Budibase versions before 3.41.3 contain a missing authorization vulnerability in the POST /api/resources/duplicate endpoint that allows authenticated builders to inject tables, automations, queries, and screens into any other application without holding any role in the destination workspace. Attackers can inject resources by specifying an arbitrary destination workspace ID in the request body, then trigger injected automations with outgoing webhooks to exfiltrate data from victim applications.

Budibase backend-core (@budibase/backend-core, as used by @budibase/server) omits the shared address space range 100.64.0.0/10 from its default SSRF blacklist (DEFAULT_BLACKLIST) used by REST datasource query previews. When the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Per the advisory, no released fix was identified at the time of publication; remediation is to add 100.64.0.0/10 to DEFAULT_BLACKLIST.

Budibase before 3.41.3 fails to validate app-scoped builder role assignments in the public user create and update endpoints, allowing an authenticated app-scoped builder to grant builder access to unrelated apps. Attackers can submit crafted requests to the user update API with builder.apps fields to escalate privileges and gain unauthorized builder access to other applications in the same tenant.

CVE ID :CVE-2026-82243 Published : Aug. 28, 2026, 12:16 p.m. | 1 hour, 52 minutes ago Description :Budibase Server before 3.41.3 contains a server-side request forgery vulnerability in the datasource verify endpoint that allows builder-level users to supply arbitrary URLs without SSRF validation. Attackers can exploit this to leak internal CouchDB credentials by making requests to attacker-controlled servers, gaining full database access in cloud deployments.

CVE ID :CVE-2026-82244 Published : Aug. 28, 2026, 12:16 p.m. | 1 hour, 52 minutes ago Description :Budibase versions before 3.41.3 contain a remote code execution vulnerability in plugin handling that allows authenticated admin users to execute arbitrary code by uploading a malicious plugin tarball. The server calls eval() on plugin JavaScript files without sandboxing in the main Node.js process, enabling attackers to exfiltrate environment variables and credentials with root privileges in default deployments.

Budibase before 3.41.3 fails to enforce per-table role restrictions on the POST /api/datasources/query endpoint, allowing low-privilege BASIC users to read, create, update, or delete rows in any table regardless of configured permissions. Attackers with BASIC role can submit crafted query requests with target table identifiers to bypass table-level access controls and manipulate restricted data.

SiYuan versions before v3.8.1 contain a server-side request forgery vulnerability in the http_request and web_fetch agent tools that perform DNS resolution only at guard time without validating the connect-time resolution. Attackers can use DNS rebinding to answer the guard resolution with a public IP and the connect resolution with a private or metadata IP, bypassing the SSRF defense to access cloud instance metadata and internal services.

CVE ID :CVE-2026-82237 Published : Aug. 28, 2026, 12:16 p.m. | 1 hour, 52 minutes ago Description :filebrowser through 2.63.23 does not remove share records when a shared file is renamed (only deletion triggers share cleanup). The share record is keyed by path, so it survives the rename and remains dormant (returning 404 while the path is empty). When any new, unrelated file later appears at the original shared path — via re-upload, another user with create permission, or a hook — the stale public share link serves that new file under the original link's password and expiry settings, unexpectedly exposing it.
