Detect Remotion RCE via Code Injection (CVE-2026-30120) in IBM QRadar
Detects exploitation of CVE-2026-30120, a critical remote code execution vulnerability in the Remotion npm package (versions < 4.0.410). The vulnerability stems from improper code injection controls (CWE-94), allowing attackers to execute arbitrary code in environments running vulnerable Remotion versions. A public PoC exists, elevating exploitation risk.

Testing Methodology
Validate this detection against 3 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Simulate Remotion Code Injection via eval()
Expected signal: Process launch event for node with command line containing 'remotion' and 'eval('. Child process event for 'id' command spawned from node. File creation event for /tmp/cve_2026_30120_test.txt.
- Test 2Simulate Remotion execSync Child Process Spawn
Expected signal: Process event for node with title 'remotion-renderer'. child_process module load. Execution of 'whoami'. File write to /tmp/remotion_rce_test.txt.
- Test 3Simulate Remotion RCE on Windows via spawnSync
Expected signal: DeviceProcessEvents entry for node.exe with 'remotion' and 'spawnSync' in CommandLine. Child process event for cmd.exe spawned from node.exe. File write event for remotion_rce_test.txt in TEMP directory.
