LoggerJS handles application logs, error payloads, redaction, and offline delivery. Please report security issues privately before publishing details.

LoggerJS is pre-1.0. Security fixes target the latest released minor line only. Older 0.x releases may receive fixes when the patch is low-risk, but users should expect to upgrade to the newest 0.x release for security updates.

Use GitHub private vulnerability reporting for github.com/jskits/loggerjs when available. Include:

• affected package and version,
• a minimal reproduction or attack string,
• expected impact,
• whether the issue is already public.

If private reporting is unavailable, open a public issue that asks for a secure contact path without including exploit details.

• Initial acknowledgement: within 7 days.
• Triage decision: within 14 days when a reproduction is provided.
• Fix and advisory timing: coordinated with the reporter based on severity and release risk.

Security-sensitive areas include:

• privacy/redaction processors,
• codecs and serialization fallbacks,
• browser persistence and offline replay,
• transport retry, batching, and queue behavior,
• vendor signing or authentication helpers,
• prototype pollution, ReDoS, and denial-of-service inputs.

The two redaction processors cover different threats, and most apps want both:

• redactProcessor is key-based: it masks values whose key or path matches your keys/paths — including keys carried on Error own properties and inside Map/Set. It does not inspect free-text values.
• privacyGuardProcessor is value-based: it scans string content for patterns (emails, tokens, card numbers, custom regexes) regardless of key.

By design, redactProcessor preserves Error message/stack strings verbatim (they are not keys). If those may contain secrets or PII — e.g. an error message that embeds a token, or a stack with an email address — pair it with privacyGuardProcessor, which scans raw Error message/stack strings before serialization. Neither processor scans values inside opaque/binary payloads or already-stringified blobs; redact before serialization, not after.
