Echo: org.jline:jline-builtins: security update to 3.30.15

high Tenable Cloud Security Plugin ID 473055

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - JLine is a Java library for handling console input. From 3.0.0 until 3.30.15 and 4.3.1, the JLine built-in
 grep command in builtins/src/main/java/org/jline/builtins/PosixCommands.java accepts a user-controlled
 regular expression in grep(...) and, unless line-regexp mode is used, automatically adds a dot-star prefix
 and suffix before compiling it with Java's backtracking regular expression engine. The wrapping expands
 the backtracking search space, so a short nested-quantifier expression evaluated against non-matching
 input can consume excessive CPU and indefinitely block a command worker, including in remotely exposed
 shell sessions. This issue is fixed in versions 3.30.15 and 4.3.1. (CVE-2026-77422)

Solution

Update the org.jline:jline-builtins library and its related packages to version 3.30.15 or later.
