Title
Vvveb: Vvveb CMS — Negative-quantity cart manipulation allows creation of orders with negative grand totals
Summary
Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.2, Vvveb CMS does not validate the sign of the quantity parameter on the cart-add endpoint. Submitting a negative integer is accepted by the server and treated as a normal positive line-item, but with the sign carried through into every downstream computation: line total, sub-total, taxes, and grand total all become negative numbers. The customer-facing cart UI then displays a negative grand total to the user, the checkout flow accepts the negative cart, and the resulting order is persisted in the merchant's database with a negative total column. From the merchant's order management dashboard, this surfaces as a real order with a negative total — an "the merchant owes the customer money" record that no legitimate workflow ever creates. This vulnerability is fixed in 1.0.8.2.

CVE-2026-9704 (GCVE-0-2026-9704)

Vulnerability from cvelistv5 – Published: 2026-05-27 12:56 – Updated: 2026-06-10 21:21
VLAI
Title
Keycloak: keycloak: privilege escalation due to oversized subject_token jwt
Summary
A flaw was found in Keycloak. An authenticated user with low privileges can exploit this vulnerability by sending an oversized subject_token JSON Web Token (JWT) to the TokenEndpoint. When the token exceeds a 4000-character limit, it is silently dropped, causing the system to fall back to client credentials. This allows the user to gain the permissions of the client's service account, leading to privilege escalation.

Mitigation ID: MIT-5

Phase: Implementation

Strategy: Input Validation

Description:

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
