Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | CRITICAL | 9a959283-ebb5-44b6-b705-dcc2bbced522 | ||||
| CVSS 3.1 | CRITICAL | MITRE-CVE |
Solution
Update Langflow to a version that addresses arbitrary code execution vulnerabilities.
- Update IBM Langflow to the latest version.
- Ensure all flow nodes have component type fields.
- Review and sanitize user-provided flow definitions.
- Implement strict validation for all incoming data.
We scan GitHub repositories to detect new proof-of-concept exploits. Following list is a collection of public exploits and proof-of-concepts, which have been published on GitHub (sorted by the most recently updated).
