Haystack is an end-to-end LLM framework that allows you to build applications powered by LLMs, Transformer models, vector search and more. Haystack clients that let their users create and run Pipelines from scratch are vulnerable to remote code executions. Certain Components in Haystack use Jinja2 templates, if anyone can create and render that template on the client machine they run any code. The vulnerability has been fixed with Haystack 2.3.1.
CVE-2024-41950
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 3.1%, top 13% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
