      <title>CVE-2026-97869 — langchain4j LangChain4j-agentic AgenticScopeJsonSerializationIT.java AgenticScopeSerializer.fromJson deserialization</title>
      <link>https://db.gcve.eu/vuln/cve-2026-97869</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; langchain4j&lt;/p&gt;
&lt;p&gt;A flaw has been found in langchain4j up to 1.5.3-beta10/1.11.10-beta18/1.18.1-beta27. This vulnerability affects the function AgenticScopeSerializer.fromJson of the file AgenticScopeJsonSerializationIT.java of the component LangChain4j-agentic. This manipulation causes deserialization. Remote exploitation of the attack is possible. The attack&amp;#39;s complexity is rated as high. It is stated that the exploitability is difficult. The exploit has been published and may be used. Upgrading to version 1.5.3-beta11, 1.11.10-beta19 and 1.18.1-beta28 is able to resolve this issue. Upgrading the affected component is advised. The project maintainer kindly explains: &amp;#34;The issue was reported to us privately on 23 July 2026 and fixed in releases published on 29 July 2026. It is tracked as GHSA-gmwr-7wmf-mrjm. Exploitation requires an application to have enabled AgenticScope persistence, which is opt-in, and an attacker who can already write to that store. All maintained release lines have been patched.&amp;#34;&lt;/p&gt;</description>
