Name of the Vulnerable Software and Affected Versions SiYuan versions prior to 3.5.1

Description SiYuan Note application uses a hardcoded cryptographic secret for its session store, making session encryption ineffective. The AccessAuthCode, stored in the session cookie, can be decrypted by an attacker who obtains the encrypted session cookie.
