CVE-2026-109576Medium· 5.5HMS 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-2026-87861Critical· 9.1PoCcross-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-2026-86415High· 7.5auto 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 …
CVE-2026-86414Critical· 9.1PoCleaking 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 40…
CVE-2026-87864High· 8.1PoCIMAP APPEND plus CRLF conversion command injection
Enabling `CURLOPT_CRLF` 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 byte…
CVE-2026-87863High· 8.1PoCHSTS 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 li…
CVE-2026-87862High· 8.1PoCHSTS 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 …
CVE-2026-92386High· 8.1PoCserver-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 coo…
CVE-2026-87866Critical· 9.1PoCwolfSSL 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 certif…
CVE-2026-87865High· 7.4PoCknownhost callback mismatches key as missing
When libcurl uses libssh2 with a hashed `known_hosts` file, an unrelated initial entry can cause host key validation to report a key *mismatch* as a *missing* key to the `CURLOPT_SSH_KEYFUNCTION` callback.
CVE-2026-92387High· 8.1PoCnever-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 boun…

CVE-2026-101103Medium· 5.5HMS 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-2026-92389High· 8.1PoCTFTP 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 re…
CVE-2026-92388Critical· 9.1PoCFTP 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…

CVE-2026-92390High· 7.5PoC-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 `C…
CVE-2026-103672High· 7.1HMS 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-2026-92391High· 7.5PoCcurl_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 `curl_mime_free` leads to unbounded stack frame allocation d…
