CVE-2026-30848

Severity CVSS v4.0:
MEDIUM
Type:
CWE-22 Path Traversal
Publication date:
07/03/2026
Last modified:

Description

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.
