CVE-2026-34099 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in job_info.php (line 16): SELECT * FROM jobs where id = '\".$_GET['id'].\"'. No authentication is required. An unauthenticated attacker can perform error-based SQL injection to extract the database version, current user, schema names, and table contents.
Why this priority
- Critical severity
- CISA SSVC: public proof of concept
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
