# CVE-2024-56198: path-sanitizer allows bypassing the existing filters to achieve path-traversal vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.7% , percentile 54: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 54% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes path-sanitizer (npm) < 3.1.0, fixed in 3.1.0 . Check your lockfile, including transitive dependencies.

## What it is

path-sanitizer is a simple lightweight npm package for sanitizing paths to prevent Path Traversal. Prior to 3.1.0, the filters can be bypassed using .=%5c which results in a path traversal. This vulnerability is fixed in 3.1.0.

## Affected packages

- npm `path-sanitizer` < 3.1.0 → fixed: 3.1.0
