{"id":"CVE-2026-69256","published":"2026-08-04T17:17:00.707","lastModified":"2026-08-05T14:17:10.587","description":"Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the CSVAgent node allowed users to provide Python code that is executed through pyodide; although a denylist blocked dangerous Python constructs, pandas.read_pickle() could deserialize a pickled payload and achieve code execution without matching the denied words. The affected file is flowise-components/nodes/agents/CSVAgent/CSVAgent.ts, where user-supplied customReadCSVFunc is evaluated as pd.${customReadCSVFunc}. An authenticated user who can create or modify a chatflow can add a CSV Agent, place a malicious read_pickle payload in the Additional Parameters, save the chatflow, and trigger /api/v1/prediction/<UUID> to execute commands. This issue is fixed in version 3.1.3.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-94"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FlowiseAI/Flowise/commit/c79fe56a6c249850e96bce9b4859f7a0083e4507","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/pull/6257","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g","tags":[]}],"exploitRefs":[{"url":"https://github.com/FlowiseAI/Flowise/commit/c79fe56a6c249850e96bce9b4859f7a0083e4507","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/pull/6257","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x6vm-w76m-8j7g","tags":[]}],"hasPoc":true,"ai":null}
