Vulnerability from github – Published: 2026-06-26 18:33 – Updated: 2026-06-26 18:33

Details

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.

Severity

9.6 (Critical)

CVE-2025-11919 (GCVE-0-2025-11919)

Vulnerability from cvelistv5 – Published: 2026-06-26 15:39 – Updated: 2026-06-26 17:40

Title

Unprotected temporary directories in Wolfram Cloud may result in privilege escalation

Summary

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.
