{"id":"CVE-2026-26032","summary":"Apache Ivy: PackagerResolver path traversal vulnerability","details":"The PackagerResolver of Apache Ivy is able to download online\nartifacts and to (re)package them in a format defined by a\npackager.xml file. This repackaging is done by an Ant script, which is\nstored in a subdirectory of the configured \"buildRoot\" directory. This\nsubdirectory is calculated based on modules coordinates, like the\norganisation, name or version.\n\nIf one of the coordinates contains \"../\" sequences - which are valid\ncharacters for Ivy coordinates in general- it is possible to break out\nof the configured \"buildRoot\" directory where other files can be\noverwritten.\n\nIn order to exploit this vulnerability an attacker needs to have\naccess to a packager repository and add or modify the coordinates in\nivy.xml files to have such \"../\" sequences.\n\nUsers of Apache Ivy 2.0.0 to 2.5.3 (inclusive) should upgrade to Ivy 2.6.0.","modified":"2026-07-17T03:46:04.668632814Z","published":"2026-07-15T18:49:43.153Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26032.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.0.0"},{"last_affected":"2.5.3"}]}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/15/5"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26032.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/4d9dzrlnoplvywnyj9x6w84kxg7n3jyq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26032"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/ant-ivy","events":[{"introduced":"d7c9277d38524c5c971a5ac3e2d23b7bc0d1221c"},{"fixed":"2927c79ff1c23964dfd00cb45182657c35b2e899"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.6.0"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:apache:ivy:*:*:*:*:*:*:*:*"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-26032.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
