Aware2: Cleartext Transmission of Sensitive Information
CVE-2026-55396 is a high-severity cleartext transmission of sensitive information vulnerability in Aware2 from Teledyne FLIR, with a CVSS 4.0 base score of 8.5 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected Aware2 versions: 6.9.0.2 and earlier; 1.7.9 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.11% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
Cleartext transmission without a cryptographic integrity check in operator control unit to robot UDP traffic in Teledyne FLIR Aware2 versions through 6.9.0.2 (PackBot) and 1.7.9 (FirstLook) allows adjacent unauthenticated attackers to intercept, hijack, or modify control traffic against Teledyne FLIR PackBot and FirstLook robots running this software via sniffing or hijacking network traffic.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
