CRITICAL 9.8

openssl_encrypt before 1.4.9 ANSI Escape Injection via Identity Email

CVSS Score

9.8

EPSS Score

0.0%

EPSS Percentile

0th

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.
