CVE-2026-114079 in trigger.dev
Summary
by MITRE • 10/22/2026
Trigger.dev before 4.5.6 contains an improper authorization vulnerability that allows holders of lower-trust environment API keys to cancel other environments' deployments because DeploymentService.getDeployment scopes lookups by projectId only. Attackers with a dev, preview, or CI secret key can POST to the deployment cancel endpoint to cancel in-progress production deployments within the same project.

Trigger.dev versions prior to 4.5.6 are affected by an improper authorization vulnerability that stems from insufficient scope validation during deployment management operations. The core technical flaw resides in the DeploymentService.getDeployment method, which performs access control checks based solely on the projectId associated with the API key and the target resource. This design oversight fails to verify whether the specific environment context of the requesting credential aligns with the environment of the deployment being accessed or modified. Consequently, the authorization logic treats all deployments within a given project as equally accessible regardless of their operational trust level, creating a significant gap in access control enforcement that undermines the intended isolation between different execution environments.
The practical impact of this vulnerability allows attackers possessing API keys designated for lower-trust environments to interfere with high-security operations. Specifically, individuals or automated systems holding development, preview, or continuous integration secret keys can successfully POST requests to the deployment cancellation endpoint targeting in-progress production deployments belonging to the same project ID. This capability enables unauthorized termination of critical production workloads, leading directly to service disruption and potential data inconsistency if those deployments were responsible for state-changing operations. The ability to cancel active production tasks effectively constitutes a denial-of-service condition against mission-critical infrastructure, as legitimate users are prevented from completing essential business processes due to external interference facilitated by weak credential scoping.
From an industry standard perspective, this vulnerability is classified under CWE-269: Improper Authorization, where the application does not properly restrict access to resources for unauthorized actors. The attack vector aligns with MITRE ATT&CK technique T1499: Endpoint Denial of Service, as the exploitation results in the disruption of normal system functionality by canceling active processes. Furthermore, it reflects CWE-862: Missing Authorization, indicating that the software does not perform an authorization check when a user attempts to access a resource or perform an action. The root cause is identified as CWE-732: Incorrect Permission Assignment for Critical Resource, where permissions are assigned incorrectly such that lower-privileged entities gain access to higher-privilege resources based on shared identifiers rather than strict environmental boundaries.
To mitigate this vulnerability, organizations must upgrade Trigger.dev to version 4.5.6 or later, which addresses the flawed scope lookup logic by enforcing stricter environment-level authorization checks alongside project ID validation. In the interim, administrators should implement network-level controls such as firewall rules or API gateways that restrict access to deployment management endpoints exclusively from trusted IP ranges associated with production environments. Additionally, adopting a principle of least privilege involves segregating API keys more rigorously and ensuring that CI/CD pipelines do not utilize credentials capable of interacting with production resources unless absolutely necessary through isolated service accounts with minimal permissions. Regular auditing of API key usage patterns can also help detect anomalous cancellation attempts originating from non-production environments before they cause significant operational damage.
