Prior to 1.19.13, a path handling inconsistency in serveStatic allows protected static files to be accessed by using repeated slashes (//) in the request path. When route-based middleware (e.g., /admin/*) is used for authorization, the router may not match paths containing repeated slashes, while serveStatic resolves them as normalized paths. This can lead to a middleware bypass. This vulnerability is fixed in 1.19.13."}], "lastModified": "2026-04-21T18:38:40.410", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:hono:node-server:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "4615D37F-3481-4FE8-A893-9B3145848FBE", "versionEndIncluding": "1.19.12"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
