Signals

Ordered by severity, then signals introduced in this release. Hidden characters are shown as ⟨U+…⟩.

warn dynamic-execution examples/example-ai-openai-agents/multi_agent.py:29:23

`eval` called on a non-literal expression (ast pass, confidence 0.70)
```
        return "Error: invalid characters"
    return f"Result: {eval(expression.replace('^', '**'))}"
```
suspicious LLM, confidence 0.80 Calculator tool in an example agent passes a sanitized expression string to eval.
Reasoning
eval is called on an expression derived from user/LLM input after replacing ^ with **. This is a genuine code-injection risk in an example, though the snippet shows a character check earlier (the 'invalid characters' return) that partly restricts input. Still a poor pattern worth flagging.
warn dynamic-execution examples/example-ai-openai-agents/single_agent.py:29:23

`eval` called on a non-literal expression (ast pass, confidence 0.70)
```
        return "Error: invalid characters"
    return f"Result: {eval(expression.replace('^', '**'))}"
```
suspicious LLM, confidence 0.80 Single-agent example calculator evaluates a filtered expression with eval.
Reasoning
Same eval-based calculator as multi_agent.py, with an earlier invalid-character guard. Risky pattern in example code, not evidence of malicious intent.
info ~~warn~~ → info by review frame-introspection posthog/exception_utils.py:1060:21

`sys._getframe` — call-stack frame introspection (ast pass, confidence 0.70)
```
        try:
            frame = sys._getframe(depth)
            depth += 1
        except ValueError:
```
likely benign LLM, confidence 0.90 Stack walking helper that reads frames up to a depth until ValueError.
Reasoning
sys._getframe with a depth counter inside a try/except ValueError is the standard way to walk the stack for exception context in a logging/telemetry library. Legitimate.
info ~~warn~~ → info by review encoding-base64 posthog/test/mcp/test_session_token.py:68:15

base64-like blob (95 bytes, compression ratio 1.12) (raw pass, confidence 0.60)
```
    )
    frozen = "eyJzaWQiOiJzZXNfZml4dHVyZSIsImNuIjoiQ2xhdWRlIENvZGUiLCJjdiI6IjEuMi4zIiwicHYiOiIyMDI1LTA2LTE4In0"

    # Encode side: our output is byte-identical to the shared wire format.
```
likely benign LLM, confidence 0.92 Test fixture containing a base64 encoded JSON session token.
Reasoning
The string is a base64url-encoded JSON fixture (decodes to session/client metadata) in a test asserting wire-format compatibility. Plain test data, not obfuscation.
info ~~warn~~ → info by review decoder-decompress-payload posthog/test/test_capture_v1.py:456:24

file imports decoder module(s) zlib and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
        self.assertEqual(call["data"][0], 0x78)  # zlib header
        roundtripped = zlib.decompress(call["data"]).decode("utf-8")
        self.assertNotIn("api_key", json.loads(roundtripped))
```
likely benign LLM, confidence 0.93 Test roundtrips a zlib-compressed capture payload to check its contents.
Reasoning
Test decompresses its own zlib-compressed request body to assert the api_key is absent. Normal test verification of an outgoing payload.
info ~~warn~~ → info by review decoder-decompress-payload posthog/test/test_metrics.py:55:23

file imports decoder module(s) gzip and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
    body = kwargs.get("data")
    return json.loads(gzip.decompress(body).decode("utf-8"))
```
likely benign LLM, confidence 0.93 Test helper gunzips and parses a captured request body.
Reasoning
Helper decompresses a gzip request body captured from a mock to parse JSON for assertions. Standard test code.
info ~~warn~~ → info by review decoder-decompress-payload posthog/test/test_request.py:227:27

file imports decoder module(s) gzip, zlib and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
        self.assertEqual(headers["Content-Encoding"], "gzip")
        body = json.loads(gzip.decompress(data))
        self.assertEqual(body["batch"], [])
        self.assertEqual(body["api_key"], TEST_API_KEY)
```
likely benign LLM, confidence 0.93 Request test decompresses gzip body to verify its JSON contents.
Reasoning
Test gunzips captured request data to check batch and api_key fields. Ordinary test assertion logic.
info ~~warn~~ → info by review decoder-decompress-payload posthog/test/tracing/test_client_traces.py:60:23

file imports decoder module(s) gzip and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
    args, kwargs = session.post.call_args
    return json.loads(gzip.decompress(kwargs["data"])), args[0], kwargs
```
likely benign LLM, confidence 0.93 Tracing test helper decompresses gzip payload from mock call args.
Reasoning
Helper gunzips mocked session post data for test inspection. Ordinary test code.
info ~~warn~~ → info by review decoder-decompress-payload posthog/test/tracing/test_transport.py:71:27

file imports decoder module(s) gzip and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
```
        assert kwargs["headers"]["Content-Type"] == "application/json"
        assert json.loads(gzip.decompress(kwargs["data"])) == PAYLOAD

    def test_falls_back_to_the_default_timeout(self):
```
likely benign LLM, confidence 0.93 Transport test checks gzip-compressed JSON payload equals expected data.
Reasoning
Test decompresses the gzip body passed to a mocked post and compares to the expected payload. Routine test verification.
