# CVE-2025-71338: Flowise allows arbitrary file write to RCE

**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 1.2% , percentile 67: FIRST’s model estimates a 1.2% chance of exploitation activity in the next 30 days, higher than 67% 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 flowise (npm) <= 2.2.7, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Flowise through 2.2.7 fails to sanitize path segments in the document-store loader endpoint, allowing unauthenticated attackers to write files outside the storage directory. Attackers can use parent-directory sequences to escape the storage directory and overwrite application files loaded at boot for remote code execution.

## Affected packages

- npm `flowise` <= 2.2.7 → fixed: none listed

## Affected products (CVE record)

- Flowise Flowise: <= 2.2.7

## Severity

- VulnCheck CVSS 4.0: 10 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`
- VulnCheck CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 4.0: 10.0 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-11-05): 1.16% probability of exploitation activity in the next 30 days; percentile 67.
