Summary

CVE-2025-22870 is a medium-severity Misinterpretation of Input (CWE-115) vulnerability in Go (inferred from references). Its CVSS base score is 4.4 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Masquerading (T1036); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly stops the system from accepting and acting on misinterpreted data values.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require correct input parsing/validation to avoid misinterpretation flaws.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect input misinterpretation flaws but does not itself implement the preventive controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and canonicalization that directly prevent misinterpretation of inputs.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for robust input handling and sanitization to avoid misinterpretation.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include defensive input processing and error handling that reduce misinterpretation risks.

A.8.28 Secure coding partial match
prevents

Secure coding standards require strict input validation and canonical forms to eliminate misinterpretation vulnerabilities.
