CVE-2026-110595
BottleCRM 0.45 through 1.14.5 Memory Exhaustion via Contact and Case CSV Import
Description
BottleCRM 0.45 through 1.14.5 contains an uncontrolled memory allocation vulnerability in _read_upload() that reads entire CSV uploads before enforcing the 5 MB limit. Authenticated users with mass-import permission can send oversized CSV files concurrently to /api/contacts/import/ and /api/cases/import/ endpoints to exhaust worker memory and trigger out-of-memory termination.
