CVE-2026-50210 · Severity: info · CVSS 6.9 · Published 2026-06-04

The Acer Connect M6E 5G portable router uses a weak encryption method that relies on static, predictable values. This flaw could allow an attacker to replay intercepted data or potentially decrypt sensitive information transmitted by the device. This compromises the privacy of the data being sent through the router and could lead to unauthorized access to communications.

**Am I affected by CVE-2026-50210?** Check whether you run Acer Connect M6E 5G Portable WiFi Router at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

The device implements AES encryption in Cipher Block Chaining (CBC) mode using a static, zero-filled Initialization Vector (IV). In CBC mode, the IV should be unique and unpredictable for every encryption operation to ensure that identical plaintexts result in different ciphertexts. By using a fixed IV, the implementation becomes vulnerable to replay attacks and known-plaintext attacks, allowing an attacker to potentially decrypt traffic or manipulate data streams. The vulnerability is identified as CVE-2026-50210 and affects firmware versions up to M6E_AI_1.00.000019.
