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."}],"metrics":[{"cvssV3_1":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":7.5,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}]}],"problemTypes":[{"descriptions":[{"cweId":"CWE-24","description":"CWE-24 Path Traversal: '../filedir'","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","shortName":"mitre","dateUpdated":"2026-09-30T00:55:19.940Z"},"references":[{"url":"https://github.com/jknack/handlebars.java/security/advisories/GHSA-pvrx-3g7m-fpgv"},{"url":"https://github.com/jknack/handlebars.java/commit/f6ae3979917d05bef07f00befb4013ef00503660"},{"url":"https://github.com/jknack/handlebars.java/releases/tag/v4.5.5"}],"x_generator":{"engine":"CVE-Request-form 0.0.1"}},"adp":[{"references":[{"url":"https://github.com/jknack/handlebars.java/security/advisories/GHSA-pvrx-3g7m-fpgv","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-30T17:13:35.282546Z","id":"CVE-2026-103088","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-30T17:21:46.603Z"}}]}}
