Hi,

The following vulnerability was published for gradle.

CVE-2021-32751[0]:
| Gradle is a build tool with a focus on build automation. In versions
| prior to 7.2, start scripts generated by the `application` plugin and
| the `gradlew` script are both vulnerable to arbitrary code execution
| when an attacker is able to change environment variables for the user
| running the script. This may impact those who use `gradlew` on Unix-
| like systems or use the scripts generated by Gradle in thieir
| application on Unix-like systems. For this vulnerability to be
| exploitable, an attacker needs to be able to set the value of
| particular environment variables and have those environment variables
| be seen by the vulnerable scripts. This issue has been patched in
| Gradle 7.2 by removing the use of `eval` and requiring the use of the
| `bash` shell. There are a few workarounds available. For CI/CD systems
| using the Gradle build tool, one may ensure that untrusted users are
| unable to change environment variables for the user that executes
| `gradlew`. If one is unable to upgrade to Gradle 7.2, one may generate
| a new `gradlew` script with Gradle 7.2 and use it for older versions
| of Gradle. Fpplications using start scripts generated by Gradle, one
| may ensure that untrusted users are unable to change environment
| variables for the user that executes the start script. A vulnerable
| start script could be manually patched to remove the use of `eval` or
| the use of environment variables that affect the application's
| command-line. If the application is simple enough, one may be able to
| avoid the use of the start scripts by running the application directly
| with Java command.
