Is antlr-ng safe to use?

antlr-ng has a security risk score of 100/100 (CRITICAL risk). Our security analysis detected 353 findings. Review the detailed security assessment below to understand the specific risks before installation.

What are the security risks of antlr-ng?

Based on our automated security analysis, antlr-ng presents critical risk level. The extension is analyzed for malware patterns, secret exposure, network communications, permissions, and supply chain vulnerabilities.

How is the security score calculated?

Risky Plugins calculates security scores using weighted categories: severity of findings (25 points max), malware detections (35 points), secret exposure (28 points), network communications (10 points), and obfuscation (10 points). Scores range from 0-100, with higher scores indicating greater risk.

What does CRITICAL, HIGH, MEDIUM, LOW, MINIMAL risk mean?

CRITICAL (80-100): Severe security issues like malware. HIGH (60-79): Significant vulnerabilities. MEDIUM (40-59): Moderate security concerns. LOW (20-39): Minor issues. MINIMAL (0-19): Very low risk. Always review findings before installing any extension.
