Description OSIDB Bzimport 2026-07-20 18:02:18 UTC 
Due to a missing sanitization call in [`afsql_dd_run_query`](https://github.com/syslog-ng/syslog-ng/blob/649e6e18e3459fb4467000a88dfb12fa97f9719c/modules/afsql/afsql.c#L219), syslog-ng before 4.12 are vulnerable to SQL injection from an untrusted source. This is not part of the default configuration, the SQL driver has to be manually configured.

Fixes are in syslog-ng 4.12, syslog-ng Premium Edition 8.2 and syslog-ng Store Box 7.8
