A serious security vulnerability affecting PHP, the programming language used by many websites and online services, prompted emergency action across government yesterday.
The National Cyber Security Centre warned organisations to apply security updates immediately.
The UK Government confirmed that 32 government services had been taken offline as a precaution.
NCSC officials said there was no indication that the vulnerability had been successfully exploited by attackers.
Why it matters for Wales: The vulnerability potentially affects websites operated by Welsh councils, public bodies, schools, businesses and voluntary organisations.
It also highlights the importance of maintaining public-sector digital infrastructure and ensuring that older software receives timely security updates.
Status: Confirmed critical vulnerability and precautionary service disruption. No successful exploitation or Wales-specific breach has been established.
