password leak in CURLINFO_EFFECTIVE_URL
libcurl could accidentally return a URL for curleasygetinfo's CURLINFOEFFECTIVEURL option containing credentials, even though neither the URL provided to libcurl nor the redirected URL did...

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...

-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...

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...
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,...
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...
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...
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 -...

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...

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,...
