    Regular Expression Denial of Service (ReDoS)

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) in reader/src/main/java/org/jline/reader/impl/history/DefaultHistory.java through matchPatterns() in the HISTORY_IGNORE history filter. An attacker can hang the reader thread and drive CPU usage high by supplying a crafted HISTORY_IGNORE value such as (a+)+b and then entering a non-matching command line that is checked against history. The vulnerable code converts the configuration string into a Java regex with only partial escaping, so regex metacharacters are interpreted by the matcher instead of being treated literally. Each time a command is added to history, the backtracking engine can spend exponential time evaluating the pattern, freezing interactive shells and any application embedding the JLine reader.

    How to fix Regular Expression Denial of Service (ReDoS)?

    Upgrade org.jline:jline-reader to version 3.30.15, 4.3.1 or higher.
