CVE-2026-81694: openssl-encrypt before 1.4.9 Output Injection via Unsanitized Filenames in verify-usb Command

• Severity: low (CVSS 3.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-27 · updated 2026-10-29
• Weakness: CWE-117

Description

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 that repaint a forged PASSED verdict on screen, masking actual tamper detection. Fixed in 1.4.9 by routing drive-derived names through sanitize_for_display().
