Low risk12th percentile - higher than 12% of all known CVEs
Summary
IBM Langflow OSS versions 1.0.0 through 1.11.5 is vulnerable to server-side request forgery (SSRF). This may allow an unauthenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.
Risk Assessment
An unauthenticated attacker could exploit SSRF to scan the internal network or conduct further attacks from the vulnerable system. This may lead to disclosure of infrastructure information and an increased attack surface.
Recommendation
Update IBM Langflow OSS to a version later than 1.11.5 or apply the vendor fix. Restrict the system's network access and implement validation of outbound requests.
Other vulnerabilities in IBM Langflow OSS
See all- CVE-2026-93680Critical
IBM Langflow OSS versions 1.0.0 through 1.12.8 contain an improper authentication flaw that could allow a remote attacker to bypass security restrictions.
- CVE-2026-110186Critical
IBM Langflow OSS 1.0.0 through 1.12.8 could allow a remote attacker to execute arbitrary code due to improper control of code generation.
- CVE-2026-107329Critical
IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to improper control of code generation.
- CVE-2026-107328Critical
IBM Langflow OSS 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to improper neutralization of code in eval/exec.
- CVE-2026-107327Critical
IBM Langflow OSS versions 1.0.0 through 1.12.4 could allow a remote authenticated attacker to execute arbitrary code due to missing authorization.
- CVE-2026-104339Critical
IBM Langflow OSS versions 1.0.0 through 1.12.3 could allow a remote attacker to execute arbitrary code due to improper neutralization of special elements used in an OS command.
- CVE-2026-12944Critical
IBM Langflow OSS 1.0.0 through 1.10.0 allows attackers to execute arbitrary Python code with root privileges (UID=0) on the Langflow server by submitting components containing socket or urllib imports. This enables AWS credential theft via IMDSv1 SSRF, arbitrary file exfiltration from the container filesystem, and lateral movement to internal services (PostgreSQL, Redis) within the Docker network. The scanner incorrectly returns "validated": true, providing a false security signal.
- CVE-2026-81204Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow a remote attacker to execute arbitrary code due to code injection during graph construction.
- CVE-2026-79724Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command.
- CVE-2026-85025Critical
IBM Langflow OSS versions 1.0.0 through 1.11.5 allow an unauthenticated attacker to execute arbitrary code and access or modify chat sessions through publicly shared MCP project endpoints due to improper enforcement of public-flow security restrictions and session isolation controls.
