Credential disclosure via hardcoded keys and weak IVs
Published Jun 5, 2026 · Updated Jun 5, 2026
Cryptographic flaws in linqi 1.4.8.5 and earlier allow local users to decrypt sensitive configuration values and database credentials. The application embeds cryptographic keys and generates AES/CBC initialization vectors from a limited ASCII character set, enabling known-plaintext recovery. Local access with low privileges is required; recovered ConnectionString values can expose database credentials from appsettings.json.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
