{"id":"CVE-2026-103088","details":"Handlebars.java before 4.5.5 allows directory traversal. In handlebars-springmvc 4.5.3 and 4.5.4, the path-containment fix for CVE-2026-63490 validates template locations as raw percent-encoded strings, whereas the template file is opened through a URL handler that percent-decodes the path. In a Spring MVC application with a file: template prefix and a request-derived view name, a percent-encoded traversal such as %2e%2e/ bypasses both the view-resolver check and the loader-side containment and reads files outside the configured template base directory.","aliases":["GHSA-pvrx-3g7m-fpgv"],"modified":"2026-10-02T03:31:11.568787321Z","published":"2026-09-30T00:55:19.940Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-24"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103088.json"},"references":[{"type":"WEB","url":"https://github.com/jknack/handlebars.java/releases/tag/v4.5.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103088.json"},{"type":"ADVISORY","url":"https://github.com/jknack/handlebars.java/security/advisories/GHSA-pvrx-3g7m-fpgv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103088"},{"type":"FIX","url":"https://github.com/jknack/handlebars.java/commit/f6ae3979917d05bef07f00befb4013ef00503660"},{"type":"PACKAGE","url":"https://github.com/jknack/handlebars.java"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jknack/handlebars.java","events":[{"introduced":"a733ae1e2b3b24d3857bd4cfff080130d777bdc7"},{"fixed":"f6ae3979917d05bef07f00befb4013ef00503660"}],"database_specific":{"extracted_events":[{"introduced":"4.5.3"},{"fixed":"4.5.5"},{"introduced":"Handlebars.java"}],"source":["AFFECTED_FIELD","DESCRIPTION","REFERENCES"]}}],"versions":["v4.5.4","v4.5.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-103088.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
