CVE-2025-62726
ADVISORY - githubSummary
Impact
A remote code execution vulnerability exists in the Git Node component available in both Cloud and Self-Hosted versions of n8n. When a malicious actor clones a remote repository containing a pre-commit hook, the subsequent use of the Commit operation in the Git Node can inadvertently trigger the hook’s execution.
This allows attackers to execute arbitrary code within the n8n environment, potentially compromising the system and any connected credentials or workflows.
All users with workflows that utilize the Git Node to clone untrusted repositories are affected.
Patches
The vulnerability was addressed in v1.113.0 (n8n-io/n8n#19559), which introduces a new environment variable: N8N_GIT_NODE_DISABLE_BARE_REPOS. For self-hosted deployments, it is strongly recommended to set this variable to true to mitigate the risk of executing malicious Git hooks.
Workarounds
To reduce risk prior to upgrading:
- Avoid cloning or interacting with untrusted repositories using the Git Node.
- Disable or restrict the use of the Git Node in workflows where repository content cannot be fully trusted.

CVSS:3 Severity and metrics
The CVSS metrics represent different qualitative aspects of a vulnerability that impact the overall score, as defined by the CVSS Specification.
The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery (IPv6) flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014).
Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.
The attacker requires privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
The vulnerable system can be exploited without interaction from any user.
An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
There is a total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any or all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component.
