dartastic_opentelemetry is vulnerable to Insertion of Sensitive Information into Log File
25
Low Risk
This Affects:
dartastic_opentelemetryTL;DR
When debug logging is enabled, the SDK writes OTLP exporter header values to its log output. The environment parser logs the raw OTLP headers environment variable, and the HTTP span and log exporters print every header value except Authorization both at construction and on each export request. Because OTLP headers routinely carry backend credentials such as api-key and vendor authentication tokens, those secrets are recorded in cleartext wherever the SDK log output is collected. The fix redacts all header values by default, logs only header names and counts, and gates value logging behind an explicit allowlist that never includes authorization headers.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run the SDK with debug-level logging enabled while OTLP exporter headers carry credentials.
