Langflow: Improper Control of Dynamically-Managed Code Resources

CVE-2024-7297 is a high-severity improper control of dynamically-managed code resources vulnerability in Langflow, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.13 as the first without the flaw, so updating Langflow to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 21.2% chance of exploitation within 30 days, which is in the top 2.37% of all scored CVEs.

The underlying weakness: Improper Control of Dynamically-Managed Code Resources

The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.

How developers prevent this class of flaw

  • For any externally-influenced input, check the input against an allowlist of acceptable values.
  • Refactor the code so that it does not need to be dynamically managed.
