{"id":"CVE-2026-67185","summary":"TinyWeb 0.0.8 Path Traversal via URL Path Component","details":"TinyWeb through 0.0.8 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by submitting ../ sequences in the URL path, which are concatenated directly to the configured web root in HttpBuilder::buildResponse() without normalization, dot-segment removal, or boundary checks. Attackers can craft a single request with ../ sequences that pass through the URL parser unchanged and reach the filesystem call via HttpFile::setFile(), exposing sensitive files such as credential stores and private keys when the server process runs as root.","modified":"2026-10-08T02:51:37.983865639Z","published":"2026-07-28T16:30:45.229Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"0.0.8"},{"last_affected":"0.0.8"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67185.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67185.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67185"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/tinyweb-path-traversal-via-url-path-component"},{"type":"PACKAGE","url":"https://github.com/GeneralSandman/TinyWeb"},{"type":"EVIDENCE","url":"https://github.com/theopaid/Unauthenticated-Path-Traversal-Allows-Arbitrary-File-Read-TinyWeb-"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/GeneralSandman/TinyWeb","events":[{"introduced":"0b3b5fdb5a058f50248cd8547824936b8dd10351"},{"last_affected":"a381da252fe8e873c8aff22703040426cc9b2ae0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67185.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
