Security readout for executives and security teams
Plain-English summary
Rocket League versions 1.95 and earlier reportedly install executable files with overly broad permissions. A logged-in user could change those files and potentially gain higher privileges on the Windows system. This is mainly a workstation risk, not a server-side Rocket League service issue.
Executive priority
Prioritize if Rocket League exists on managed corporate endpoints, labs, or shared workstations. The business impact is endpoint privilege escalation, which can help an insider or malware deepen compromise. If the software is absent, urgency is low.
Technical view
The issue is CWE-732 insecure permissions. Sources state the Authenticated Users group has Full Control over executable files, allowing modification by low-privileged authenticated users. CVSS is 8.8, but the described attack is privilege escalation through local file permissions. No vendor fix details are included in the provided sources.
Likely exposure
Organizations are exposed if they manage Windows endpoints with Rocket League version 1.95 or earlier installed, especially shared machines or systems where users lack administrative rights but can log in interactively.
Exploitation context
A Packet Storm entry is listed as an exploit reference, and third-party advisories are public. The source bundle does not show CISA KEV listing or confirmed active exploitation, so active exploitation should not be assumed.
Researcher notes
The CVSS vector lists network attack vector, but the description centers on authenticated modification of local executable files. Treat this as a post-authentication endpoint privilege-escalation issue unless vendor or advisory details prove remote reachability.
Mitigation direction
- Inventory endpoints for Rocket League installations and versions.
- Remove Rocket League where it is not business-approved.
- Update affected installations using official Epic/Rocket League distribution channels.
- Check vendor guidance for a fixed version or supported remediation.
- Restrict write access to game installation directories where operationally safe.
Validation and detection
- Identify systems running Rocket League version 1.95 or earlier.
- Review installation directory ACLs for Authenticated Users Full Control.
- Confirm non-admin users cannot modify installed executable files.
- Verify patched or current installations no longer expose unsafe permissions.
- Monitor endpoint controls for unexpected changes to game executables.

Incorrect Permission Assignment for Critical Resource
Incorrect Permission Assignment for Critical Resource represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
