CVE-2026-10295Public exploit

Application hang via unbounded review input

Published Jun 1, 2026 · Updated Jun 1, 2026

Denial of service in SourceCodester Customer Review App 1.0 allows local users to hang the application via oversized review input. The add_review function accepts unbounded name and comment strings, and save_review serializes them directly into reviews.json without length checks. A user with local GUI access can persist multi-megabyte reviews that make later loading and display lag or freeze; direct corruption of the storage file shown by the public PoC falls outside the application input path.
