CVE-2025-68948

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. This allows the attacker to retrieve the AccessAuthCode in plain text and potentially authenticate or take over the session.

Recommendations Update to a version later than 3.5.1.
