CWE-ID: CWE-305 - Authentication Bypass by Primary Weakness
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to wrong reuse of HTTP Negotiate authentication connection. A remote attacker can execute arbitrary requests under the wrong user context.
2) Exposure of Data Element to Wrong Session (CVE-ID: CVE-2026-5773)
CWE-ID: CWE-488 - Exposure of Data Element to Wrong Session
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper reuse of connection for SMB(S) transfers. A remote attacker can gain access to sensitive information on the system.
3) Insufficiently protected credentials (CVE-ID: CVE-2026-6253)
CWE-ID: CWE-522 - Insufficiently Protected Credentials
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain access to sensitive information on the system.
The vulnerability exists due to insufficiently protected credentials over redirect-to proxy. A remote attacker can gain access to sensitive information on the system.
4) Origin validation error (CVE-ID: CVE-2026-6276)
CWE-ID: CWE-346 - Origin Validation Error
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to origin validation error within stale custom cookie host. A remote attacker can gain access to sensitive information on the system.
5) Information disclosure (CVE-ID: CVE-2026-6429)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application when reused proxy connection. A remote attacker can gain unauthorized access to sensitive information on the system.
6) Authentication Bypass by Capture-replay (CVE-ID: CVE-2026-7168)
CWE-ID: CWE-294 - Authentication Bypass by Capture-replay
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to authentication bypass by capture-replay. A remote attacker can leak and reuse Digest proxy authentication state across proxies to impersonate the client.
7) Insufficiently protected credentials (CVE-ID: CVE-2026-8926)
CWE-ID: CWE-522 - Insufficiently Protected Credentials
CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to use credentials intended for another user.
The vulnerability exists due to insufficiently protected credentials in .netrc credential handling when processing a URL that specifies a username without a password. A remote user can supply a URL with a username that has no matching .netrc entry to use credentials intended for another user.
This issue occurs only when curl is configured to use a .netrc file and the target host has credentials stored for a different user.
