Unprotected temporary directories in Wolfram Cloud may result in privilege escalation_CVE-2025-11919

{
    "lastseen": "",
    "description": "The default JVM can access files and directories under `/tmp/` including the `$TemporaryDirectory` of other users on the same cloud instance (`/tmp/UserTemporaryFiles/`).  The `-init` file for the the JVM initialization exists in the vulnerable directory during the startup of the JVM.  An attacker with access to the shared `/tmp/` space can preemptively create or replace `.jar` files or directories (via the `-init` file) that the victim JVM will resolve first in its classpath.  By strategically placing a malicious version of a commonly used library (e.g., `commons-io`) in a location that is included in the classpath before the legitimate version, an attacker can cause the JVM to load the malicious class during startup, thereby executing the attacker's code.",
