{"id":"UBUNTU-CVE-2026-66755","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":"2026-09-03T16:06:44.486483644Z","published":"2026-07-30T20:18:00Z","related":["USN-8717-1"],"upstream":["CVE-2026-66755"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-66755"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-66755"},{"type":"REPORT","url":"https://lists.apache.org/thread/0hcctcp9s5lxgq2ookp4o6chltk99f8r"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8717-1"}],"affected":[{"package":{"name":"tika","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/tika?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.22-1ubuntu0.1~esm3"}]}],"versions":["1.22-1","1.22-1ubuntu0.1~esm1","1.22-1ubuntu0.1~esm2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"1.22-1ubuntu0.1~esm3","binary_name":"libtika-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-66755.json"}},{"package":{"name":"tika","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/tika?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.22-2+deb11u1ubuntu0.1~esm2"}]}],"versions":["1.22-2","1.22-2ubuntu0.22.04.1~esm1","1.22-2+deb11u1build0.22.04.1","1.22-2+deb11u1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtika-java","binary_version":"1.22-2+deb11u1ubuntu0.1~esm2"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-66755.json"}},{"package":{"name":"tika","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/tika?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.22-2","binary_name":"libtika-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-66755.json"}},{"package":{"name":"tika","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/tika?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22-2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.22-2","binary_name":"libtika-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
