What is CVE-2025-51860?
CVE-2025-51860 is a medium-severity cross-site scripting vulnerability in n/a, published on 22 Jul 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Stored Cross-Site Scripting (XSS) in TelegAI (telegai.com) 2025-05-26 in its chat component and character container component. An attacker can achieve arbitrary client-side script execution by crafting an AI Character with SVG XSS payloads in either description, greeting, example dialog, or system prompt(instructing the LLM to embed XSS payload in its chat response). When a user interacts with such a malicious AI Character or just browse its profile, the script executes in the user's browser. Successful exploitation can lead to the theft of sensitive information, such as session tokens, potentially resulting in account hijacking.
