Summary

CVE-2026-74873 is a high-severity Invocation of Process Using Visible Sensitive Information (CWE-214) vulnerability. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data

openssl_encrypt versions before 1.4.0 expose passwords passed via the --password CLI argument in process listings accessible to all system users. Attackers can read process arguments through ps aux or /proc/[pid]/cmdline to retrieve plaintext passwords and keystore passwords.

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.DS-10 mostly match
prevents

Explicit example of removing confidential data from process listings directly prevents visible sensitive arguments.

PR.PS-06 mostly match
prevents

Secure SDLC practices include avoiding exposure of secrets via command lines or environment variables.

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.8.18 Use of privileged utility programs partial match
degrades

Restricting privileged utility programs reduces the chance that sensitive invocation data is exposed to other processes.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights reduce exposure of sensitive command-line arguments to unauthorized observers.

A.8.28 Secure coding partial match
prevents

Secure coding practices can prevent passing sensitive data via command-line arguments or environment variables.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits visibility of process arguments and environment variables to authorized users only.
