info ~~warn~~ → info by review decoder-decompress-payload httpx/_decoders.py:65:29

file imports decoder module(s) codecs, zlib and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
        self.first_attempt = True
        self.decompressor = zlib.decompressobj()

    def decode(self, data: bytes) -> bytes:
```
likely benign LLM, confidence 0.97 httpx's gzip/deflate response decoder initializes a zlib decompressor to handle compressed HTTP response bodies.
Reasoning
This is httpx's standard HTTP content-decoding code. zlib.decompressobj() is used to decompress gzip/deflate response bodies, which is the expected behavior of an HTTP client. The snippet shows a decoder class initializing a zlib decompressor for response data, not an embedded payload being unpacked and executed. The finding's message about a 'embedded payload' is a generic pattern match on decompress calls and does not fit this legitimate library code.

Reproduce This Scan

Run disclude locally to verify. These commands scan the published file; the "new in this release" marks come from comparing it with the previous release's file, which they don't repeat. Add --format sarif for SARIF output. Add --llm (with an API key in the environment) to include the LLM review.
