Mô tả
Impact
An attacker with write access to the git repository connected to an n8n Source Control configuration could commit a malicious Data Table JSON file containing a crafted column name. When an administrator performed a Source Control Pull, n8n imported the file and could lead to SQL injection on the internal PostgreSQL instance.
Exploitation requires all of the following conditions:
- The n8n instance uses PostgreSQL as its database backend.
- The Source Control feature is enabled and connected to a repository the attacker can write to.
- An administrator triggers a Source Control Pull.
Patches
The issue has been fixed in n8n version 1.123.43, 2.20.7, and 2.21.1. Users should upgrade to this version or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Disable the Source Control feature if it is not actively required.
- Restrict write access to the connected git repository to fully trusted users only.
- Avoid pulling from repositories that may have been modified by untrusted parties.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
Mô tả của NVD
n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an attacker with write access to the git repository connected to an n8n Source Control configuration could commit a malicious Data Table JSON file containing a crafted column name. When an administrator performed a Source Control Pull, n8n imported the file and could lead to SQL injection on the internal PostgreSQL instance. Exploitation requires the n8n instance uses PostgreSQL as its database backend, the Source Control feature is enabled and connected to a repository the attacker can write to, and an administrator triggers a Source Control Pull. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.
