GHSA-PM35-FQVH-CQ5G n8n: Legacy Expression Evaluator Sanitizer Bypass Leads to Authenticated Code Execution

Impact The legacy expression evaluator's computed-member sanitizer can be bypassed by an authenticated user with workflow create or modify permissions. Successful exploitation grants the attacker host-level code execution as the n8n process. The legacy expression engine is the default engine in...

GHSA-Q3J5-8VRG-4P9Q n8n: Shared Credential Header Leak via HTTP Request Pagination Expression

Impact An authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression. When an HTTP Header Auth credential is applied to a paginated request, the secret is present...

CVE-2026-13065

A user with read-only privileges is able to craft an aggregation pipeline using the $linearFill window function operator with a specific sortBy expression type to cause the mongod process to terminate abnormally, resulting in denial of service. The issue stems from insufficient validation of sort...

Server crash via aggregation pipeline expression with compound wildcard index specification

The $internalIndexKey aggregation expression can be used by any authenticated user to crash a MongoDB server mongod. The expression fails to handle compound wildcard index specifications, triggering an internal consistency check that aborts the server process. The user must be able to run an...

CVE-2026-9737

During query planning when reading the sort pattern in raw BSONObj form, in some places we don’t explicitly handle the meta expression case. This may lead to incorrect transformations leading to invariant failure...

CVE-2026-9737 Find command with $meta sort can lead to crash
