{"cve":"CVE-2026-93709","nvd":{"published":"2026-09-22T01:16:55.610","modified":"2026-09-23T20:17:23.067","status":"Deferred","description":"Dancer2 versions before 2.2.0 for Perl serve a layout as a page when an equivalent spelling of its path misses the guard in the AutoPage handler.\n\nThe handler compares the request path against the layout directory name as text, while the lookup that follows canonicalises it. A doubled slash, a dot segment, a percent-encoded slash, or a different capitalisation on a case-insensitive filesystem therefore misses the guard.\n\nThe handler is off by default, enabled with auto_page. The layout wrapping every page is already public, so this discloses one of the application's other layouts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-41"],"references":["https://github.com/PerlDancer/Dancer2/commit/293fce08812b0928f34ab2d7b9357450707c3630.patch","https://github.com/PerlDancer/Dancer2/commit/753b385350a54acb8d4b686723890205268634a8.patch","https://github.com/PerlDancer/Dancer2/issues/1823","https://metacpan.org/release/CROMEDOME/Dancer2-2.2.0/changes","http://www.openwall.com/lists/oss-security/2026/09/22/1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93709","score":0.00451,"percentile":0.39237,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
