What is CVE-2026-11347?
CVE-2026-11347 is a high-severity vulnerability in linqi, published on 5 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
