CVE-2026-18719Network attack vector

Database disclosure and modification via interpolated search

Published Aug 4, 2026 · Updated Aug 4, 2026

SQL injection in cemtan sar2html 4.0.0 allows remote authenticated users to read or alter database data through the search field. The index route inserts the search query parameter directly into a SQLite SELECT statement rather than using a bound parameter. Low application privileges are required; successful injection can expose or change SQLite records and interrupt database-backed searches.
