A library injection vulnerability exists in the WebView.app helper app of Microsoft Teams (work or school) 24046.2813.2770.1094 for macOS. A specially crafted library can leverage Teams's access privileges, leading to a permission bypass. 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.

An issue was discovered in password-store.sh in pass in Simple Password Store 1.7.x before 1.7.2. The signature verification routine parses the output of GnuPG with an incomplete regular expression, which allows remote attackers to spoof file signatures on configuration files and extension scripts. Modifying the configuration file allows the attacker to inject additional encryption keys under their control, thereby disclosing passwords to the attacker. Modifying the extension scripts allows the attacker arbitrary code execution.

An Insufficient Verification of Data Authenticity vulnerability in B. Braun SpaceCom2 prior to 012U000062 allows a remote unauthenticated attacker to send the device malicious data that will be used in place of the correct data. This results in full system command access and execution because of the lack of cryptographic signatures on critical data sets.
