup still holds tha...

curl: HTTP/2 PUSH_PROMISE header loss on OOM bypasses scheme validation (regression of 2e8c922a89)

Summary: In lib/http2.c:1490, when curlmaprintf fails due to memory pressure, the push promise header is silently dropped but the callback returns success. If the lost header is the :scheme pseudo-header, the security check at line 733 that blocks HTTPS pushes over insecure connections is skipped...

curl: Unbounded GZIP Decompression Leading to Event-Loop Starvation

When libcurl is configured to decompress HTTP responses via CURLOPTACCEPTENCODING or the --compressed CLI flag, it lacks decompression bounds checking or a mechanism to yield execution during massive expansion tasks. If an attacker provides a highly compressed payload zip bomb, libcurl's underlyi...

curl: HTTP/2 server push accepts a non-authoritative :scheme=https over cleartext h2c, enabling HTTPS cache-key poisoning

Summary: I found that libcurl 8.19.0 accepts an HTTP/2 pushed stream on a cleartext h2c connection even when the server sends :scheme=https in PUSHPROMISE. In lib/http2.c, settransferurl builds the pushed handle URL from the server-supplied :scheme, :authority, and :path, but PUSHPROMISE validati...
