users to execute remote code by uploading malicious files to a temporary directory. This vulnerability arises from improper handling and isolation of temporary files. Additionally, two medium-severity issues were fixed, including one that could disrupt username formatting and another affecting Data Model Acceleration settings. Users are advised to update to the latest versions of Splunk Enterprise to mitigate these risks. The company also patched a high-severity vulnerability in the MCP Server app that exposed user sessions and authorization tokens.
