curl: curl: Insecure connection establishment due to TLS configuration mismatch
A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
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...
libcurl: libcurl: Security feature bypass due to improper mTLS connection reuse
A flaw was found in curl. The libcurl library, used for transferring data with URLs, could improperly reuse existing network connections. This occurred even when changes to mutual Transport Layer Security mTLS settings, particularly those for client certificates, should have prevented such reuse...
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: 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: 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: 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: libcurl: Improper certificate validation due to cached TLS settings reuse
A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...
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: Information disclosure via incorrect .netrc password lookup
A flaw was found in curl. When curl is configured to use a .netrc file for credentials and a URL is provided with a username but no password, curl may incorrectly retrieve and use the password for a different user from the .netrc file for the same host. This could lead to unauthorized information...
curl: curl: Information disclosure via incorrect Digest authentication header reuse
A flaw was found in curl. When libcurl performs a transfer to an HTTP origin using Digest authentication and then reuses the same connection handle for a subsequent transfer to a different origin, it may incorrectly send the authentication header intended for the first origin to the second. This...
curl: Information disclosure due to uncleared proxy authentication state
A flaw was found in libcurl. When reusing a libcurl handle for sequential transfers with environment-variable proxy configuration, the library does not properly clear the proxy authentication state. This oversight can lead to the unintended disclosure of Proxy-Authorization headers to an incorrec...

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...
libcurl: libcurl: Information disclosure due to failure to clear proxy authentication credentials
A flaw was found in curl. When libcurl is instructed to clear proxy authentication credentials, it fails to do so, leaving the old credentials available. This could lead to the unintended reuse of sensitive proxy authentication credentials for subsequent network transfers, potentially resulting i...
FreeRDP: FreeRDP: Remote code execution or client crash via malicious TS Gateway
A flaw was found in FreeRDP. FreeRDP clients using TS Gateway are vulnerable to a heap-buffer-overflow. A malicious gateway can send a specially crafted response fragment, causing the client to write beyond its allocated buffer. This can lead to a client crash, resulting in a Denial of Service Do...
