CVE-2023-32785: Langchain SQL Injection vulnerability

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes langchain (PyPI) < 0.0.247, fixed in 0.0.247. Check your lockfile, including transitive dependencies.

What it is

In Langchain before 0.0.247, prompt injection allows execution of arbitrary code against the SQL service provided by the chain.
