Placer Union High School District notified parents of a data vulnerability involving third-party vendor Total Registration. Student registration data (name, grade, gender, DOB, address, email, parent names) was left viewable in plain text for 48 hours. No SSN or credit card data was exposed. No evidence of unauthorized access was found. The district is evaluating its continued use of the vendor.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
