CVE-2025-10148 (GCVE-0-2025-10148)

Vulnerability from cvelistv5 – Published: 2025-09-12 05:10 – Updated: 2026-09-15 06:02

Title

predictable WebSocket mask

Summary

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.

Instead it used a fixed mask that\npersisted and was used throughout the entire connection.\n\nA predictable mask pattern allows for a malicious server to induce traffic\nbetween the two communicating parties that could be interpreted by an involved\nproxy (configured or transparent) as genuine, real, HTTP traffic with content\nand thereby poison its cache. That cached poisoned content could then be\nserved to all users of that proxy.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
