5 Langflow flaws were confirmed exploited in the wild in the past 365 days. Patch these first.
| Added | Exploited vulnerability | Fix by |
|---|---|---|
| 2026-08-04 | CVE-2026-9198 IBM Langflow IBM Langflow Code Injection Vulnerability Langflow contains a code injection vulnerability that allows unauthenticated attackers to achieve full remote code execution on default Langflow deployments. | 2026-08-07 |
| 2026-07-21 | CVE-2026-0770 Langflow Langflow Langflow Inclusion of Functionality from Untrusted Control Sphere Vulnerability Langflow contains an inclusion of functionality from untrusted control sphere vulnerability that allows remote attackers to execute arbitrary code on affected installations. | 2026-07-24 |
| 2026-07-07 | CVE-2026-55255 Langflow Langflow Langflow Authorization Bypass Through User-Controlled Key Vulnerability Langflow contains an authorization bypass through user-controlled key vulnerability which allows an authenticated attacker to execute any flow belonging to another user by specifying the victim's flow ID in the request. | 2026-07-10 |
| 2026-05-21 | CVE-2025-34291 Langflow Langflow Langflow Origin Validation Error Vulnerability Langflow contains an origin validation error vulnerability in which an overly permissive CORS configuration combined with a refresh token cookie configured as SameSite=None allows a malicious webpage to perform cross-origin requests that include credentials and successfully call the refresh endpoint. This could allow the attacker to execute arbitrary code and achieve full system compromise via obtained tokens that permit access to authenticated endpoints. | 2026-06-04 |
| 2026-03-25 | CVE-2026-33017 Langflow Langflow Langflow Code Injection Vulnerability Langflow contains a code injection vulnerability that could allow building public flows without requiring authentication. | 2026-04-08 |
