Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : curl vulnerabilities (USN-8227-1)
The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8227-1 advisory. It was discovered that curl incorrectly reused non-TLS connections when TLS was required in some STARTTLS configurations....

When asked to both use a .netrc file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname but...

When an OAuth2 bearer token is used for an HTTPS transfer, and that transfer performs a redirect to a second URL, curl could leak that token to the second hostname under some circumstances. If the hostname that the first request is redirected to has information in the used .netrc file, with eithe...

curl: libcurl: Credential leak via reused proxy connection during HTTP redirects
A flaw was found in libcurl. When configured to use a .netrc file for credentials and follow HTTP redirects, libcurl can inadvertently send the password from the initial connection to the redirected host. This sensitive information disclosure occurs when both the original and redirect URLs use...
libcurl 7.14.0 < 8.20.0 Netrc Password Leak on HTTP Redirect
The version of libcurl installed on the remote host is 7.14.0 prior to 8.20.0. It is, therefore, affected by a netrc password leak vulnerability: - When asked to both use a .netrc file for credentials and to follow HTTP redirects, libcurl could leak the password used for the first host to the...

Insertion of Sensitive Information Into Sent Data
Overview Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data via the reuse of a proxy connection during HTTP redirects when using .netrc for credentials. An attacker can obtain sensitive credential information by intercepting traffic if both the...
curl: libcurl omits IPv6 zoneid from host identity and leaks credentials/cookies across scoped link-local realms
Summary: libcurl omits the IPv6 zoneid component from multiple security-sensitive host identity decisions even though the connection layer still routes by zoneid. As a result, two distinct scoped/link-local destinations such as fe80::X%zoneA and fe80::X%zoneB are treated as the same host by...
curl: Digest Auth State Leak on Cross-Origin Redirect via Netrc - Username and Password Hash Sent to Wrong Host
Summary When curl follows an HTTP redirect from hostA to hostB using --netrc --digest -L, Digest authentication state nonce, realm from hostA persists and is combined with hostB's netrc credentials to generate an unsolicited Digest Authorization header sent to hostB. This leaks hostB's username i...
curl: CVE-2026-6429: netrc credential leak with reused proxy connection
Summary: libcurl can leak .netrc-derived host Authorization credentials across redirected hosts when an HTTP proxy connection is reused. In the PoC, .netrc contains credentials only for a.test, but after a.test redirects to b.test and then c.test over the same keep-alive proxy connection, libcurl...
