CRITICAL LANGFLOW FLAWS COULD LET UNAUTHENTICATED ATTACKERS RUN CODE ON SERVERS

IBM reported four Langflow vulnerabilities affecting versions 1.0.0 through 1.12.8. Two are critical and require no account: CVE-2026-93680 bypasses authentication, while CVE-2026-110186 permits arbitrary code execution through MCP tool enumeration. A public Metasploit module already enumerates Langflow MCP tools without credentials. Version 1.13.0 is the only fix. It disables automatic login by default. IBM has not published a workaround.

SPACEX IS REPORTEDLY LOOKING AT BUYING BOOST MOBILE OR USING ITS CELL NETWORK

SpaceX has held talks with EchoStar to potentially acquire Boost Mobile outright or gain access to its cell network, which is leased from AT&T and T-Mobile. Starlink recently confirmed plans to become a major mobile carrier in the US. The deal will need approval from AT&T and T-Mobile, both of which have already turned down SpaceX for access to their cell towers. SpaceX last year acquired $2.6 billion worth of spectrum licenses from EchoStar to improve its Starlink network's 5G connections.

HOW WE HALVED DNS BUILD DELAY AND CUT MEMORY USE BY 85%

Cloudflare replaced full DNS zone rebuilds with a planner that selects the smallest provably safe update and a scheduler that combines work for the same zone. The changes cut peak memory by 85% and halved the delay from a DNS change to its data being written to Quicksilver without rebuilding tens of millions of records for a settings change.

GOOGLE SAYS AI CHATBOTS ARE HURTING ITS BOTTOM LINE

Google's AI search features are putting pressure on its core advertising business. Search volume growth slowed from 19% in Q1 to 12% in Q3 while search revenue remained flat. Google says AI Mode queries generate less ad revenue and plans to expand ads across AI Overviews and AI Mode to offset the impact. As more users turn to chatbots for answers, Google faces a challenge in maintaining ad revenue while investing in increasingly costly AI features.

The landings will involve a lunar-orbit rendezvous similar to what NASA did with the Apollo program. China and the US are racing to land astronauts on the lunar surface, as it would be a major geopolitical win. Both countries are also building capabilities to establish a long-term presence at the Moon's South Pole.
