Summary

CVE-2026-81694 is a critical-severity Improper Output Neutralization for Logs (CWE-117) vulnerability in Jahlives Openssl Encrypt. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Indicator Removal (T1070); ranked at the 8th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

openssl-encrypt (pip package, versions <= 1.4.8) fails to sanitize filenames read from untrusted drive data (outside the AES-GCM authenticated manifest) before printing them in the verify-usb command's output. An attacker can plant filenames containing terminal cursor-movement and erase-line control bytes…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect output neutralization when log messages are constructed from untrusted input.

Input validation reduces the chance that specially crafted data reaches log-message construction routines.

PR.PS-06 partial match
prevents

Secure SDLC practices and coding standards directly require output sanitization for logs.

A.8.15 Logging partial match
degrades

Logging control directly requires proper log generation and handling, which mitigates improper output neutralization.

finds

Monitoring activities rely on trustworthy logs but do not ensure log message integrity.

prevents

Secure SDLC includes coding standards that reduce log-related weaknesses but does not specifically address logging.

prevents

Secure coding practices mandate input validation and output encoding, directly preventing log injection.

finds

Security testing can detect log injection flaws but does not prevent them at the source.
