CVE-2024-55946 Overview
CVE-2024-55946 affects Playloom Engine, an open-source game development engine. The vulnerability exists in Engine Beta v0.0.1 and stems from insecure data storage when using the collaboration feature. Collaborating users can access personal information that other users entered into the software. The flaw maps to [CWE-200] Information Exposure. Maintainers have temporarily disabled the collaboration feature pending a fix. A patch is expected in Engine Beta v0.0.2.
Critical Impact
Remote attackers leveraging the collaboration feature can access personal information belonging to other users, breaching confidentiality without authentication or user interaction.
Affected Products
- Playloom Engine Beta v0.0.1
- Quetrobits Playloom Engine collaboration feature
- Earlier development builds exposing the collaboration workflow

Technical Details for CVE-2024-55946
Vulnerability Analysis
The vulnerability is an information exposure flaw in Playloom Engine Beta v0.0.1. When two or more users collaborate through the engine, personal data entered by one user becomes accessible to the other collaborator. The collaboration feature does not enforce proper data isolation between sessions. Sensitive fields are shared as part of the collaboration data stream rather than scoped per user. The EPSS score is 0.378% with a percentile of 29.651, indicating low observed exploitation interest. The maintainers disabled collaboration in the live product as a stop-gap control.
Root Cause
The root cause is insecure data storage within the collaboration subsystem. Personal user data is co-located with shared project state rather than being partitioned per identity. No access control check filters which fields a peer collaborator may retrieve. This design flaw allows trusted collaborators to read unrelated personal data that should remain local to the originating user.
Attack Vector
The attack vector is network-based and requires no privileges or user interaction beyond entering an existing collaboration session. An attacker invited to or joining a shared session receives the affected personal data as part of normal synchronization traffic. No memory corruption or code execution is involved. Refer to the GitHub Security Advisory for advisory-level technical details.
Detection Methods for CVE-2024-55946
Indicators of Compromise
- Use of Playloom Engine Beta v0.0.1 with the collaboration feature enabled in any project.
- Unexpected presence of another user's personal data fields within local project files or session caches.
- Network sessions to Playloom collaboration endpoints from hosts running the vulnerable beta build.
Detection Strategies
- Inventory developer workstations for Playloom Engine installations and flag any instance reporting version v0.0.1.
- Inspect application telemetry for activation of the collaboration feature after the maintainer's disable notice.
- Review collaboration session logs for personal data fields that should not have left the originating user's environment.
Monitoring Recommendations
- Monitor outbound traffic from developer endpoints to Playloom collaboration services and alert on usage of vulnerable versions.
- Track installation events and version strings for Playloom-Engine via endpoint software inventory.
- Audit shared project repositories for personal data artifacts originating from other accounts.
How to Mitigate CVE-2024-55946
Immediate Actions Required
- Stop using the collaboration feature in Playloom Engine Beta v0.0.1 immediately, in line with the maintainer guidance.
- Remove any personal or sensitive identifiers previously entered into Playloom projects that were shared through collaboration.
- Restrict Playloom Engine usage to isolated development hosts until a patched release is available.
Patch Information
No fixed release is available at publication time. The maintainers have temporarily disabled the collaboration feature and state that Engine Beta v0.0.2 is expected to contain a patch addressing this issue. Track the GitHub Security Advisory GHSA-75gm-rc5q-6jwv for release availability.
Workarounds
- Refrain from initiating or joining collaboration sessions in Playloom Engine until v0.0.2 is released.
- Use local-only project workflows and share artifacts through reviewed channels such as version control.
- Sanitize personal information from project metadata before any future collaboration session.
