CWE-200Published: July 10, 2026· Updated: Jul 10, 2026

9.9

CVSS v3.1

Official Description

9Router is an AI router & token saver. Prior to 0.4.80, the /api/settings/database endpoint allows full database export (containing all credentials, API keys, OAuth tokens, and settings) and full database import (complete overwrite) without any authentication requirement beyond the ALWAYS_PROTECTED middleware check, which only validates JWT or CLI token. This issue is fixed in version 0.4.80.

Risk Analysis

This critical vulnerability in 9Router allows an unauthenticated attacker to export and import the entire database, including sensitive credentials and API keys. With a CVSS score of 9.9, this flaw presents an extreme risk for complete system compromise and data theft. The absence of an EPSS score means the likelihood of exploitation is not currently predictable, but the severity demands immediate attention.

No public exploit is currently known for this vulnerability. The attack vector is network-based with low complexity, indicating it is remotely exploitable.

Recommended Action

Upgrade 9Router to version 0.4.80 or later to fix this authentication bypass issue. Ensure all critical systems are properly authenticated and authorized.

Technical Analysis

CVE-2026-55500 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
