Summary

CVE-2026-92088 is a high-severity Improper Handling of Undefined Values (CWE-232) vulnerability in Upkeeper (inferred from references). Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 3th 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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation partial match

Input validation directly rejects or sanitizes undefined/unsupported parameter values before they reach processing logic.

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 partial match
blocks

Secure SDLC practices directly require proper input validation and error handling for undefined values.

A.8.19 Installation of software on operational systems partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development life cycle requires handling of invalid/undefined inputs during design and coding.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against injections or input validation) be identified and specified during development or acquisition; it does not itself enforce, implement or prevent the undefined-value handling flaw from being introduced or exploited.

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

A.8.27 mandates security-by-design principles (e.g. least privilege, fail securely, distrust external input, security-oriented design reviews) that reach some but not most instances of mishandling undefined values; the weakness can still be introduced in code that follows the principles but is incomplete on parameter validation or state handling.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require defensive checks for undefined or unsupported parameter values.

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

Security testing in development can detect missing handling of undefined values before release.
