{"id":"CVE-2026-66755","summary":"Apache Tika: Arbitrary Local File Read in ISArchiveParser","details":"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.","modified":"2026-09-03T03:30:25.545474140Z","published":"2026-07-30T19:16:42.370Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66755.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.8"},{"fixed":"3.3.2"},{"introduced":"4.0.0-alpha-1"},{"fixed":"4.0.0-beta-1"}]},{"extracted_events":[{"introduced":"1.8"},{"fixed":"3.3.1"}],"source":"DESCRIPTION"}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/30/23"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/66xxx/CVE-2026-66755.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/0hcctcp9s5lxgq2ookp4o6chltk99f8r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66755"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/tika","events":[{"introduced":"c57e805ee506123afc208eae5fd97fb4c4d1b8f7"},{"fixed":"b8a6916eab70ccdb5d4551c69be1a46af29c2cff"}],"database_specific":{"cpe":"cpe:2.3:a:apache:tika:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.8"},{"fixed":"3.3.2"}],"source":"CPE_RANGE"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-66755.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/AU:N"}]}
