What is CVE-2026-54313?

In the n8n workflow automation platform, prior to version 2.24.0, an input validation flaw allowed authenticated users with edit access to supply malicious input within the MongoDB node's Find And Replace operation. Due to the lack of validation, attacker-controlled query filters could be injected, leading to unintended data manipulation. This posed a significant risk as it could allow unauthorized access and modification of documents stored in MongoDB. This vulnerability was addressed in the 2.24.0 release.

Affected Version(s)
