Pingvin Share X is a secure and easy self-hosted file sharing platform. From 1.14.1 to 1.16.2, a critical authentication bypass vulnerability allows an attacker who has obtained a valid username and password to skip the second-factor authentication (TOTP) requirement entirely. Although, an attacker still needs the user's password to reach this stage. This vulnerability is fixed in 1.16.3.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, Cacti calls `compat_password_hash` when users set their password. `compat_password_hash` use `password_hash` if there is it, else use `md5`. When verifying password, it calls `compat_password_verify`. In `compat_password_verify`, `password_verify` is called if there is it, else use `md5`. `password_verify` and `password_hash` are supported on PHP < 5.5.0, following PHP manual. The vulnerability is in `compat_password_verify`. Md5-hashed user input is compared with correct password in database by `$md5 == $hash`. It is a loose comparison, not `===`. It is a type juggling vulnerability. Version 1.2.27 contains a patch for the issue.

Owncast is an open source, self-hosted, decentralized, single user live video streaming and chat server. In versions 0.1.2 and prior, a lenient CORS policy allows attackers to make a cross origin request, reading privileged information. This can be used to leak the admin password. Commit 9215d9ba0f29d62201d3feea9e77dcd274581624 fixes this issue.
