Java's default locale conversion, especially Turkish, alters the lowercase letter i to a dotted capital I (\u0130). The application filters out risky parameters using this locale\u2011dependent conversion, while the underlying H2 engine normalizes URLs with the English locale.

The EPSS score of less than 1% indicates that, although the flaw is serious, exploit attempts are currently rare. The issue is not listed in the CISA KEV catalog, suggesting no widespread exploitation yet. Exploitation requires the runtime JVM to operate under a Turkish locale; an attacker who can influence the server\u2019s locale setting or deliver the payload via a remote Java application can bypass the validation and execute arbitrary SQL commands."}}}}, "created": "2026-03-20T08:52:51.041296+00:00", "updated": "2026-03-25T14:09:29.108089+00:00", "vendors": ["dataease", "dataease$PRODUCT$dataease"]}
