CVE-2026-39879
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
Missing sanitization in afsql_dd_run_query in syslog-ng before 4.12 leads to SQL injection from an untrusted source. Not in default configuration, requires manual SQL driver setup. Fixed in syslog-ng 4.12, Premium Edition 8.2, and Store Box 7.8.
Risk Assessment
Risk involves potential unauthorized SQL queries by an attacker, which could lead to data leakage or manipulation in the database.
Recommendation
Upgrade syslog-ng to version 4.12 or later and restrict SQL driver access to trusted sources only.

Original NVD description (English source)
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
