Apache Commons Text versions 1.5 through 1.9 are susceptible to a vulnerability that, when successfully exploited, could lead to the disclosure of sensitive information, arbitrary code execution or contact with remote servers, addition or modification of data, or Denial of Service (DoS).
Apache Commons Text is a low-level library for performing various text operations, such as escaping, calculating string differences, and substituting placeholders in the text with values looked up through interpolators. Some of the available interpolators can trigger network access or code execution using the string substitution feature. This is intended, but it also means an application that includes user input in the string passed to the substitution without adequately sanitizing it would allow an attacker to trigger those interpolators.
Successful exploitation of this vulnerability could lead to the disclosure of sensitive information, addition or modification of data, or Denial of Service (DoS).
