OAuth nonce prediction via insecure random generation
Published Apr 5, 2025 · Updated Sep 5, 2025
Insufficient entropy in Net::Dropbox::API 1.9 and earlier allows attackers to predict OAuth nonce values generated for API requests. The nonce method calls Data::Random for character generation, whose default source ultimately uses Perl's predictable rand function instead of a cryptographic generator. Exploitation requires user interaction and low-privileged network access; the published record does not demonstrate a specific end-to-end compromise.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.9
