AI Analysis
Technical Summary
CVE-2026-12064 is a vulnerability in curl shipped with Red Hat Hardened Images where invoking curl with a schemeless URL and specifying SFTP or SCP as the default protocol causes the tool layer to skip initializing essential SSH security options. This results in bypassing SSH host verification, allowing curl to connect to unverified SSH remote hosts without alerting the user. This flaw can lead to man-in-the-middle attacks enabling data interception or manipulation. Red Hat has acknowledged this issue with a CVSS v3.1 base score of 7.5 (high severity) and advises mitigation by explicitly specifying the protocol in URLs rather than relying on --proto-default options. Updated RPM packages including curl 8.21.0-0.1.hum1 have been released as part of a broader security advisory for Red Hat Hardened Images RPMs. No known exploits in the wild have been reported. The vendor advisory does not explicitly confirm a patch but provides updated packages and mitigation guidance.
Potential Impact
The vulnerability allows attackers to bypass SSH host verification in curl when used with schemeless URLs and default protocols set to SFTP or SCP. This can enable man-in-the-middle attacks, potentially allowing interception or manipulation of data transmitted over SSH connections without user awareness. The impact is limited to scenarios where curl is invoked with these specific options and URL formats.
Mitigation Recommendations
Red Hat advises avoiding the use of the --proto-default sftp or --proto-default scp options with schemeless URLs when invoking curl. Instead, users should explicitly specify the protocol in the URL (e.g., sftp://host/path or scp://host/path). Updated RPM packages including curl 8.21.0-0.1.hum1 have been released as part of the Red Hat Hardened Images update. Users should apply these updates following Red Hat's guidance at https://images.redhat.com/. Patch status is not explicitly confirmed; check the vendor advisory for current remediation guidance.
