Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1395: Dependency on Vulnerable Third-Party Component, where the product has a dependency on a third-party component that contains one or more known vulnerabilities. In Github.com/filebrowser/filebrowser/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The standard library `net/http` package dependency used by File Browser improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. I can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext. See https://nvd.nist.gov/vuln/detail/CVE-2025-22871 for more details.
