CVE-2026-11347

Hardcoded Cryptographic Keys and Weak IV Generation in linqi

Published Jun 5, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
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.
