Summary

CVE-2026-70175 is a high-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 50th 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 IA-12 (Identity Proofing) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

IA-12 Identity Proofing partial match

Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.

IA-5 Authenticator Management partial match

Authenticator management requires secure distribution, reset, and verification procedures that directly address weak password recovery flows.

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.AA-01 partial match
blocks

Credential lifecycle management directly includes password reset/recovery flows.

PR.AA-02 partial match
blocks

Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.

PR.AA-03 partial match
blocks

Authentication policy covers strength/MFA but does not address recovery path weaknesses.

PR.PS-06 partial match
blocks

Secure SDLC reduces implementation flaws but is not specific to password-recovery design.
