{"schema":"threatline.record/2","record":{"id":"CVE-2026-118654","aliases":["GHSA-3pmx-cf9f-34xr"],"summary":"Echo static file middleware route protection bypass via encoded dot-dot traversal","details":"Echo is a Go web framework. Prior to 4.16.0 and 5.4.0, Echo's static file handlers can normalize dot segments after route matching and serve a file through a public static route even though the corresponding direct path is protected by route-level middleware. An unauthenticated attacker can read files that an application intended to protect with route-level middleware, when those files are also reachable through a static filesystem mount after path normalization. This vulnerability is the result of an incomplete fix for CVE-2026-55677. This issue is fixed in 4.16.0 and 5.4.0.","categories":["Unclassified"],"product":"echo","vendor":"labstack","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118654","source_modified_at":"2026-10-28T19:59:27.911Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":"echo","vendor":"labstack","versions":[{"version":"< 4.16.0","status":"affected"},{"version":">= 5.0.0, < 5.4.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T19:59:27.911Z","modified_at":"2026-10-28T19:59:27.911Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-118654","fetched_at":"2026-10-28T20:58:01.013507Z","source_modified_at":"2026-10-28T19:59:27.911Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/labstack/echo/security/advisories/GHSA-3pmx-cf9f-34xr","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/labstack/echo/commit/b838391e2eade87ae7e5a09d7bb5087bec271ec1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/labstack/echo/commit/fc410094b2f3415cf2bf5204082137b205bfd5af","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/labstack/echo/releases/tag/v4.16.0","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/labstack/echo/releases/tag/v5.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T19:59:27.911Z","content_hash":"bad00b493142a1a9b516aac8cf0790923fdb1445f5791e3536f6f451280f063b"}}
