CVE-2026-92391 curl_mime_free stack overflow by recursion

A deeply nested multipart MIME structure constructed via the public API causes a stack overflow in libcurl during normal cleanup operations. An excessive recursion depth within curlmimefree leads to unbounded stack frame allocation during structure traversal, ultimately crashing the host process...

CVE-2026-103672 HMS Networks PEAK-System PCAN Windows drivers Improper Validation of Array Index

The PEAK-System PCAN parser indexes a length table using attacker-controlled DLC without enforcing DLC = 0x0f, then copies attacker payload from record+0x1c into a fixed-size stack destination...

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

When invoked with --remote-header-name -J, curl fails to preserve its documented anti-clobbering protection if an intermediate 103 Early Hints response precedes the final HTTP response, or if an ETag header is processed before Content-Disposition under --etag-save. This flaw allows an HTTPS serve...

CVE-2026-92389 TFTP direction confusion

libcurl's TFTP state machine fails to validate state transitions against the requested transfer direction, accepting opening server responses for both reads and writes interchangeably. A malicious TFTP server can respond to a download request in a way that forces the client into transmit mode,...

CVE-2026-92388 FTP wildcard write callback mixup

When an FTP wildcard LIST operation fails, libcurl omits the restoration path meant for successful listings, leaving the write callback set to the internal listing parser and the write callback data pointing directly to the easy handle. Subsequent reuse of this handle triggers an immediate crash,...

CVE-2026-92387 never-ending loop via server response omission

By permanently omitting the final control-response line, a malicious FTP, IMAP, POP3, or SMTP server can exploit libcurl and completely bypass its configured transfer timeout mechanism, indefinitely blocking all concurrent transfers bound to the same multi-handle...

CVE-2026-101103 HMS Networks PEAK-System PCAN Windows drivers Classic Buffer Overflow

The PEAK-System PCAN diagnostic call did not validate that the caller-supplied output buffer was large enough to hold the output record...

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

When writing a long cookie name and value to a Netscape cookie jar, a remote HTTP server can make curl write a record that exceeds its line-length parsing limit. Consequently, any subsequent curl invocation reading from that same cookie jar using --cookie silently aborts parsing prematurely upon...

CVE-2026-87866 wolfSSL public-key pinning bypass

When built with wolfSSL, curl can successfully validate a pinned public key hash against a key the TLS peer does not possess. During the TLS handshake, wolfSSL validates the connection, but curl's subsequent re-parsing of the same certificate - tricked by a manipulated validity length field -...

CVE-2026-109576 HMS Networks PEAK-System PCAN Windows drivers Out-of-bounds Write

The parser in PEAK-System PCAN driver correctly detected the malformed record, but the loop iterating the record list advanced its processed-bytes counter even when a record had been rejected as invalid...

CVE-2026-87865 knownhost callback mismatches key as missing

When libcurl uses libssh2 with a hashed knownhosts file, an unrelated initial entry can cause host key validation to report a key mismatch as a missing key to the CURLOPTSSHKEYFUNCTION callback...

CVE-2026-87863 HSTS response erases persisted entries

An authenticated HTTPS origin can supply an HSTS max-age value that the parser accepts, but time serialization later fails to process. On 64-bit systems, extreme max-age values compute an absolute expiry within standard time integer limits that exceeds calendar time structure bounds. During cache...

CVE-2026-87864 IMAP APPEND plus CRLF conversion command injection

Enabling CURLOPTCRLF causes curl to advertise the raw input byte count in the IMAP APPEND N literal while transmitting line-ending expanded data. The server reads only $N$ bytes for the payload, causing the remaining overflow bytes to be interpreted and executed as pipelined IMAP commands within...

CVE-2026-87862 HSTS cache import drops longer-lived child

Importing a includeSubDomains parent HSTS entry before a longer-lived child entry, silently drops the child. Consequently, when the parent expires, the child's valid HSTS policy is lost, causing curl to issue unencrypted HTTP requests rather than upgrading to HTTPS...

CVE-2026-87861 cross-origin reuse of a Negotiate connection

When using ambient user credentials, an HTTP request directed to one origin may be dispatched over a connection previously authenticated via Negotiate for a different origin, leaving the request's intended credentials unused...

CVE-2026-86415 auto client cert connection reuse mixup

libcurl's connection cache match function never considers the automatic client certificate option, so a cached, already authenticated Schannel connection can be handed to a transfer that got redirected to a different origin, even though the code explicitly switched off the auto client cert option...

CVE-2026-86414 leaking host credentials to HTTP proxy

An HTTP proxy can trick libcurl into sending the origin's credentials Basic password, or a Negotiate/Kerberos ticket to the proxy itself, by answering the CONNECT tunnel request with 401 WWW-Authenticate: instead of the expected 407 Proxy-Authenticate:...

CVE-2026-86413 Negotiate credentials sent to redirected origin

When using an ambient user in a first transfer doing Negotiate authentication and asked to follow redirects, curl could pass on its credential details to an unrelated second origin when asked to redirect there...

CVE-2026-112380 Missing authorization in the WhatsApp channel in Kiro Crew

Missing authorization in the WhatsApp group channel in Kiro Crew might allow a remote actor who is a member of an operator-configured WhatsApp group to control the operator's other agent sessions and execute arbitrary commands on the host running Kiro Crew via messages sent to the group. To...

CVE-2026-86412 server-set cookie erases cookie jar

A remote HTTP server can set a cookie that curl accepts and writes to a Netscape cookie jar but cannot reload. On the next invocation using the same path for --cookie and --cookie-jar, curl fails before connecting, then the cleanup procedure replaces the jar with an empty file, deleting cookies f...

CVE-2026-86411 FTP connection reuse inherits client-certificate

An ftp:// transfer configured with CURLUSESSLNONE can reuse a pooled FTP control connection that a previous easy handle upgraded with STARTTLS and authenticated using a client certificate. The second handle performs neither a new TLS handshake nor a new FTP login, so the server continues to...

CVE-2026-86410 redirect to SFTP or SCP bypasses host verification

A flaw in the curl command line tool's logic makes it only set SSH host verification options when interacting directly using SFTP or SCP, and not as a result of following a redirect...

CVE-2026-86409 stale SigV4 headers sent unintended

Setting CURLOPTAWSSIGV4 to NULL but does not disable SigV4 authentication, contrary to expectations and documentation. A subsequent transfer on the same handle still sends an Authorization: AWS4-HMAC-SHA256 header to whatever URL isset next, leaking state information...
