CVE-2026-66723: CWE-862: Missing Authorization in CERT.PL MWDB Core
MWDB Core versions >=2.2.0 and <2.19.0 contain a missing authorization vulnerability in the Remote Instances proxy API. The proxy API does not verify authentication for incoming requests, allowing an unauthenticated remote attacker to send arbitrary requests to a remote MWDB instance using the identity and permissions associated with the configured API key. This can result in unauthorized actions being performed on the remote instance as if executed by the user whose API key was used to set up the remote instance. The vulnerability is limited to deployments where Remote Instances have been configured.This issue has been fixed in version 2.19.0
AI Analysis
Technical Summary
CVE-2026-66723 is a missing authorization vulnerability (CWE-862) in CERT.PL's MWDB Core product affecting versions >=2.2.0 and <2.19.0. The Remote Instances proxy API does not verify authentication for incoming requests, enabling unauthenticated remote attackers to perform unauthorized actions on a remote MWDB instance by leveraging the identity and permissions of the API key used to configure that instance. This can lead to unauthorized operations being executed as if by the legitimate user. The vulnerability is limited to deployments with Remote Instances configured and has been fixed in version 2.19.0.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to send arbitrary requests to a remote MWDB instance, effectively performing unauthorized actions with the privileges of the configured API key. This can compromise the integrity and security of the remote instance by allowing actions that should require authentication and authorization.
Mitigation Recommendations
Upgrade MWDB Core to version 2.19.0 or later, where this vulnerability has been fixed. There is no indication of an official temporary fix or workaround, so applying the official patch is the recommended remediation.
