Vulnerability from github – Published: 2026-05-18 17:55 – Updated: 2026-05-18 17:55Mistral npm @mistralai/mistralai, @mistralai/mistralai-azure, @mistralai/mistralai-gcp were compromised by a supply chain attack related to the TanStack security incident. An automated worm associated with the attack led to compromised npm package versions being published.
Current investigation indicates that an affected developer device was involved. We have no indication that Mistral infrastructure was compromised. The compromised versions were removed from npm. They were available only between May 11 at 22\:45 UTC and May 12 at 01\:53 UTC. Previous and later versions are not affected by this advisory.
Impact
The dropper is broken, it has no impact.
- setup.mjs references tanstack_runner.js but the payload file is named router_init.js
- execFileSync throws ENOENT and the tmpdir is wiped before payload runs. Bun gets downloaded to a tmpdir but no payload execution.
We still recommend removing the packages, see below for remediation.
Check whether you are affected
You are affected if one of the package versions above was installed in any environment during the exposure window or is present in a lockfile, build artifact, container image, package cache, or deployment image.
| Package | Affected versions |
|---|---|
@mistralai/mistralai |
2.2.2, 2.2.3, 2.2.4 |
@mistralai/mistralai-azure |
1.7.1, 1.7.2, 1.7.3 |
@mistralai/mistralai-gcp |
1.7.1, 1.7.2, 1.7.3 |
Check installed versions:
npm ls @mistralai/mistralai @mistralai/mistralai-azure @mistralai/mistralai-gcp
grep -n -A 4 -B 2 -E '@mistralai/(mistralai|mistralai-azure|mistralai-gcp)|2\.2\.[2-4]|1\.7\.[1-3]' \
package-lock.json pnpm-lock.yaml yarn.lock 2>/dev/null
Look for any of the following files
- router_init.js (embedded in all @tanstack packages): ab4fcadaec49c03278063dd269ea5eef82d24f2124a8e15d7b90f2fa8601266c
- tanstack_runner.js (from git commit): 2ec78d556d696e208927cc503d48e4b5eb56b31abc2870c2ed2e98d6be27fc96
- @tanstack/setup package.json: 7c12d8614c624c70d6dd6fc2ee289332474abaa38f70ebe2cdef064923ca3a9b
You may also run this (read-only) script that will automatically flag known malicious files.
You are not affected by this advisory if you did not install the affected package versions and they are not present in your lockfiles, build caches, deployment artifacts, or package mirrors.
If the command finds an affected version, continue with the remediation steps below. If you use private package mirrors, caches, or container base images, check those copies too.
Remediate affected systems
- Stop using the affected package version immediately.
- Clean systems where one of this package has been installed.

Vulnerability from github – Published: 2018-07-23 20:54 – Updated: 2023-09-13 21:43The jquery.js package is a piece of malware that steals environment variables and sends them to attacker controlled locations.
All versions have been unpublished from the npm registry.
Recommendation
As this package is malware, if you find it installed in your environment, the real security concern is determining how it got there.
If you have found this installed in your environment, you should: 1. Delete the package 2. Clear your npm cache 3. Ensure it is not present in any other package.json files on your system 4. Regenerate your registry credentials, tokens, and any other sensitive credentials that may have been present in your environment variables.
Additionally, any service which may have been exposed via credentials in your environment variables, such as a database, should be reviewed for indicators of compromise as well.

Recommendation
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Vulnerability from github – Published: 2026-06-04 19:37 – Updated: 2026-06-04 19:37Impact
On May 19, 2026, a compromised version of @cap-js/openapi@1.4.1 was published. The malicious packages harvested credentials and attempted self-propagation. If a compromised version was installed, all credentials accessible on that machine (npm tokens, cloud provider credentials, SSH keys, GitHub PATs) should be considered compromised.
Patches
Upgrade to @cap-js/openapi >= 1.4.2 If the compromised version was ever installed, rotate all affected credentials.
Workarounds
No workarounds.

Vulnerability from github – Published: 2026-08-21 03:31 – Updated: 2026-08-21 03:31The arrayref crate 0.3.10 for Rust can trigger execution of malicious code when compiling a project that uses the crate, because it has a rogue dependency that registers with a command-and-control server to offer arbitrary code execution.

Vulnerability from github – Published: 2020-09-03 21:23 – Updated: 2021-09-29 20:22Version 2.0.2 contained malicious code. The package targeted the Ethereum cryptocurrency and performed transactions to wallets not controlled by the user.
Recommendation
Remove the package from your environment. Ensure no Ethereum funds were compromised.

Mitigation
Remove the malicious code and start an effort to ensure that no more malicious code exists. This may require a detailed review of all code, as it is possible to hide a serious attack in only one or two lines of code. These lines may be located almost anywhere in an application and may have been intentionally obfuscated by the attacker.
CAPEC-442: Infected Software
An adversary adds malicious logic, often in the form of a computer virus, to otherwise benign software. This logic is often hidden from the user of the software and works behind the scenes to achieve negative impacts. Many times, the malicious logic is inserted into empty space between legitimate code, and is then called when the software is executed. This pattern of attack focuses on software already fielded and used in operation as opposed to software that is still under development and part of the supply chain.
CAPEC-448: Embed Virus into DLL
An adversary tampers with a DLL and embeds a computer virus into gaps between legitimate machine instructions. These gaps may be the result of compiler optimizations that pad memory blocks for performance gains. The embedded virus then attempts to infect any machine which interfaces with the product, and possibly steal private data or eavesdrop.
CAPEC-636: Hiding Malicious Data or Code within Files
Files on various operating systems can have a complex format which allows for the storage of other data, in addition to its contents. Often this is metadata about the file, such as a cached thumbnail for an image file. Unless utilities are invoked in a particular way, this data is not visible during the normal use of the file. It is possible for an attacker to store malicious data or code using these facilities, which would be difficult to discover.
