CVE-2026-87811 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-13 7.3 High
SiYuan before v3.8.2 inserts persisted notebook template paths into HTML input value attributes without proper attribute encoding. Attackers can craft malicious template paths that break out of the attribute context and execute JavaScript when a victim opens notebook configuration, enabling same-origin API requests and application state manipulation.
CVE-2026-87807 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 7.5 High
siyuan versions before v3.8.2 contain an authenticated SQL injection vulnerability in the fullTextSearchBlock endpoint's method=1 query parameter. Attackers can inject UNION SELECT statements to read the entire blocks table, bypassing publish-access controls and exposing all document content and sensitive attributes.
CVE-2026-87808 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 4.9 Medium
SiYuan versions <= 3.8.1 contain an incomplete fix for CVE-2026-32767 (GHSA-j7wh-x834-p3r7). The prior fix (commit d5e2d0bc) added an administrator check for SQL mode (method=2) in POST /api/search/fullTextSearchBlock, but the endpoint still does not enforce the application's read-only boundary: for method=2 it forwards caller-supplied SQL to the blocks database query path without calling model.CheckReadonly or CheckReadonlyStatementInBox. As a result, when a workspace runs in read-only mode (--readonly=true), an authenticated administrator can submit arbitrary SQL through /api/search/fullTextSearchBlock and obtain raw read access to the blocks database, even though the dedicated /api/query/sql endpoint is blocked in that mode. Fixed in v3.8.2.
CVE-2026-87812 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 6.8 Medium
SiYuan before v3.8.2 contains a stored cross-site scripting vulnerability in Bazaar package cards where the iconURL metadata is inserted directly into HTML img src attributes without escaping. Attackers can inject malicious URLs with event handlers that execute JavaScript in the authenticated SiYuan origin when users view Bazaar listings, enabling API requests and application state manipulation.
CVE-2026-87813 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 7.3 High
SiYuan before v3.8.2 contains a stored cross-site scripting vulnerability in the Search Assets result list where asset filenames are interpolated into HTML without escaping. Authenticated attackers can craft asset filenames containing malicious markup that executes JavaScript in the victim's browser when searching assets, enabling same-origin API requests and application state manipulation.
CVE-2026-86192 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 6.5 Medium
SiYuan versions before v3.8.2 fail to properly filter private attribute-view cell values in the getAttributeViewKeys endpoint. Publish readers can retrieve hidden KeyValues payloads from rows bound to inaccessible documents, exposing private database contents without authorization.
CVE-2026-85581 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 7.5 High
SiYuan before v3.8.2 contains a denial of service vulnerability in the unauthenticated /api/system/uiproc endpoint that accepts and retains attacker-controlled process identifiers without size limits or authentication. Attackers can send repeated requests with unique identifiers to exhaust process memory and degrade service availability.
CVE-2026-86712 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 8.8 High
SiYuan before 3.8.2 trusts the attacker-writable text/siyuan clipboard MIME type and skips sanitization in the paste handler, allowing code execution in the Node-enabled desktop renderer. Attackers can craft malicious web pages that write to the clipboard, and when pasted into SiYuan, injected scripts execute with full Node.js access through the Electron main process.
CVE-2026-86191 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-08 4.3 Medium
SiYuan versions before v3.8.2 contain an information disclosure vulnerability in the getAttributeViewKeysByID endpoint that allows publish readers to enumerate private attribute view key definitions without verifying parent database visibility. Attackers can access the endpoint to retrieve complete key schemas including sensitive field names and relation definitions from hidden databases.
CVE-2026-85584 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-08 7.5 High
SiYuan versions before v3.8.2 contain a denial of service vulnerability in the publish-service Basic Auth throttle that stores failed-attempt state using attacker-controlled usernames without enforcing capacity limits or eviction policies. Unauthenticated attackers can submit repeated authentication requests with unique invalid usernames to exhaust memory and increase synchronization overhead, degrading service availability.
