CVE-2026-7873 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 attackers can exploit this flaw to execute arbitrary OS commands and access sensitive files, including credentials. The vulnerability has a CVSS 3.1 base score of 9.9, indicating high attack vector accessibility (network), low attack complexity, and no user interaction required. The impact includes full confidentiality, integrity, and availability compromise, enabling complete system takeover and lateral movement. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.

Successful exploitation allows an authenticated attacker to execute arbitrary operating system commands and read sensitive files such as credentials. This leads to complete compromise of the affected system, including confidentiality, integrity, and availability impacts, and may facilitate lateral movement within the network.
