What is CVE-2026-80049?

The Airbyte Platform has a vulnerability that allows an attacker to bypass workspace authorization checks. This issue arises from the platform's dependency on the caller-supplied workspace ID without proper validation against the actual owning workspace. When handling requests, the system extracts information from the JSON body, which can lead to unauthorized access to resources. Consequently, any user can potentially manage (read, trigger, cancel, or delete) configuration for resources that belong to other workspaces, compromising data integrity and security. This highlights the need for robust permission checks and secure handling of user inputs within the platform.

Affected Version(s)

airbyte-platform 0 <= 2.0.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
