Summary
Malicious Package in rpc-websocket
Details

Versions of rpc-websocket >= 0.7.6 contained malicious code. The package opens a backdoor to a remote server and executes arbitrary commands, effectively acting as a backdoor.

Recommendation

Any computer that has these versions of the 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.

Summary
Malicious Package in bowe
Details

Version 1.8.4 of bowee contained malicious code as a preinstall script. The package downloaded a file from a remote server, executed it and opened a backdoor.

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.

Severity
9.8 (Critical)

GHSA-XMPW-2VMM-P4P6

Vulnerability from github – Published: 2026-05-19 15:40 – Updated: 2026-06-09 13:13
VLAI
Summary
Malicious code in guardrails-ai 0.10.1 (supply chain compromise)
Details

Impact

On May 11, 2026 at approximately 6:00 PM Pacific, an attacker published a malicious version of guardrails-ai (0.10.1) to PyPI.

Affected: any user who installed guardrails-ai==0.10.1 from PyPI on May 11, 2026.

Security researchers identified the malicious package within approximately 2 hours of publication, and PyPI quarantined the repository. Based on our telemetry, we have observed no requests to Guardrails AI infrastructure originating from the malicious 0.10.1 version, and a review of system and access logs has produced no evidence of user data exfiltration through our systems.

For the full timeline, technical details, and remediation steps we have taken, see SECURITY_ADVISORY.md.

Patches

No patched version above 0.10.1 is available yet. Downgrade to 0.10.0, which is unaffected.

Workarounds

1. Pin to a safe version:

guardrails-ai==0.10.0

2. While the PyPI quarantine is active, install from GitHub:

pip install git+https://github.com/guardrails-ai/guardrails.git@v0.10.0

The v0.10.0 tag in this repository is clean. Track quarantine status here: #1473.

3. If you installed 0.10.1, treat the host as potentially compromised. Rotate any credentials accessible from that machine (GitHub PATs, cloud provider keys, package registry tokens, API keys) and audit your GitHub account for unauthorized workflows or repositories.

4. Snowglobe and Guardrails Hub users : all Snowglobe and Guardrails Hub API keys will be invalidated at 2:00 PM Pacific on May 13, 2026. Rotate yours before then to avoid service interruption.

Mitigation
Implementation Operation

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.
