Package : grunt
Version : 1.0.1-8+deb10u2
CVE ID : CVE-2022-1537

It was discovered that there was a potential local privilege
escalation in GruntJS, a multipurpose task runner and build system
tool.

file.copy operations in GruntJS were vulnerable to a TOCTOU
("time-of-check vs. time-of-use") race condition that could have led
to arbitrary file writes in GitHub repositories. This could have then
led to local privilege escalation if a lower-privileged user had
write access to both source and destination directories, as the
lower-privileged user could have created a symlink to the GruntJS
user's ~/.bashrc configuration file (etc).

For Debian 10 buster, this problem has been fixed in version
1.0.1-8+deb10u2.

We recommend that you upgrade your grunt packages.
