By sending a crafted HTTP request to the exposed endpoint, an attacker can read arbitrary chats from the system, thereby breaching user privacy and potentially gaining sensitive information.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3560576327\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual HTTP request an attacker might use to exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/api\/search\/test?query=&lt;user_id&gt; HTTP\/1.1\nHost: target.librechat.com<\/code><\/pre>\n<p>In this example, `<user_id>` would be replaced with the ID of the target user. Successful exploitation could allow the attacker to read the chat history of the specified user. Note: this is a simplified and conceptual example; actual exploitation would likely involve further complexities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The vulnerability in focus, CVE-2025-54868, targets LibreChat, a popular ChatGPT clone.
