USN-8717-1: Apache Tika vulnerability

Publication date

3 September 2026

Overview

Apache Tika could be made to expose sensitive information over the network.


Packages

  • tika - A content analysis toolkit

Details

It was discovered that Apache Tika's ISA-Tab parser incorrectly handled
file path resolution. An attacker who could place files in a directory that
Tika subsequently parses could use this issue to read arbitrary files
accessible to the Tika process and have their contents emitted into the
extracted text output.
