CVE-2026-8635: CWE-94 Improper Control of Generation of Code ('Code Injection') in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.10.0 allows authenticated users to escalate privileges to superuser by directly manipulating the database, execute arbitrary system commands, and achieve full system compromise with Langflow service permissions.
AI Analysis
Technical Summary
CVE-2026-8635 is a critical vulnerability in IBM Langflow OSS (versions 1.0.0 through 1.10.0) involving improper control of code generation (CWE-94). Authenticated users can exploit this weakness to escalate privileges to superuser by directly manipulating the database, allowing them to execute arbitrary system commands. This results in complete system compromise under the Langflow service's permissions. The vulnerability has a CVSS 3.1 base score of 9.9, indicating a high-impact remote attack vector with low attack complexity and no user interaction required.
Potential Impact
Successful exploitation allows an authenticated attacker to gain superuser privileges, execute arbitrary system commands, and fully compromise the affected system with the permissions of the Langflow service. This can lead to unauthorized access, data manipulation, and control over the host environment.
Mitigation Recommendations
Patch status is not yet confirmed — no official fix or remediation guidance is currently available from IBM. Users should monitor IBM's advisories for updates and consider restricting access to the Langflow OSS service to trusted users only until a patch is released.
