Arbitrary OS command injection vulnerabilities are more likely when a shell is spawned rather than a new process, indeed shell meta-chars can be used (when parameters are user-controlled for instance) to inject OS commands. For more information checkout the CWE-78 (https://cwe.mitre.org/data/definitions/78.html) advisory.

Command line arguments can be dangerous just like any other user input. They should never be used without being first validated and sanitized. Remember also that any user can retrieve the list of processes running on a system, which makes the arguments provided to them visible. Thus passing sensitive information via command line arguments should be considered as insecure. This rule raises an issue when on every program entry points (main methods) when command line arguments are used. The goal is to guide security code reviews. Sanitize all command line arguments before using them. For more information checkout the CWE-88 (https://cwe.mitre.org/data/definitions/88.html) advisory.

When software generates predictable values in a context requiring unpredictability, it may be possible for an attacker to guess the next value that will be generated, and use this guess to impersonate another user or access sensitive information. As the Math.random() function relies on a weak pseudorandom number generator, this function should not be used for security-critical applications or for protecting sensitive data. In such context, a cryptographically strong pseudorandom number generator (CSPRNG) should be used instead. For more information checkout the CWE-338 (https://cwe.mitre.org/data/definitions/338.html) advisory.

To perform secure cryptography, operation modes and padding scheme are essentials and should be used correctly according to the encryption algorithm:For block cipher encryption algorithms (like AES), the GCM (Galois Counter Mode) mode that works internally with zero/no padding scheme, is recommended. At the opposite, these modes and/or schemes are highly discouraged:Electronic Codebook (ECB) mode is vulnerable because it doesn't provide serious message confidentiality: under a given key any given plaintext block always gets encrypted to the same ciphertext block.Cipher Block Chaining (CBC) with PKCS#5 padding (or PKCS#7) is vulnerable to padding oracle attacks.RSA encryption algorithm should be used with the recommended padding scheme (OAEP). More specifically for block cipher, it's not recommended to use algorithm with a block size inferior than 128 bits. For more information checkout the CWE-327 (https://cwe.mitre.org/data/definitions/327.html) advisory.

The debugger statement can be placed anywhere in procedures to suspend execution. Using the debugger statement is similar to setting a breakpoint in the code. By definition such statement must absolutely be removed from the source code to prevent any unexpected behavior or added vulnerability to attacks in production. For more information checkout the CWE-489 (https://cwe.mitre.org/data/definitions/489.html) advisory.
