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.

The 12.2.1.4.0 and 14.1.1.0.0 versions of Coherence installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Centralized Thirdparty     Jars (jline)). Supported versions that are affected are 12.2.1.4.0 and 14.1.1.0.0. Easily exploitable     vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Coherence.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of Oracle Coherence. (CVE-2026-56740, CVE-2026-56741, CVE-2026-77420,     CVE-2026-77421, CVE-2026-77422)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
