CVE-2026-54068: CWE-306: Missing Authentication for Critical Function in siyuan-note siyuan
SiYuan versions prior to 3.7.0 have a vulnerability in the /api/icon/getDynamicIcon endpoint, which is excluded from authentication. This allows unauthenticated attackers who know a valid block ID to execute arbitrary SELECT queries on the SQLite database, potentially exposing all user note content and metadata. The issue is fixed in version 3.7.0.
AI Analysis
Technical Summary
SiYuan, an open-source personal knowledge management system, has a missing authentication vulnerability (CWE-306) in the /api/icon/getDynamicIcon endpoint prior to version 3.7.0. This endpoint is explicitly excluded from authentication checks. When called with specific parameters, it invokes a Go template rendering function that executes arbitrary SELECT SQL queries via querySQL and queryBlocks functions against the SQLite database. An unauthenticated attacker with knowledge of a valid block ID can exfiltrate sensitive user data including notes, tags, asset references, and block attributes. The vulnerability is resolved in version 3.7.0.
Potential Impact
An unauthenticated network-adjacent attacker can access and exfiltrate all user note content, tags, asset references, and block attributes stored in the SiYuan SQLite database by exploiting this endpoint. The confidentiality of user data is compromised. There is no impact on integrity or availability reported.
Mitigation Recommendations
This vulnerability is fixed in SiYuan version 3.7.0. Users should upgrade to version 3.7.0 or later to remediate this issue. No official patch or temporary fix details are provided beyond this version upgrade. Since this is not a cloud service, remediation depends on user action to update the software.
