Dream Displays: Command-line argument injection in yt-dlp invocation
Summary
Dream Displays, a Minecraft mod for in-game video screens, passes user-controlled input to the yt-dlp tool in affected versions. An attacker who can influence this input can inject unintended command-line options that change how yt-dlp behaves. The trigger conditions are not documented in the available sources, and the more severe impacts reported by third-party databases could not be verified.
Affected
- Dream Displays versions 1.5.0 up to but excluding 1.8.2
Fixed in
- Version 1.8.2 (confirmed fix)
- Later releases such as 1.10.x are not confirmed as fixes in the sources; use the latest release from the vendor
Workaround
- Unknown. No vendor-published workaround was found.
- Removing the mod from untrusted or unmanaged systems is the more reliable interim step.
Exploitation
- No confirmed exploitation in the wild. CISA SSVC: exploitation none, automatable yes, technical impact partial.
- No public proof of concept found.
Our recommendation
- Inventory all Minecraft clients and servers running Dream Displays, including the jar version.
- Upgrade to the latest release, at minimum 1.8.2.
- Remove the mod from workstations and unmanaged servers where it is not business-critical.
- Check the GHSA advisory for the official impact and trigger conditions.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
Dream Displays provides in-game screens for streaming videos in Minecraft. From 1.5.0 until 1.8.2, user-controlled input can influence arguments passed to `yt-dlp` under specific conditions. Unintended command-line options may be interpreted by `yt-dlp`, potentially altering its behavior. This issue is fixed in version 1.8.2.
