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 A calculator tool in an example agent passes a filtered expression to eval.
Reasoning
eval is called on a user/model-supplied expression after the code checks for invalid characters; this is a real code-execution risk from an LLM tool, but it is a sample calculator, not hidden malicious intent. The character filter is weak, so it is a genuine security weakness rather than obfuscation.
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 A single-agent example calculator tool uses eval on a filtered expression.
Reasoning
Same eval-based calculator pattern as multi_agent.py in an example directory; the eval is on a filtered expression and is a known unsafe-sample pattern, 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 0.85 Walks the call stack with sys._getframe to gather frame information for exception reporting.
Reasoning
sys._getframe with a depth counter is a standard, legitimate technique used in exception utilities to walk the stack for module/context information.
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 A base64-encoded JSON session token fixture used in a test.
Reasoning
A short base64 JSON literal in a test fixture decoding to session metadata; the comment shows it is a wire-format test vector, not a hidden 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 0.92 A test decompresses a captured zlib payload to check its contents.
Reasoning
zlib.decompress in a test verifying a compressed request body round-trips and omits the API key; it is test assertion logic on the test's own data.
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 0.92 A test helper decompresses a mocked gzip request body to inspect JSON.
Reasoning
gzip.decompress of a mocked request body in a test helper, parsing 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 0.92 A unit test decompresses gzip request data to assert payload fields.
Reasoning
gzip.decompress of captured request data in a unit test checking batch and api_key fields; standard 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 0.92 A tracing test helper decompresses a mocked gzip body for inspection.
Reasoning
Test helper decompressing a mocked gzip POST body to return parsed JSON for assertions; no runtime payload execution.
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 0.92 A transport test decompresses gzip data to compare it with an expected payload.
Reasoning
gzip.decompress used to verify the transport payload equals the expected fixture in a test; benign test code.
