Technical Analysis
CVE-2026-97655 is a code injection vulnerability (CWE-94) in IBM Langflow OSS versions 1.0.0 through 1.12.2. The vulnerability arises from an incomplete blocklist in the product's code security scanner, which fails to properly restrict code generation. This allows a remote attacker with low privileges to execute arbitrary code on the affected system without requiring user interaction. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could lead to remote code execution with high impact on confidentiality, integrity, and availability of the affected system. The attacker requires low privileges and no user interaction is needed, increasing the risk of automated or remote attacks.
Mitigation Recommendations
No official patch or remediation information is provided in the vendor advisory or input data. Patch status is not yet confirmed — check the IBM advisory for current remediation guidance. Until a fix is available, restrict access to the affected versions and monitor for suspicious activity related to code execution attempts.
