EPSS

• CVE-2026-55500: 0.48% estimated exploitation activity in the next 30 days; percentile 41.46 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary 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 ALWAYSPROTECTED middleware check, which only validates JWT or CLI token. Combined with other vulnerabilities (e.g., default password, tunnel exposure), this enables complete database takeover. Description The endpoint /api/settings/database is listed in ALWAYSPROTECTED in dashboardGuard.js (line 42), which requires a valid JWT token or CLI token. However, this protection is insufficient because: 1. GET (Export): Returns the complete database including API keys (key field in apiKeys table), OAuth tokens, and all provider credentials. Line 80 in src/lib/db/index.js: apiKeys: db.all("SELECT FROM apiKeys").map(...) — the key field contains the plaintext API key value. 2. POST (Import): Accepts arbitrary JSON and performs a complete database wipe-and-replace…

# Patch Next advisory brief: CVE-2026-55500

Advisory: 9routers has Exposure of Sensitive Information and Unprotected Database Import/Export, Allowing Complete Credential Theft and Database Takeover
IDs: CVE-2026-55500, GHSA-qvfm-67h2-2qfx
Record: https://patchnext.com/advisories/cve-2026-55500 (revision 3, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm 9router: affected <= 0.4.71

## Suggested inspection (read-only)
- `npm ls 9router --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on 9router.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
