NamelessMC: Reactions on private or blocking profile posts can be read and modified without proper authorization

NamelessMC is website software for Minecraft servers. In version 2.2.4,`core/classes/Misc/ProfilePostReactionContext.php` only verifies that the wall post exists and does not enforce blocked/private-profile visibility. `modules/Core/queries/reactions.php` allows unauthenticated GET requests for reaction details. This means that unauthenticated visitors can read reaction participants and timestamps for private profile posts and uthenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 fixes the issue.

NamelessMC: Forum reactions bypass the "view own topics only" restriction

NamelessMC is website software for Minecraft servers. In version 2.2.4, `modules/Forum/classes/ForumPostReactionContext.php` only verifies that the caller can view the forum, but it does not re-enforce topic-level `view_other_topics` authorization. As a result, in forums where users may enter the forum but may only view their own topics, reactions can still be read and modified on other users' topics. Version 2.2.5 fixes the issue.

Sylius is Missing Authorization in API v2 Add Item Endpoint

Sylius is an Open Source eCommerce Framework on Symfony. The POST /api/v2/shop/orders/{tokenValue}/items endpoint does not verify cart ownership. An unauthenticated attacker can add items to other registered customers' carts by knowing the cart tokenValue. An attacker who obtains a cart tokenValue can add arbitrary items to another customer's cart. The endpoint returns the full cart representation in the response (HTTP 201). The issue is fixed in versions: 2.0.16, 2.1.12, 2.2.3 and above.
