NVD description

Langflow eval_custom_component_code Eval Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Langflow. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of eval_custom_component_code function. The issue results from the lack of proper validation of a user-supplied string before using it to execute python code. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26972.

    Active Exploitation

    Aikido Intelのレポートを見て「えっ?」となった。 LangflowのCVEが昨日(9/18)上がっている。 CVE-2026-0769。 1月にZDIが未修正の0dayとして公開した、認証不要のRCE。CVSS 9.8。新しい脆弱性ではない。 それが8か月経ってまた目に入ってきた背景には、8月末にVulnCheckが公開した観測がありそうだ。 Langflowについて、2026年だけで悪用確認済みの脆弱性が11件増え、累計12件。 さらにCVE-2026-0769を含む3件だけで、カナリアへの成功した悪用試行が15,000件を超えている。 1件のCVEの話というより、Langflowそのものが継続して狙われている。 これだけ実悪用される脆弱性が続くと、これを基盤にエージェントを組むなら、かなり慎重にならざるを得ない。 Aikido Intel 日次レポート https://aikido-community.jp/intel/aikido-intel-20260919 #サイバーセキュリティ #脆弱性 #Langflow #AIエージェント #CVE #AikidoIntel
