Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Data Integrity: Unauthorized deletion of records in Kinto during CSV uploads directly corrupts stored data; the fix added an allow_delete flag, indicating destructive operations were not properly gated by default.
Denial of Service: SpaCy's memory growth from arbitrary search terms could exhaust memory, causing service unavailability; the fix introduced a memory zone and periodic reload, suggesting unbounded resource consumption on user-controlled input.
Information Disclosure: Sentry events captured query parameters, potentially leaking user search terms to third-party monitoring; the before_send filter strips sensitive data, indicating a lack of default data minimization.
