Description
A library injection vulnerability exists in Microsoft Teams (work or school) 24046.2813.2770.1094 for macOS.

A malicious application could inject a library and start the program to trigger this vulnerability and then make use of the vulnerable application's permissions.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. A reference of the record is tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
