Fix not verifiedVersions less than 0.1.4 of the static file server module fancy-server are vulnerable to directory traversal. An attacker can provide input such as `../` to read files outside of the served directory.
Versions less than 0.1.4 of the static file server module fancy-server are vulnerable to directory traversal. An attacker can provide input such as `../` to read files outside of the served directory.
Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
