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 0.85 Example calculator tool evaluates a user-supplied math expression with eval after replacing ^ with **.
Reasoning
eval is applied to an expression string after only a character-whitelist check in the example calculator tool; this is a real code-injection risk pattern in a sample, but it is a well-known demo mistake rather than hidden malicious intent. Flagging as suspicious because the eval is on model/user-provided input, not an obfuscated payload.
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 0.85 Example calculator tool evaluates a user-supplied math expression with eval.
Reasoning
Same eval-based calculator as multi_agent.py in a sample directory; insecure example code with a character filter, 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 0.80 Walks the call stack via sys._getframe to collect frame information for exception reports.
Reasoning
sys._getframe with a depth counter inside a try/except ValueError is the standard idiom for walking the stack to collect frames for exception reporting. Legitimate SDK behavior.
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 0.90 Base64 test fixture encoding a small JSON session token in a unit test.
Reasoning
The blob is a short base64url-encoded JSON test fixture (sid, cn, cv, pv fields) used to check encoding byte-identity in a test file. Plain test data, not a payload.
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 0.95 Test decompresses its own captured request body to assert the API key is not leaked.
Reasoning
In a test, zlib.decompress is used to round-trip a request body the test itself produced and verify api_key is absent. No embedded payload executed.
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 0.95 Test helper decompresses and parses a gzip-encoded mock request body.
Reasoning
Test helper gunzips a captured mock request body to parse JSON for assertions. Ordinary 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 0.95 Test decompresses a captured gzip request body to check its contents.
Reasoning
Unit test gunzips and JSON-parses a request body to check batch and api_key fields. Normal test verification.
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 0.95 Test helper gunzips a mocked POST body to inspect the JSON payload.
Reasoning
Test helper gunzips mock POST data for assertions. Standard test scaffolding.
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 0.95 Test checks that a gzip-compressed request body decodes to the expected payload.
Reasoning
Test asserts the gzip-decompressed request body equals the expected payload. Routine test verification.
