# CVE-2025-8217: Inert Malicious script injected into Amazon Q Developer Visual Studio Code (VS Code) Extension

**Signal:** Normal patch cycle. No exploitation signal; fix it in your next routine update if you are affected. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.2% , percentile 12: FIRST’s model estimates a 0.2% chance of exploitation activity in the next 30 days, higher than 12% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
- Editorial verdict: Most can relax. Amazon Q VS Code Extension 1.84.0 Shipped a Wiper Prompt — A real supply-chain compromise with a payload that AWS says could not run; if nothing in your fleet still has 1.84.0, there is nothing left to do.

## What it is

The Amazon Q Developer Visual Studio Code (VS Code) extension v1.84.0 contains inert, injected code designed to call the Q Developer CLI. The code executes when the extension is launched within the VS Code environment; however the injected code contains a syntax error which prevents it from making a successful API call to the Q Developer CLI. To mitigate this issue, users should upgrade to version v1.85.0. All installations of v1.84.0 should be removed from use.

## Affected products (CVE record)

- Amazon Q Developer VS Code Extension: 1.84.0 < 1.85.0, sha256:47f7840ecab6312d2733e1274c513050405886c70f2037fb2f1e9099872b0464

## Severity

- AMZN CVSS 4.0: 5.1 `CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/U:Amber`
- AMZN CVSS 3.1: 4 `CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.22% probability of exploitation activity in the next 30 days; percentile 12.
