An OS command injection vulnerability exists in Akaunting v3.1.3 and earlier. An attacker can manipulate the company locale when installing an app to execute system commands on the hosting server.

Akaunting v1.3.17 was discovered to contain a stored cross-site scripting (XSS) vulnerability which allows attackers to execute arbitrary web scripts or HTML via a crafted payload in the Company Name input field.

Akaunting version 2.1.12 and earlier suffers from an authentication bypass issue in the user-controllable field, companies[0]. This issue was fixed in version 2.1.13 of the product.

Akaunting version 2.1.12 and earlier suffers from a password reset spoofing vulnerability, wherein an attacker can proxy password reset requests through a running Akaunting instance, if that attacker knows the target's e-mail address. This issue was fixed in version 2.1.13 of the product. Please note that this issue is ultimately caused by the defaults provided by the Laravel framework, specifically how proxy headers are handled with respect to multi-tenant implementations. In other words, while this is not technically a vulnerability in Laravel, this default configuration is very likely to lead to practically identical identical vulnerabilities in Laravel projects that implement multi-tenant applications.
