CVE-2026-112180 · Severity: info · Published 2026-10-19

MISP is a threat intelligence sharing platform used by security teams to coordinate detection and response. When users delete events from MISP, associated sensitive data such as correlation mappings, scan results, and report metadata are not removed from the database, leaving orphaned records that may be inadvertently exposed. An authenticated user with event deletion privileges can trigger this flaw, causing threat intelligence data to persist beyond its intended lifecycle and creating a data retention risk.

## How to fix

- Fixed in 2.5.48

## Technical details

This is an incomplete deletion vulnerability in MISP's event deletion logic affecting the Event model. When an event is deleted, orphaned records are left behind in multiple tables including event_report_tags, event_graphs, proposal correlations, fuzzy ssdeep chunks, and attachment scan results. An authenticated user with sufficient privileges can delete events, and if these associated records exist, they persist in the database and may be accessible through other query paths that do not validate parent event existence.
