Arbitrary code execution via unescaped deployment values
Published Jul 15, 2026 · Updated Jul 15, 2026
Code injection in PraisonAI before 4.6.78 allows attackers to execute arbitrary Python through malicious deployment configuration. generate_api_server_code() inserts deploy.api.host and agents_file values into generated Python string literals without safe encoding, allowing expression splices to alter the source. Exploitation requires an operator to deploy the malicious project; injected code then runs with the deploy process's access at server startup or route evaluation.
