Apache Commons Text performs variable interpolation, allowing properties to
be dynamically evaluated and expanded. The standard format for
interpolation is “${prefix:name}”, where “prefix” is used to locate an
instance of org.apache.commons.text.lookup.StringLookup that performs the
interpolation. Starting with version 1.5 and continuing through 1.9, the
set of default Lookup instances included interpolators that could result in
arbitrary code execution or contact with remote servers. These lookups are:

  • “script” - execute expressions using the JVM script execution engine
    (javax.script) - “dns” - resolve dns records - “url” - load values from
    urls, including from remote servers Applications using the interpolation
    defaults in the affected versions may be vulnerable to remote code
    execution or unintentional contact with remote servers if untrusted
    configuration values are used. Users are recommended to upgrade to Apache
    Commons Text 1.10.0, which disables the problematic interpolators by
    default.
