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

What is CVE-2026-81694?

CVE-2026-81694 is a critical vulnerability in Jahlives Openssl Encrypt, published on 27 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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().
