CVE-2026-11347

Hardcoded Cryptographic Keys and Weak IV Generation in linqi

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.

CWE-321 Use of Hard-coded Cryptographic Key

The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered.

CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong.
