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...

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...

libcurl: libcurl: Information disclosure due to persistent Referer header

A flaw was found in libcurl. This vulnerability causes the HTTP Referer header to persist even after it has been explicitly cleared. This can lead to the previous referrer string being unintentionally reused and sent in subsequent requests, potentially disclosing sensitive information to unintend...

curl: libcurl: Information disclosure due to cookie leak when reusing connections with custom Host headers

A flaw was found in libcurl. This vulnerability allows for information disclosure when a custom Host: header is used in an initial HTTP request, and a subsequent request reuses the same connection without specifying a new Host: header. This can lead to libcurl incorrectly sending cookies intended...

curl: libcurl: Wrong file transfer due to incorrect SMB connection reuse

A flaw was found in libcurl. Due to a logical error in the connection reuse mechanism for SMB Server Message Block transfers, libcurl might reuse an existing SMB connection with a different share than intended. This vulnerability, categorized as CWE-488 Exposure of Data Element to Wrong Session,...

curl: libssh key passphrase bypass without agent set

A flaw was found in libcurl. When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent...
