Vulnerability from github – Published: 2026-07-17 03:31 – Updated: 2026-07-17 03:31
VLAI
Details

The Grav API plugin (getgrav/grav-plugin-api) before 1.0.0-rc.16 accepts JWT access tokens through the ?token= URL query parameter on every API route (JwtAuthenticator::extractBearerToken fallback). Because tokens are embedded in URLs, they are logged verbatim in web server access logs, leaked via the Referer header, stored in browser history, and captured by upstream proxy and CDN logs, exposing valid admin access tokens. A leaked token grants unauthorized API access, including reading configuration and user data, creating admin accounts, modifying system settings, and deleting pages.

Details

A flaw was found in the Quay config-tool's GitLab OAuth validator. This vulnerability causes sensitive credentials, specifically client_id and client_secret, to be transmitted as plaintext in URL query parameters during POST requests to the GitLab endpoint. This insecure transmission can lead to the disclosure of these credentials in various system logs, such as server access logs, reverse proxy logs, and other monitoring systems. An attacker with access to these logs could potentially obtain these credentials, leading to unauthorized information disclosure.

Summary
Auth0 Symfony SDK Accepted Bearer Tokens via URL Query Parameter
Details

Description

Applications built with the Auth0 Symphony SDK, using the Authorizer security authenticator to protect HTTP routes may accept OAuth 2.0 bearer access tokens provided through a URL query parameter, in addition to the standard Authorization header, which may increase the risk of access token exposure and replay against protected API endpoints.

Resolution

Upgrade auth0/symfony to version 5.9.0 or greater.

Acknowledgement

Okta would like to thank Alex Yeara for their discovery.

Details

Grav API plugin before v1.0.0-rc.16 accepts JWT tokens via the ?token= URL query parameter and responds with Access-Control-Allow-Origin: *, allowing unauthenticated attackers to make fully authenticated cross-origin API requests from any malicious website. Attackers who obtain a leaked JWT token from access logs, proxy logs, browser history, or Referrer headers can create persistent backdoor super-admin accounts and exfiltrate sensitive configuration and user data.

Summary
Nhost Leaks Refresh Tokens via URL Query Parameter in OAuth Provider Callback
Details

Refresh Token Leaked via URL Query Parameter in OAuth Provider Callback

Summary

The auth service's OAuth provider callback flow places the refresh token directly into the redirect URL as a query parameter. Refresh tokens in URLs are logged in browser history, server access logs, HTTP Referer headers, and proxy/CDN logs.

Note that the refresh token is one-time use and all of these leak vectors are on owned infrastructure or services integrated by the application developer.

Affected Component

  • Repository: github.com/nhost/nhost
  • Service: services/auth
  • File: services/auth/go/controller/sign_in_provider_callback_get.go
  • Function: signinProviderProviderCallback (lines 257-261)

Root Cause

In sign_in_provider_callback_get.go:257-261, after successful OAuth sign-in, the refresh token is appended as a URL query parameter:

if session != nil {
    values := redirectTo.Query()
    values.Add("refreshToken", session.RefreshToken)
    redirectTo.RawQuery = values.Encode()
}

This results in a redirect like:

HTTP/1.1 302 Found
Location: https://myapp.com/callback?refreshToken=a1b2c3d4-e5f6-7890-abcd-ef1234567890

Proof of Concept

Step 1: Initiate OAuth login

GET /signin/provider/github?redirectTo=https://myapp.com/callback

Step 2: Complete OAuth flow with provider

Step 3: Auth service redirects with token in URL

HTTP/1.1 302 Found
Location: https://myapp.com/callback?refreshToken=a1b2c3d4-e5f6-7890-abcd-ef1234567890

Step 4: Token is now visible in owned infrastructure and services:

Browser History:

# User's browser history now contains the refresh token

HTTP Referer Header:

# If the callback page loads ANY external resource (image, script, etc.):
GET /resource.js HTTP/1.1
Host: cdn.example.com
Referer: https://myapp.com/callback?refreshToken=a1b2c3d4-e5f6-...
# Note: modern browsers default to strict-origin-when-cross-origin policy,
# which strips query parameters from cross-origin Referer headers.
# Additionally, the Referer is only sent to services integrated by the
# application developer (analytics, CDNs, etc.), not arbitrary third parties.

Server Access Logs:

# Reverse proxy, CDN, or load balancer logs on owned infrastructure:
2026-03-08 12:00:00 GET /callback?refreshToken=a1b2c3d4-e5f6-... 200

Step 5: Attacker uses stolen refresh token

# Exchange stolen refresh token for new access token
curl -X POST https://auth.nhost.run/v1/token \
  -H 'Content-Type: application/json' \
  -d '{"refreshToken": "a1b2c3d4-e5f6-7890-abcd-ef1234567890"}'

# Note: refresh tokens are one-time use, so this only works if the
# legitimate client has not already consumed the token and if the attacker has
# compromised your infrastructure to get access to this information

Impact

  1. Session Hijacking: Anyone who obtains the token before it is consumed by the legitimate client can generate new access tokens, though the refresh token is one-time use and cannot be reused after consumption.

  2. Leak Vectors: URL query parameters are visible in owned infrastructure and integrated services:

  3. Browser history (local access)
  4. HTTP Referer headers (mitigated by modern browser default referrer policies; only sent to developer-integrated services)
  5. Server access logs (owned infrastructure)

  6. Proxy/CDN/WAF logs (owned infrastructure)

  7. Affects All OAuth Providers: Every OAuth provider flow (GitHub, Google, Apple, etc.) goes through the same callback handler.

Fix

Implemented PKCE (Proof Key for Code Exchange) for the OAuth flow. With PKCE, the authorization code cannot be exchanged without the code_verifier that only the original client possesses, preventing token misuse even if the URL is logged.

See: https://docs.nhost.io/products/auth/pkce/

Mitigation
Implementation

When sending sensitive information, only include it in the request body or request headers instead of the query string. This may require avoiding use of GET requests.

No CAPEC attack patterns related to this CWE.
