7.1 HIGH

Description states an authenticated attacker, so PR:L; error-based SQLi primarily discloses data (C:H) with limited integrity and no availability impact.

DescriptionCVE.org

Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in translate_text.php (line 15): SELECT id, filename, extension, type FROM files where id = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.

AnalysisAI

SQL injection in the Guardian language-system (translate_text.php) lets remote attackers extract arbitrary database contents by injecting into the unsanitized 'id' GET parameter. The CVSS 4.0 vector scores this 9.3 (Critical) with PR:N, and the VulnCheck advisory title labels it unauthenticated, though the CVE description states an authenticated attacker is required - this discrepancy should be verified. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Reach translate_text.php endpoint
Delivery
Inject crafted id GET parameter
Exploit
Break out of SQL string literal
Execution
Trigger error-based SQLi in files query
Impact
Extract database contents

Vulnerability AssessmentAI

Exploitation Exploitation requires reachable HTTP access to the translate_text.php endpoint and the ability to supply the 'id' GET parameter, which flows unsanitized into the files-table SQL query. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are strong but partially conflicting. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker sends an HTTP request to translate_text.php with a crafted id parameter (e.g., id=1' AND extractvalue(...)-- ) that breaks out of the SQL string literal, triggering database error messages that leak query results. Using error-based techniques, they iterate payloads to enumerate schemas and dump sensitive table contents such as credentials. …
Remediation No vendor-released patch version is identified in the available data, so no exact upgrade target can be cited. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

24 hours: Disable the translate_text.php endpoint or restrict network access to trusted internal IPs only; confirm current Guardian version and register with vendor for patch notifications. …
