SCA: security update for dev.langchain4j:langchain4j-mariadb, dev.langchain4j:langchain4j-pgvector (GHSA-2mfg-cc43-9pcj)

high Tenable Self-Hosted Container Security Plugin ID 443349

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - LangChain4j is a Java library for building LLM-powered applications on the JVM. Prior to 1.2.1-beta8,
 1.5.1-beta11, 1.11.8-beta19, and 1.16.3-beta26, the MariaDB and pgvector embedding stores build metadata-
 filter SQL by string-concatenating filter keys, and in MariaDB string values, directly into the query
 without adequate escaping. A crafted metadata key in EmbeddingSearchRequest.filter() can break out of its
 SQL context and inject arbitrary SQL into the statements executed by the stores' search and
 removeAll(Filter) operations, enabling blind data exfiltration, denial of service via sleep functions, and
 deletion of arbitrary rows through removeAll(Filter). This issue is fixed in langchain4j-mariadb and
 langchain4j-pgvector versions 1.2.1-beta8, 1.5.1-beta11, 1.11.8-beta19, and 1.16.3-beta26.
 (CVE-2026-55405)

Solution

Update the dev.langchain4j:langchain4j-mariadb library and its related packages to version 1.11.8-beta19 or later.
