{"id":"CVE-2026-39847","summary":"Emmett has a path traversal in internal assets handler","details":"Emmett is a full-stack Python web framework designed with simplicity. From 2.5.0 to before 2.8.1, the RSGI static handler for Emmett's internal assets (/__emmett__ paths) is vulnerable to path traversal attacks. An attacker can use ../ sequences (eg /__emmett__/../rsgi/handlers.py) to read arbitrary files outside the assets directory. This vulnerability is fixed in 2.8.1.","aliases":["GHSA-pr46-2v3c-5356","PYSEC-2026-59"],"modified":"2026-07-15T01:48:53.848489749Z","published":"2026-04-07T21:37:54.760Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39847.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39847.json"},{"type":"ADVISORY","url":"https://github.com/emmett-framework/emmett/security/advisories/GHSA-pr46-2v3c-5356"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39847"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/emmett-framework/emmett","events":[{"introduced":"db19b6ee077b19afb223926fd2249d39ab74df35"},{"fixed":"bc367fe574bc9880636e4b0e831c8e588dc49c98"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:emmett:emmett:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.5.0"},{"fixed":"2.8.1"}]}}],"versions":["v2.8.0","v2.7.1","v2.7.0","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.13","v2.5.12","v2.5.11","v2.5.10","v2.5.9","v2.5.8","v2.5.7","v2.5.6","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.5.1","v2.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-39847.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
