Title
n8n before 2.39.6 and 2.40.x before 2.40.1 Filter Bypass via Parameter Interpolation
Summary
n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an unescaped parameter interpolation vulnerability in SendGrid, Freshservice, and ServiceNow nodes that allows attackers to bypass filters by breaking out of query literals. Attackers can exploit this by binding vulnerable node parameters to untrusted external input to widen single-record lookups into match-all queries, exposing bulk data including contact lists, tickets, and directory entries.

Title
Parse Server 9.0.0 Unauthenticated Installation Deletion via Operator Injection
Summary
Parse Server is an open source backend server. In versions prior to 8.6.90 and in versions from 9.0.0 prior to 9.10.1-alpha.9, the device token deduplication logic for installation records does not validate the type of client-supplied installation fields before using them to build database queries. An unauthenticated remote attacker who knows only the public application ID can submit non-string values in these fields to inject query operators, causing the deduplication cleanup — which runs with elevated privileges before class-level permissions are evaluated — to delete every device registration in the application or an attacker-chosen subset of them. No account, session token, master key, or user interaction is required. Deleted registrations cannot be recovered on the server, so push notifications cannot be delivered until every client re-registers. Any deployment that exposes the REST API to clients and uses push notifications is affected in its default configuration. Versions 8.6.90 and 9.10.1-alpha.9 fix the issue by rejecting non-string values with a client error and by scoping the deduplication cleanup to the calling application. No workaround other than upgrading is available.

"value": "Parse Server is an open source backend server. In versions prior to 8.6.90 and in versions from 9.0.0 prior to 9.10.1-alpha.9, the device token deduplication logic for installation records does not validate the type of client-supplied installation fields before using them to build database queries. An unauthenticated remote attacker who knows only the public application ID can submit non-string values in these fields to inject query operators, causing the deduplication cleanup \u2014 which runs with elevated privileges before class-level permissions are evaluated \u2014 to delete every device registration in the application or an attacker-chosen subset of them. No account, session token, master key, or user interaction is required. Deleted registrations cannot be recovered on the server, so push notifications cannot be delivered until every client re-registers. Any deployment that exposes the REST API to clients and uses push notifications is affected in its default configuration. Versions 8.6.90 and 9.10.1-alpha.9 fix the issue by rejecting non-string values with a client error and by scoping the deduplication cleanup to the calling application. No workaround other than upgrading is available."

Title
Rapid7 Bulk Export MCP — GraphQL Query Injection in Export Status Lookup
Summary
Rapid7 Bulk Export MCP versions 0.2.5 through 0.6.1 suffer from a GraphQL query injection issue in the export-status component (`get_export_status` in `src/export_manager.py`), whereby the `export_id` value — an unvalidated MCP tool argument reaching the function via the `check_rapid7_export_status` and `download_rapid7_export` tools — is interpolated directly into the GraphQL query string. A crafted `export_id` containing quote and brace characters can terminate the intended `export(id: "...")` selection early and append attacker-controlled root-level selections (for example, schema introspection), producing a single well-formed GraphQL document that is then sent to the Rapid7 export API under the operator's own API key.
Notably, this issue does not grant an existing actor any access they do not already have: every injected query executes within the operator's own already-authenticated API scope, using the operator's own valid API key, and cannot cross a tenant or account boundary. A directly-malicious operator gains nothing they could not already do by calling the API directly; the realistic exposure is limited to a compromised or careless upstream MCP client, or indirect prompt injection forwarding an unvalidated identifier. This is fixed in version 0.6.2, which passes `export_id` as a parameterized GraphQL variable (`$exportId: ID!`).

Title
Unauthorized cache lock takeover via expression injection in lock owner values in MongoDB integration for Laravel
Summary
Improper neutralization of special elements in data query logic in the cache lock implementation of the MongoDB integration for Laravel can cause a caller-supplied lock owner value to be evaluated as an aggregation expression rather than as a literal value. An authenticated user who can influence the owner value an application uses when acquiring or restoring a lock may take over or prematurely expire a lock held by another process, which can lead to duplicated or conflicting operations.

Title
NoSQL injection of JavaScript-executing query operators via unsafe-by-default operator guard
Summary
Mongoid does not restrict which query operators may come from caller-supplied filter data when an application hands that data to its query-building methods. In an application that forwards externally supplied filter parameters in this way, a party with no credentials may influence how the database evaluates the query. This may result in unintended disclosure of stored field values and in reduced database performance.

Title
Flowise before 3.1.4 NoSQL Injection via sessionId
Summary
Flowise before 3.1.4 fails to sanitize the overrideConfig.sessionId parameter before using it in MongoDB queries within the MongoDBMemory node. Unauthenticated attackers can submit MongoDB operator objects through the prediction API to read chat history records belonging to other users from the shared collection.

Title
Discourse: Escape LIKE metacharacters in upload paths to prevent disclosure
Summary
Discourse is an open-source discussion platform. Prior to 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0, authenticated users could supply unescaped SQL LIKE metacharacters to upload-resolution patterns, causing wildcard input to select unrelated upload records instead of matching a literal identifier. The affected upload metadata, URL-lookup, and cooked-video-placeholder paths could resolve uploads the user was not authorized to access. This allowed disclosure of restricted metadata, including original filenames and secure-upload paths, without modifying the upload records. This issue is fixed in versions 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0.

Title
GridFS data disclosure and deletion via query-operator injection in file IDs in the MongoDB C Driver
Summary
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.

CAPEC-676: NoSQL Injection
An adversary targets software that constructs NoSQL statements based on user input or with parameters vulnerable to operator replacement in order to achieve a variety of technical impacts such as escalating privileges, bypassing authentication, and/or executing code.
