CVE-2023-36826Network attack vector

Cross-project artifact disclosure via unscoped file lookup

Published Jul 25, 2023 · Updated Oct 3, 2024

Improper authorization in Sentry 8.21.0 through 23.5.1 allows remote authenticated users to download other projects' debug and artifact bundles. The artifact lookup and debug-file endpoints resolved globally identified files without constraining each lookup to the project named by the route. Exploitation requires a valid account and a known foreign bundle identifier, and the demonstrated consequence is unauthorized file disclosure.
