TechnologyInternationalEl Ecosistema StartupNov 14, 2026, 2:03 PMAI summary

Vercel Labs released UI SDK, an open beta library with more than 50 interface behaviors that coding agents assemble to build accessible components. The six packages on npm are at version 0.1.0-beta.1 under the Apache-2.0 license and run on React 19+, Vue 3.5+, Svelte 5.33+, Solid 2.0.0-rc.14+ and Web Components. It includes createAgent(), which exposes to agents which components exist, their state and the executable actions through snapshot() and act().

UI SDK provides primitives such as popup, selection and typeahead that the agent combines, rather than a catalog of components to copy.
The @ui-sdk/core core defines primitives with definePrimitive and each adapter renders them with createParts across five frameworks.
createAgent() lets an agent query state with snapshot() and run actions with act(), with an allow callback to accept or reject each action.

ESET: unpatched systems and public passwords enabled attacks on supermarket refrigerators
Cyberattacks that affected supermarket refrigeration systems in nine European countries, starting in France, exposed the risks of connecting devices to the internet without adequate protection. Rodrigo Álvarez, a specialist at ESET Latin America, said on Blu Radio that the incidents were possible due to vulnerabilities in the refrigerators' remote control systems, a lack of security patch updates and publicly exposed access passwords. The damage caused temperature increases in the equipment. The expert pointed to the responsibility of companies' technology departments.

Agentic commerce: 72% in Brazil would buy with AI, but only 21% would let it complete the payment
Global Payments' Agentic Commerce Report 2026 finds that 72% of consumers in Brazil would be willing to buy through artificial intelligence agents, up from 39% in 2025. Trust drops at the payment stage: only 21% would allow a purchase to be completed without human intervention and 59% would prefer to approve each transaction. 52% identify payment protection as their main concern. For Colombia, the model poses challenges in digital security, data protection and consumer rights.

Italy fines Meta $887 million for accessing Android data without consent
Italy's Data Protection Authority fined Meta Platforms Ireland Limited $887 million for accessing, through the Facebook app on Android, photos, videos and metadata from about 20 million users without specific consent. The penalty equals roughly 0.47% of the group's global revenue and stems from the "get gallery suggestions while browsing Facebook" feature, available since 2023. The regulator found the app requested a single generic permission, enabled by default, that also allowed those suggestions.

US expects up to 5,000 flights canceled this Saturday after ground stop
The FAA estimates that between 4,000 and 5,000 of the 41,000 flights scheduled in the US will be canceled this Saturday, following Friday's nationwide ground stop caused by failures in the agency's telecommunications system. As of local noon, 4,272 cancellations and 3,752 delays had been recorded, according to FlightAware. Transportation Secretary Sean Duffy ruled out a cyberattack and denied any link to the new artificial intelligence system; the problem arose while replacing copper wiring with fiber optics.
