| Título | pytries datrie 0.8.3 Deserialization |
|---|
| Descrição | The `datrie.Trie` class uses `pickle.load()` to deserialize internal data when loading trie files via `Trie.load()`, `Trie.read()`, and `Trie.__setstate__()`. A crafted `.trie` file can embed a malicious pickle payload that executes arbitrary Python code when the file is loaded. Users have no indication that loading a `.trie` file involves code execution, as the unsafe deserialization is hidden behind a data-loading API. The `datrie.BaseTrie` class is not affected as it does not use pickle. Any application that loads `.trie` files from untrusted sources (user uploads, shared storage, downloaded datasets) is vulnerable to arbitrary code execution. |
