CVE-2026-66755 Details
Description
Relative Path Traversal in the ISA-Tab parser in Apache Software Foundation Apache Tika from 1.8 through 3.3.1, and 4.0.0-alpha-1, allows an attacker who can place files in a directory that the application subsequently parses to read arbitrary files accessible to the Tika process and have their contents emitted into the extracted text output, via a "Study Assay File Name" value in the ISA-Tab investigation file that traverses outside the dataset directory. Users are recommended to upgrade to version 3.3.2 or 4.0.0-beta-1, which fixes this issue.
A relative path traversal vulnerability has been identified in the ISA-Tab parser of Apache Tika. This issue affects versions 1.8 prior to 3.3.1 and 4.0.0-alpha-1, allowing an attacker to read arbitrary files accessible to the Tika process. The vulnerability arises when files are placed in a directory that Tika subsequently parses. Exploitation involves using a 'Study Assay File Name' value in the ISA-Tab investigation file that traverses outside the dataset directory, leading to the contents of the accessed files being emitted into the extracted text output.
Users are advised to upgrade to Apache Tika version 3.3.2 or 4.0.0-beta-1, both of which address this vulnerability.
