1 valid exploit after Mallory filtered fakes, detection scripts, and README-only repos.
The repository contains a README and one Python proof-of-concept program, poc.py. The script accepts a target Langflow base URL, username, password, and Bash command. It first POSTs credentials to /api/v1/login, extracts the access_token from a successful JSON response, and uses it as a Bearer token. It then POSTs a JSON code field to /api/v1/validate/code containing crafted Python. The injected code launches /bin/bash -c with the operator-provided command via subprocess.run(shell=True), captures stdout/stderr, and exposes that output by raising an exception. This is an authenticated remote command-execution exploit claimed to target CVE-2026-7873 in Langflow 1.0.0–1.10.0; it is not a detection-only script and contains no framework integration.
