CVE-2026-11347

The linqi application contains hardcoded cryptographic keys.

HIGH 8.5EPSS 0.07%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The linqi application contains hardcoded cryptographic keys. Additionally, the application uses a weak algorithm with a limited ASCII charset to dynamically generate Initialization Vectors (IVs) for AES/CBC encryption, making known-plaintext attacks feasible. An attacker with local access can leverage these vulnerabilities to decrypt sensitive obfuscated strings, including ConnectionString values containing database credentials from appsettings.json.
