GHSA-JVC7-762P-3743
Vulnerability from github – Published: 2026-06-16 19:00 – Updated: 2026-06-16 19:00Impact
The MicrosoftAgent365Trigger and StripeTrigger node did not validate that inbound requests. As a result, an unauthenticated attacker who knows the webhook URL could submit a forged payload and cause the workflow to execute with attacker-controlled data.
Patches
The issue has been fixed in n8n versions 2.25.7, and 2.26.2. Users should upgrade to one of these versions or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Deactivate any workflows using the Microsoft Agent 365 Trigger node or Stripe Trigger node until the instance can be upgraded. - Restrict network access to the n8n webhook endpoint to trusted sources only.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

It uses MAC address verification as the sole mechanism for recognizing paired devices, allowing attackers to bypass authentication. By capturing the MAC address of an already-paired device through ARP scanning or other means, an attacker can spoof the MAC address and connect to the dashcam without going through the pairing process.

No mitigation information available for this CWE.
CAPEC-21: Exploitation of Trusted Identifiers
An adversary guesses, obtains, or "rides" a trusted identifier (e.g. session ID, resource ID, cookie, etc.) to perform authorized actions under the guise of an authenticated user or service.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-461: Web Services API Signature Forgery Leveraging Hash Function Extension Weakness
An adversary utilizes a hash function extension/padding weakness, to modify the parameters passed to the web service requesting authentication by generating their own call in order to generate a legitimate signature hash (as described in the notes), without knowledge of the secret token sometimes provided by the web service.
CAPEC-473: Signature Spoof
An attacker generates a message or datablock that causes the recipient to believe that the message or datablock was generated and cryptographically signed by an authoritative or reputable source, misleading a victim or victim operating system into performing malicious actions.
CAPEC-476: Signature Spoofing by Misrepresentation
An attacker exploits a weakness in the parsing or display code of the recipient software to generate a data blob containing a supposedly valid signature, but the signer's identity is falsely represented, which can lead to the attacker manipulating the recipient software or its victim user to perform compromising actions.
CAPEC-59: Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
CAPEC-60: Reusing Session IDs (aka Session Replay)
This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
CAPEC-667: Bluetooth Impersonation AttackS (BIAS)
An adversary disguises the MAC address of their Bluetooth enabled device to one for which there exists an active and trusted connection and authenticates successfully. The adversary can then perform malicious actions on the target Bluetooth device depending on the target’s capabilities.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
