curl: curl: Proxy credential disclosure via redirects to unauthenticated proxies
A flaw was found in curl. When curl is configured to use distinct proxies for different URL schemes, a redirect from a URL using an authenticated proxy to one using an unauthenticated proxy can inadvertently expose the initial proxy's credentials. This improper credential management CWE-522 may...
curl: curl: SSH host verification bypass when using schemeless URLs with SFTP/SCP
A flaw was found in curl. When a user invokes curl with a schemeless URL and specifies SFTP SSH File Transfer Protocol or SCP Secure Copy Protocol as the default protocol, the tool layer fails to initialize critical SSH security options. This bypasses host verification, allowing curl to connect t...
curl: libcurl: Unauthorized connection reuse due to a logical error
A flaw was found in libcurl. A logical error in the connection pooling mechanism may cause libcurl to reuse an authenticated connection for an unintended service. This could allow an application to wrongfully reuse an existing connection to the same server that was authenticated for a different...
curl: curl: Cookie injection via malicious HTTP server using super cookies
A flaw was found in curl's cookie parsing logic. A malicious HTTP server can exploit this by setting 'super cookies' that bypass the Public Suffix List check. This allows an attacker-controlled origin to inject cookies that curl then transmits to unrelated third-party domains, leading to...
curl: curl: Authentication bypass due to incorrect connection reuse with Negotiate authentication
A flaw was found in curl. When an application uses libcurl to make multiple Negotiate-authenticated HTTP or HTTPS requests to the same server with different credentials, libcurl may incorrectly reuse an existing connection. This logical error can cause a subsequent request to be sent using the...
curl: curl: Information disclosure via OAuth2 bearer token leakage during HTTP(S) redirect
A flaw was found in curl. When an OAuth2 bearer token is used for an HTTPS transfer that redirects to a second URL, curl could unintentionally leak the token. This occurs if the second hostname has entries in the .netrc file, allowing the bearer token intended for the first host to be sent to the...
curl: curl: Man-in-the-middle attack via SSH host key bypass
A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
curl: curl: Unauthorized access due to improper HTTP proxy connection reuse
A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

curl 7.7 through 7.76.1 suffers from an information disclosure when the -t command line option, known as CURLOPTTELNETOPTIONS in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEWENV variables, libcurl could be made to pass on...

curl can be told to parse a .netrc file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause ...
