    + * The environment is defined by a set of variable definitions, which are + * name/value pairs of strings. Once this has been populated (via the + * {@link #defineVar(String, String)} and {@link #defineVars(Map)} methods), + * arbitrary strings can be expanded. + *

    + * + *

    + * Two modes of expansion are supported: + *

    + *
      + *
    • String mode ({@link #strExpand(String)}): The result is intended to be a + * single string.
    • + *
    • List mode ({@link #listExpand(String)}): The result will be interpreted + * as a command line, and hence is a list of strings. + *
    + * + *

    + * Variables are referenced by ${name} to trigger a string-mode + * expansion, and by ${=name} to trigger a list-mode expansion. + * This makes {@code $} a meta-character, and so it has to be escaped; the + * escape sequence for it is ${}. + *

    + * + *

    + * In list mode, strings are split in a platform-independent way similar (but + * not identical) to normal shell argument splitting. Runs of white-space + * separate arguments, and double-quotes can be used to protect whitespace from + * splitting. The escape character is backslash. All of these metacharacters + * have no special meaning in string mode. + *

    + * + *

    + * The {@code define*} and {@link #doNotExpand(String...)} methods of this + * class are not thread-safe; they mutate instance state in an unsynchronized + * way. By contrast, the expansion methods ({@link #strExpand(String)}, + * {@link #strExpandVar(String)}, {@link #listExpand(String)}, + * {@link #listExpandVar(String)} and {@link #varLookup(String)}) + * are thread safe relative to each + * other. This means that it's fine to construct an expansion environment once, + * and then use it from multiple threads concurrently, as long as no new variables + * are defined. In addition, {@link #validate(String)} is safe to call once an + * {@link ExpansionEnvironment} is fully initialised, even concurrently. + *

    + * + *

    + * Upon encountering any error (malformed variable expansion, malformed quoted + * string (in list mode), reference to unknown variable, cyclic variable + * definitions), the {@link #strExpand(String)} and {@link #listExpand(String)} + * methods will throw {@link UserError} with a suitable message. + *

    + * + *

    + * As an advanced feature, command substitutions can be supported. They take the + * form of $(cmd arg1 arg2) for string-mode expansion, and + * $(=cmd arg1 + * arg2) for list-mode. The contents of the $(..) operator + * undergo normal splitting, and are then run as a new process with the given + * list of arguments. The working directory is unspecified, and it is an error + * to depend upon it. A non-zero exit code, or a non-empty {@code stderr} stream + * of the command, will result in a {@link UserError} indicating that something + * went wrong; otherwise, the {@code stdout} output is collected and substituted + * (possibly undergoing splitting, in the second form). + *

    + JWT (JSON Web Token) is an open standard (RFC 7519) that defines a way to provide information + within a JSON object between two parties. JWT is widely used for sharing security information + between two parties in web applications. Each JWT contains encoded JSON objects, including a + set of claims. JWTs are signed using a cryptographic algorithm to ensure that the claims cannot + be altered after the token is issued. +

    +

    + The most basic mistake is using hardcoded secrets for JWT generation/verification. This allows + an attacker to forge the token if the source code (and JWT secret in it) is publicly exposed or + leaked, which leads to authentication bypass or privilege escalation. +

    +
    + + +

    + Generating a cryptographically secure secret key during application initialization and using this + generated key for JWT signing/verification requests can prevent this vulnerability. Or safely store + the secret key in a key vault that cannot be leaked in source code. +

    +
    + + +

    + The following examples show the bad case and the good case respectively. The bad + methods show a hardcoded secret key is used to sign and verify JWT tokens. In the good + method, the secret key is loaded from a system environment during application initialization. +
