Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2, under certain circumstances, attackers can exploit a flaw in domain name normalization to spoof domains they do not own. Versions 3.5.14, 4.0.10, 4.1.8, and 4.2.0-rc2 contain a patch for this issue.

Mastodon 4.1.x before 4.1.17 and 4.2.x before 4.2.9 allows a bypass of rate limiting via a crafted HTTP request header.

A security vulnerability has been detected in Bdtask/CodeCanyon Isshue Multi Store eCommerce Shopping Cart Solution 5. Affected by this issue is some unknown functionality of the file /submit_checkout. Such manipulation of the argument order_total_amount/cart_total_amount leads to enforcement of behavioral workflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0 in the add-sales.php file. The application fails to verify if the requested sales quantity (txtqty) exceeds the available stock level. An attacker can manipulate the request to purchase a quantity that is significantly higher than the actual available stock.

A loop hole in the payment logic of Sparkshop v1.16 allows attackers to arbitrarily modify the number of products.

Controls limiting uploads to certain file extensions may be bypassed. This could allow an attacker to intercept the initial file upload page response and modify the associated code. This modified code can be forwarded and used by a script loaded later in the sequence, allowing for arbitrary file upload into a location where PHP scripts may be executed.
