Non-root user that (suddenly) has elevated privileges in a specific command (only). [Have I been hacked?] (lemmy.world)

Title. Long,short story: creating or editing files with nano as my non-root user gives (the file) elevated privileges, like I have ran it w/ sudo or as root. And the (only) "security hole" that I can think of is a nextdns docker container running as root. That aside, its very "overkill" security-wise (cap_drop=ALL, non-root image, security_opt=no_new_privileges, etc.).

It's like someone tried to hack me but gave up halfway. Am I right or wrong to assume this? Just curious.

Thanks in advance.

Do you run docker container in privileged mode? https://phoenixnap.com/kb/docker-privileged

And do you run nano inside the container?

Docker container running in privileged mode has root permissions to host filesystem and devices (limited by said restrictions).

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
