CVE-2026-81707: Improper Input Validation in jahlives openssl_encrypt

0
Critical
VulnerabilityCVE-2026-81707cvecve-2026-81707
Published: 08/27/2026 (08/27/2026, 14:51:09 UTC)
Source: CVE Database V5
Vendor/Project: jahlives
Product: openssl_encrypt

Description

openssl_encrypt before 1.4.9 fails to sanitize the email field of imported identity documents, allowing attackers to inject ANSI escape sequences that forge the fingerprint verification line displayed to users. Attackers can deliver a crafted identity bundle through normal contact-exchange flows or keyserver responses to manipulate terminal output and display a fraudulent fingerprint, bypassing the out-of-band verification mechanism that protects against key substitution attacks.
