The application discloses a source code pollution detection method, device and equipment and a storage medium. The source code to be detected is subjected to syntax analysis to generate an abstract syntax tree. The type of each node in the abstract syntax tree is determined, and an enhanced control flow graph corresponding to the source code is constructed according to the type of each node. The abstract syntax tree is subjected to sensitive pollution analysis to determine a sensitive data source. The pollution propagation path of the sensitive data source is tracked in the enhanced control flow graph to form a pollution propagation path graph. The pollution propagation path graph is matched with each vulnerability feature graph constructed in advance, a successfully matched vulnerability feature graph is determined, and the line number, pollution type, propagation path and corresponding segment of the pollution in the enhanced control flow graph of the pollution of the source code are determined according to the successfully matched vulnerability feature graph.
