No patch
|
| CVE-2026-29073 | SQL injection in SiYuan prior to version 3.6.0 allows any authenticated user, including those with read-only access, to execute arbitrary database queries through the /api/query/sql endpoint due to insufficient authorization checks. Public exploit code exists for this vulnerability, enabling attackers to extract sensitive data or modify the knowledge base contents. No patch is currently available for affected versions. | HIGH | 8.8 | 0.1% | 64 |

| CVE-2026-34605 | Cross-site scripting (XSS) in SiYuan personal knowledge management system versions 3.6.0-3.6.1 allows remote attackers to execute arbitrary JavaScript via the unauthenticated /api/icon/getDynamicIcon endpoint by bypassing SVG sanitization using XML namespace-prefixed element names. The vulnerability exploits a parser inconsistency where Go's HTML5 parser treats 'x:script' as a distinct tag while browsers' XML parsers resolve the namespace prefix to execute the script. Publicly available exploit code exists (GitHub issue #17246 documents the bypass technique), though no CISA KEV listing indicates mass exploitation campaigns at time of analysis. | HIGH | 8.6 | 0.0% | 63 |

| CVE-2026-23850 | Remote attackers can read arbitrary files from SiYuan servers (versions prior to 3.5.4) by exploiting server-side HTML rendering in the markdown feature. The path traversal vulnerability (CWE-22) requires no authentication and has low attack complexity, making it trivially exploitable. A public exploit exists and EPSS scoring indicates 9% exploitation probability (25th percentile), suggesting limited but active reconnaissance. Vendor patch available in version 3.5.4. | HIGH | 7.8 | 0.1% | 59 |
PoC
|
| CVE-2026-25992 | Unauthenticated attackers can read sensitive configuration files from SiYuan knowledge management systems prior to version 3.5.5 by exploiting case-sensitivity bypass in file access controls on Windows and other case-insensitive filesystems. The /api/file/getFile endpoint fails to properly validate mixed-case path traversal attempts, allowing unauthorized access to protected data. Public exploit code exists for this vulnerability, and no patch is currently available. | HIGH | 7.5 | 0.1% | 58 |
PoC
No patch
|
| CVE-2026-34453 | Unauthenticated information disclosure in SiYuan personal knowledge management system versions before 3.6.2 allows remote attackers to retrieve confidential content from password-protected documents via the publish service's bookmark API endpoint. The vulnerability bypasses document-level access controls by treating nil authentication contexts as authorized during bookmark filtering, exposing any bookmarked blocks without password verification. CVSS 7.5 (High) with network-based exploitation requiring no privileges or user interaction; no public exploit identified at time of analysis, though the security advisory provides detailed technical disclosure. | HIGH | 7.5 | 0.0% | 58 |
