Summary
Flamingo (aka FlamingoIM) through 2020-09-29 allows ../ directory traversal because the only ostensibly unpredictable part of a file-transfer request is an MD5 computation; however, this computation occurs on the client side, and the computation details can be easily determined because the product's source code is available.
Exploit prediction
1.64% chance of exploitation in the next 30 days, higher than 76% of all scored CVEs (FIRST EPSS, 2026-11-08).
