Tracker
Named security defects in Dropbox's software — plus documented abuse of its platform — with severity, status, and sources. A serious record tracks the identifier-bearing flaws, not only the headline breaches.
CVE-2024-5924MediumPatched2024Files arriving via Dropbox sync could be written without the Windows 'Mark of the Web' flag, stripping SmartScreen/Protected-View warnings that protect users from running downloaded, untrusted content. Remediated in current client releases.
Affected: Dropbox desktop (Windows)
Platform abuse (C2)MediumOngoing2024Not a flaw in Dropbox, but a recurring abuse: state-aligned groups (e.g. Kimsuky, ScarCruft) use the trusted Dropbox API as a command-and-control and exfiltration channel that blends into normal enterprise traffic.
Affected: Dropbox API
