TastyIgniter through 4.4.5 contain a PHP object injection vulnerability that allows authenticated administrators to achieve arbitrary code execution by submitting a serialized PHP object as a settings value, which is stored unsanitized and later unserialized by getValueAttribute() when the setting is read. Attackers can submit a serialized gadget chain, such as one generated via phpggc, through the admin settings form (for example the maintenancemessage setting loaded by CheckMaintenance.php) to achieve arbitrary operating-system command execution as the PHP application process user, with the impact persisting until the value is overwritten.

A stored Cross-Site Scripting (XSS) vulnerability in the file upload functionality of the Media Manager in TastyIgniter v4.3.0, caused by insufficient validation and sanitization of SVG files. An authenticated user with low privileges can upload a malicious SVG file containing JavaScript code. When an administrator views that file, the code executes in the context of their browser. By chaining this vulnerability with a Cross-Site Request Forgery (CSRF) attack, an attacker can extract the administrator’s CSRF token and perform unauthorized actions—such as modifying credentials—thereby gaining full control of the administrative account.

Cross-Site Scripting (XSS) vulnerability exists in TastyIgniter 3.7.7, affecting the /admin/mediamanager component. Attackers can upload a malicious SVG file containing JavaScript code. When an administrator previews the file, the code executes in their browser context, allowing the attacker to perform unauthorized actions such as modifying the admin account credentials.

TastyIgniter 3.7.6 contains an Incorrect Access Control vulnerability in the invoice() function within Orders.php which allows unauthorized users to access and generate invoices due to missing permission checks.

TastyIgniter 3.7.6 contains an Incorrect Access Control vulnerability in the Orders Management System, allowing unauthorized users to update order statuses. The issue occurs in the indexonUpdateStatus() function within Orders.php, which fails to verify if the user has permission to modify an order's status. This flaw can be exploited remotely, leading to unauthorized order manipulation.

TastyIgniter v3.5.0 was discovered to contain a cross-site scripting (XSS) vulnerability which allows attackers to execute arbitrary web scripts or HTML via a crafted payload.

Cross-site Scripting (XSS) - DOM in GitHub repository tastyigniter/tastyigniter prior to 3.3.0.

A Cross-Site Scripting (XSS) vulnerability exists within the 3.2.2 version of TastyIgniter. The "items%5B0%5D%5Bpath%5D" parameter of a request made to /admin/allergens/edit/1 is vulnerable.

TastyIgniter 3.0.7 allows XSS via /account, /reservation, /admin/dashboard, and /admin/systemlogs.
