# CVE-2026-63417: Logging Redactor: PII data in str/repr of non primitive objects was not being redacted

Status: published. Published: 2026-11-03. Updated: 2026-11-09.

Logging Redactor is a Python library designed to redact sensitive data in logs based on regex patterns and / or dictionary keys. Prior to 0.0.7, personally identifiable information returned by custom object __str__ or __repr__ methods is not redacted when such non-primitive objects are logged, causing sensitive values to appear in logs that are expected to mask them. This issue is fixed in version 0.0.7.

## Remediation
