CVE-2025-10148
5.3 · MEDIUMOverview
CVE-2025-10148 is a medium-severity vulnerability affecting haxx curl. It was published on September 12, 2025 and has a CVSS 3.1 base score of 5.3 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
curl's websocket code did not update the 32 bit mask pattern for each new
outgoing frame as the specification says. Instead it used a fixed mask that
persisted and was used throughout the entire connection.
A predictable mask pattern allows for a malicious server to induce traffic
between the two communicating parties that could be interpreted by an involved
proxy (configured or transparent) as genuine, real, HTTP traffic with content
and thereby poison its cache. That cached poisoned content could then be
served to all users of that proxy.
Remediation
Check the references section for vendor advisories and patches from haxx. Update curl to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
