curl: HTTP/1.1 response framing violation and unsafe connection reuse when transfer decoding is disabled

Summary: libcurl can incorrectly reuse an HTTP/1.1 connection after a response containing both Content-Length and a non-chunked Transfer-Encoding when transfer decoding is disabled with CURLOPTHTTPTRANSFERDECODING = 0L --raw behavior. In this state, libcurl can treat Content-Length as the respons...

curl: Out-of-bounds read in curl_formadd when CURLFORM_NAMELENGTH is explicitly 0

Hi all, I've discovered a heap out-of-bounds read in curlformadd that causes libcurl to silently read past a caller-supplied buffer and transmit the leaked contents to the remote server. It's confirmed under ASan and reachable without violating any documented precondition. Impact An application...

curl: libcurl LDAP LDIF: entry DN and attribute names written without RFC 2849 base64 encoding, allowing server line injection

Summary: curl 8.22.0 base64-encodes LDAP attribute values that aren't RFC 2849 SAFE-STRINGs commit 2ba2fe3540, issue 22339, but the entry DN and the attribute names are still written to the LDIF output verbatim.

curl: CVE-2026-92390: -J no-clobber guarantee bypassed with 103 early hints

Hi all, I found a way for a server to defeat --remote-header-name's -J no-clobber guarantee: with curl -O -J -i, sending a 103 Early Hints before the final response or an ETag ahead of Content-Disposition under --etag-save lets a server overwrite an existing file it names via Content-Disposition,...

curl: CVE-2026-92389: TFTP direction confusion

Hi all, curl's TFTP state machine accepts either direction's opening response regardless of which one was requested. A malicious TFTP server can answer an RRQ with ACK block 0, which flips curl into transmit mode and causes it to drain whatever read source the handle's sticky CURLOPTREADDATA poin...

curl: CVE-2026-92386: server-set cookie aborts cookie jar load

Hi all, I found a way for a remote server to poison a shared cookie jar so that later, unrelated transfers fail before any network I/O happens. It just has to send a Set-Cookie that curl happily accepts but can never read back from its own jar file. The bug parsecookieheader accepts a Set-Cookie...

curl: TELNET control and environment data bypass HTTPS-proxy TLS

Hi, I found a way to make libcurl send TELNET credential and environment data in cleartext to a TELNET origin, even when the connection is supposedly protected by an HTTPS proxy tunnel. The tunnel's TLS never sees it. The bug For telnet:// routed through an HTTPS proxy, generic connection setup...

curl: Socket API drops expired timeouts for transfers queued behind a connection limit

Hi all, I found a way to make libcurl silently and permanently drop a transfer's CURLOPTTIMEOUTMS/CURLOPTCONNECTTIMEOUTMS deadline. It happens when that transfer is queued behind a connection-count limit and the application drives libcurl through the event-driven curlmultisocketaction API instead...

curl: One Strict-Transport-Security response header empties the victim's entire HSTS store, silently,

Summary One Strict-Transport-Security response header, from any HTTPS server the victim contacts, leaves the victim's on-disk HSTS store at zero bytes. Every host in it loses HSTS protection, including hosts unrelated to the server that sent the header. curl exits 0 and prints nothing. Two...
