fix(pii): Scrub API key headers with hyphens (e.g. x-api-key)#5829
Conversation
The PASSWORD_KEY_REGEX matched `api_key` and `apikey` but not `api-key`, so HTTP headers like Anthropic's `x-api-key` were not scrubbed by default data scrubbing. Update the regex to use `api[-_]key` (and `private[-_]key` for consistency) to cover hyphenated header names.
