{"id":"CVE-2026-30848","summary":"Parse Server: `PagesRouter` path traversal allows reading files outside configured pages directory","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.8 and 9.5.0-alpha.8, the PagesRouter static file serving route is vulnerable to a path traversal attack that allows unauthenticated reading of files outside the configured pagesPath directory. The boundary check uses a string prefix comparison without enforcing a directory separator boundary. An attacker can use path traversal sequences to access files in sibling directories whose names share the same prefix as the pages directory (e.g. pages-secret starts with pages). This issue has been patched in versions 8.6.8 and 9.5.0-alpha.8.","aliases":["BIT-parse-2026-30848","GHSA-hm3f-q6rw-m6wh"],"modified":"2026-04-10T05:41:55.040359Z","published":"2026-03-07T16:20:22.220Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30848.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30848.json"},{"type":"ADVISORY","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-hm3f-q6rw-m6wh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30848"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/parse-community/parse-server","events":[{"introduced":"532a461d30a6ed4457839f2caf5f30d5abf51a55"},{"fixed":"01267ae5ae4bacae630195f287b64f213f23c07a"}]}],"versions":["9.0.0","9.1.0","9.1.1","9.2.0","9.3.0","9.3.1","9.4.0","9.4.1","9.5.0-alpha.1","9.5.0-alpha.2","9.5.0-alpha.3","9.5.0-alpha.4","9.5.0-alpha.5","9.5.0-alpha.6","9.5.0-alpha.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30848.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