CVE-2026-85579 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-08 4.3 Medium
SiYuan is affected by an information disclosure vulnerability (confirmed in v3.8.1, fixed in v3.8.2) in the reader-accessible POST /api/transactions/undoState endpoint. The endpoint returns the peekMutatedRootIDs list from the global undo-log stack for a caller-supplied root ID without applying publish-access visibility filtering. An authenticated reader who knows the root ID of a visible document can obtain the internal root IDs of other documents (including private or unpublished ones) modified in the same cross-document transaction, disclosing internal identifiers and cross-document relationships. Document body contents are not directly exposed.
CVE-2026-85174 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-05 8.8 High
SiYuan before v3.8.2 logs API tokens from query parameters in plaintext to an accessible log file when full-text search requests exceed timing thresholds. Authenticated attackers can read the log file via the getFile endpoint to recover admin API tokens and gain permanent administrative access.
CVE-2026-85582 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-04 6.5 Medium
SiYuan versions before v3.8.2 contain an unbounded session creation vulnerability in the publish-service Basic Auth handler that allows authenticated attackers to exhaust memory. Attackers can repeatedly authenticate with valid credentials to create persistent session entries without expiry or capacity limits, causing indefinite process memory growth and denial of service.
CVE-2026-85585 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-04 7.5 High
SiYuan before v3.8.2 contains an unbounded resource consumption vulnerability in the request-concurrency middleware that retains mutex entries for every unique request path without eviction. Unauthenticated attackers can send numerous unique request paths to permanently increase process memory and synchronization overhead, degrading availability.
CVE-2026-85580 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-04 6.5 Medium
SiYuan versions before v3.8.2 contain a path guard bypass vulnerability in the MCP file-access handler that uses case-sensitive matching on Linux filesystems. Attackers can read the protected publishAccess.json file by requesting case-variant paths like PublishAccess.json to disclose sensitive publish-access configuration and metadata.
CVE-2026-85175 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-03 8.8 High
SiYuan versions <= 3.8.1 (fixed in v3.8.2) contain an incomplete blocklist in the IsForbiddenAbsPath() function (kernel/util/path_guard.go), which only blocks conf/conf.json by exact match and does not restrict the TLS private key (conf/key.pem) or CA private key (conf/ca.key) stored in the same conf/ directory. Because the getFile handler skips the blocklist for RoleAdministrator and all authenticated users receive RoleAdministrator in v3.8.1, any user (or any client on a default no-auth-code instance) can retrieve these private keys via POST /api/file/getFile. On deployments with TLS enabled, this allows decryption of captured HTTPS traffic (key.pem) and forging of certificates trusted by clients that imported SiYuan's CA (ca.key).
CVE-2026-84803 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-02 9 Critical
SiYuan before v3.8.2 contains a stored cross-site scripting vulnerability in asset serving due to an incomplete extension blocklist that misses script-capable file types. Attackers can upload files with extensions like .xht, .ehtml, .xsl, .xbl, or .rdf that resolve to executable media types and execute JavaScript to steal API tokens and compromise workspaces.
CVE-2026-82653 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-02 8.9 High
SiYuan before v3.8.1 contains a stored cross-site scripting vulnerability in confirmDialog() where unescaped package names and notebook names are interpolated directly into innerHTML assignments. Attackers can submit malicious bazaar packages with HTML/script payloads in the name field that execute in users' browsers when uninstalling packages or unlocking encrypted notebooks.
CVE-2026-82654 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-01 8.9 High
SiYuan before v3.8.1 fails to properly escape block name, alias, and memo fields in hint, backlink, and breadcrumb rendering functions. Attackers can set a block's name to contain HTML/script tags that execute when another user views documents referencing or displaying that block.
CVE-2026-82649 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-01 N/A
SiYuan Windows installer before version 3.8.1 (affected versions >= 2.0.14) contains an uncontrolled search path element vulnerability in its NSIS installer, which invokes system executables such as TASKKILL by name rather than by absolute path. Because NSIS nsExec::Exec resolves these calls using a search path that includes the installer's own launch directory ahead of System32, an attacker who plants a malicious executable (e.g., a renamed TASKKILL.exe) in that directory can have it executed when the installer runs. These calls occur in electron-builder's preInit hook before the license page is displayed, and with an all-users (elevated) install the planted binary executes with an elevated token, resulting in local privilege escalation.
