Unauthenticated SQL injection via unchecked sort expression
Published Sep 2, 2025 · Updated Sep 2, 2025
SQL injection in FireShare FileShare 1.2.25 allows remote attackers to read or alter database data through the public video sort parameter. The public-video endpoint inserts the unvalidated sort expression into a SQL ORDER BY clause, permitting arbitrary subqueries and time-based inference. No authentication or user interaction is required, and the demonstrated timing oracle exposes database contents while injected SQL can affect data integrity.
