CVE-2026-24809
📋 TL;DR
A heap-buffer overflow vulnerability in the luaG_runerror function in praydog/REFramework allows attackers to execute arbitrary code or cause denial of service when a recursive error occurs. This affects users of REFramework versions before 1.5.5 who process untrusted Lua scripts. The vulnerability stems from improper bounds checking during error handling.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crash or denial of service, potentially allowing privilege escalation if the framework runs with elevated permissions.
If Mitigated
Contained application crash without system compromise if proper sandboxing and memory protections are enabled.
🎯 Exploit Status
Exploitation requires crafting malicious Lua scripts that trigger recursive errors. No public exploits have been reported as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.5.5
Vendor Advisory: https://github.com/praydog/REFramework/pull/1320
Restart Required: Yes
Instructions:
1. Download REFramework version 1.5.5 or later from GitHub. 2. Replace existing REFramework files with the updated version. 3. Restart any applications using REFramework.
🔧 Temporary Workarounds
Disable Lua Script Processing
allPrevent REFramework from executing Lua scripts to eliminate attack surface.
Modify REFramework configuration to disable Lua support
🧯 If You Can't Patch
- Restrict REFramework to trusted Lua scripts only from verified sources.
- Run REFramework in a sandboxed environment with limited permissions.
🔍 How to Verify
Check if Vulnerable:
Check REFramework version in application settings or about dialog. Versions below 1.5.5 are vulnerable.Check Version:
Check REFramework UI or configuration files for version information.Verify Fix Applied:
Confirm version is 1.5.5 or higher and test with known problematic Lua scripts if available.📡 Detection & Monitoring
