CVE-2026-22008 is a difficult-to-exploit vulnerability in the Libraries component of Oracle Java SE 25.0.1. In Java client deployments that execute untrusted code through sandboxed Java Web Start applications or sandboxed Java applets, an unauthenticated network-accessible attacker may compromise the integrity of data accessible to the Java deployment. Oracle identifies the issue as involving improved Arena allocations; no further vulnerable-code or root-cause details are available.

This repository is a small proof-of-concept/operational exploit demo for CVE-2026-22008, illustrating AWS Lambda layer injection through use of an untrusted public layer ARN. The repository contains 4 files: a LICENSE, a README describing the issue and usage, a deployment script (deploy_vulnerable_lambda.py), and a malicious layer payload (malicious_layer/payload.py). The main exploit flow is straightforward: the deployment script uses boto3 to create a Lambda function named 'victim-func' with runtime python3.9, assigns it an IAM role, loads code from a local function.zip, and attaches a public layer ARN controlled by another account. The malicious layer payload defines a handler that invokes curl to POST the Lambda environment variables to http://attacker.com/steal, demonstrating credential or secret exfiltration from the function runtime. Structurally, the repo is minimal and purpose-built to demonstrate the security risk of trusting third-party/public Lambda layers. It is not a scanner or detector; it actively sets up a vulnerable function configuration and includes a working exfiltration payload. The exploit capability is cloud/supply-chain compromise of AWS Lambda workloads via malicious dependency injection, with network exfiltration as the post-compromise action.
