Weekly Cybersecurity Recap from Hoplon InfoSec

Some weeks feel quiet on the surface, yet the security world keeps moving underneath like a busy subway tunnel. This past week had that feeling. A mix of software flaws, vendor mistakes, airline surprises, and a few uncomfortable truths about user awareness. Here is what stood out and why it matters.
1. Next.js and React RCE Vulnerability
If you work with modern web apps, this one probably made your stomach drop. The React and Next.js maintainers confirmed a serious remote code execution issue that can let an attacker take control of a server with nothing more than a simple crafted request. It sounds dramatic, but it is very real.
The problem shows up in React Server Components and the Next.js App Router. Even a clean project that was created just a few minutes earlier can be exposed if it uses the affected packages. Many developers assumed this feature was safe by default, so the sudden warning felt like someone discovering a hidden crack in the foundation of a brand new house.
The fix is straightforward. Update React to the patched server dom versions and bump your Next.js installation to one of the protected releases. This is one of those situations where delaying the update can turn a minor inconvenience into a disaster.

2. Iberia Data Breach
Iberia, the European airline, confirmed a breach involving one of its suppliers. The attackers walked away with customer names, email addresses and loyalty numbers. The airline insists that passwords and card data were not touched, and so far the investigation supports that claim.
Still, the whole story brings up a problem everyone overlooks. Even reputable brands can be dragged down by a third party that fails to keep its own systems secured. And customers rarely know how many companies are behind the scenes handling their data. If you have an Iberia account, check it. Most people wait until something bad happens before updating an old password. This is one of those moments when it pays to be early rather than late.
3. Asahi Data Leak
Asahi faced a much larger storm. After a ransomware attack disrupted operations, it became clear that more than one and a half million individuals might have had their personal information exposed. Employees, partners, customers and even family members of employees were potentially dragged into the fallout.
Besides the privacy issues, the attack jammed up Asahi’s supply chain. Stores and restaurants that depend on the company’s products reported delays and shortages. It is a reminder that a cyberattack rarely stays inside the walls of the original victim. The damage spreads outward, affecting people who may not even know the company’s name.

4. Americans Rarely Check If They Are in Data Breaches
A new study delivered a harsh but unsurprising number. Roughly sixty four percent of adults in the United States have never checked whether their information has appeared in a breach. Many seem to think that if no one calls them directly to report a leak, they must be fine.
The truth is almost the opposite. Attackers rarely warn their victims. Data can sit quietly in a database on the dark web for years before someone decides to use it. A five minute check and a quick password change could prevent weeks of frustration. Yet most people never bother. This report captured that reality in a single uncomfortable statistic.
5. Microsoft Entra ID CSP Update
Microsoft is preparing a significant update to Entra ID login pages that will go into full effect in 2026. Once enforced, the login experience will only allow scripts that originate from Microsoft owned sources. Anything injected by browser extensions, automation tools or custom environments will be blocked.
This might sound like a minor detail, but it will change how many organizations handle testing, automation and internal workflows. Anyone relying on non standard scripts to carry out login actions will need to rethink their setup. The intention is good. Keeping the login surface cleaner reduces the chance of malicious scripts slipping into the process. It will just take some adjustment for teams that have been bending the login flow to fit their tools.
Key Takeaways
This week reminded me of a simple pattern. Big companies create the technology, attackers find the weak spots, and regular people end up dealing with the consequences. Developers need to patch quickly. Travelers need to stay alert. Everyday users should not assume their data is safe just because no one told them otherwise.
Security is not a one time task. It is a habit. A weekly recap like this is just one small way to stay aware of how fast things can change.
Frequently Asked Questions
1. Do all React or Next.js apps need to update immediately
If the project uses React Server Components or the Next.js App Router, the answer is yes. Those setups are directly affected. If your project is fully client side, the risk is far smaller, but updating is still the safest choice.
2. Should travelers be worried about the Iberia breach
The leak did not include passwords or payments, but loyalty accounts and emails can still be used for targeted phishing. A password change and enabling multi factor authentication is a smart step.
3. Does the Asahi incident affect people outside their customer base
Not directly, but it shows how widespread the damage from ransomware can become. Supply chain disruptions often reach businesses and customers who have no connection to the original victim.
4. Will the Microsoft Entra ID update break existing workflows
It might. Any automation or extension that injects custom scripts into the login page could fail once the new policy is enforced. Teams using those tools should start testing alternatives soon.
