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 AI agent calculator tool that evaluates a math expression with eval after character filtering.
Reasoning
eval on a user-influenced expression is a genuine code-execution risk, but this is an example calculator tool; the code first validates characters (the snippet shows an invalid-characters return), and the context is a demo. Still unsafe pattern, so suspicious rather than malicious.
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 single-agent calculator tool using eval on a sanitized arithmetic expression.
Reasoning
Identical to multi_agent.py: eval of a filtered arithmetic expression in an example agent. Unsafe practice in a demo, 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-frame walk in PostHog exception utilities to collect traceback context.
Reasoning
sys._getframe is standard for stack walking in exception reporting utilities; the loop with ValueError handling is typical frame-depth probing with no payload or evasion.
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 session token for wire-format comparison.
Reasoning
A base64url-looking string in a test fixture encoding a JSON session token with readable fields (sid, cn, cv, pv); the test comments indicate wire-format compatibility checks. 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 0.95 Unit test decompressing and checking a captured zlib-compressed request body.
Reasoning
Test asserting zlib round-trip of a captured request body to verify api_key is absent; decompressing a payload the test itself produced. Not runtime malicious payload execution.
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 that gunzips and parses a mocked HTTP request body.
Reasoning
Test helper decompressing gzip request bodies captured from mocks to assert JSON contents. Routine 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 Unit test verifying gzip-compressed request payload contents.
Reasoning
Test asserting on gzip-decompressed batch body fields such as api_key. Ordinary test verification of request encoding.
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 Tracing test helper decompressing gzip body from a mocked POST call.
Reasoning
Test helper gunzipping mocked session.post data to inspect the sent JSON. Routine test code with 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 0.95 Tracing transport test checking gzip-decompressed payload equality.
Reasoning
Test asserting the gunzipped request body equals the expected payload. Ordinary test code.
