Overview
Affected versions of this package are vulnerable to SQL Injection through php_pgsql_convert() in ext/pgsql/pgsql.c. An attacker can inject SQL by supplying a crafted value to pg_convert(), pg_insert(), pg_update(), pg_select(), or pg_delete() when PostgreSQL runs with standard_conforming_strings = on. The affected code escapes input with PQescapeStringConn() but wraps it in E'...', allowing a backslash-quote sequence to break out of the string and alter the generated query, which can return unauthorized rows or change inserted and updated data.
