• CVE-2026-119210: 0.30% estimated exploitation activity in the next 30 days; percentile 23.12 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary MariaDB Connector/J checked a server's LOAD DATA LOCAL INFILE file request by searching the text of the command it had sent for `LOAD DATA LOCAL INFILE ' '`. The search also matched inside quoted identifiers, string literals and comments, so text returned by the server and re-used in a later query could satisfy it. A rogue or MitM server can read any file the client JVM can read.

Details When a server answers a command with a LOCAL INFILE request (`0xFB` packet), the connector opens the named file on the client host and streams it to the server, after verifying that the file corresponds to a `LOAD DATA LOCAL INFILE` of the command it sent (`ClientMessage.validateLocalFileName()`). That verification was a regular expression whose prefix accepted any character, so it answered "does the text appear anywhere in the SQL", including inside a backtick-quoted identifier. Several driver paths put identifiers returned by the server straight back into their next query:…

# Patch Next advisory brief: CVE-2026-119210

Advisory: MariaDB Connector/J: LOAD DATA LOCAL INFILE file check could be satisfied by text inside quoted identifiers, letting a malicious server read client files
IDs: CVE-2026-119210, GHSA-fhx5-2xqw-2cgm
Record: https://patchnext.com/advisories/cve-2026-119210 (revision 2, source checked 31 Oct 2026, 07:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.mariadb.jdbc:mariadb-java-client 3.5.11, 3.4.5, 3.3.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.mariadb.jdbc:mariadb-java-client: affected >= 3.0.0, < 3.3.7; >= 3.4.0, < 3.4.5; >= 3.5.0, < 3.5.11; fixed in 3.5.11, 3.3.7, 3.4.5

## Suggested inspection (read-only)
- Maven org.mariadb.jdbc:mariadb-java-client: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.mariadb.jdbc:mariadb-java-client.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
