Arbitrary File Read in Chainlit custom elements
CVE-2025-22218 is an arbitrary file read / information disclosure vulnerability in Chainlit’s custom "elements" attachment feature. According to the provided supporting content, an attacker can use a specific API endpoint to update custom elements so they reference arbitrary files on the server. The application then saves the targeted file into the attacker’s session, after which the attacker can download it. This can expose sensitive local files including configuration files, database files, and application source code. The supplied content appears to conflict with the top-level description referencing VMware Aria Operations for Logs; based on the detailed fact extraction, the vulnerability information provided for CVE-2025-22218 pertains to Chainlit.
