SHA1 vulnerable
As computers evolve its becoming aier to break into aglorithms.It appears that upgrading the algorithm to SHA2 and SHA3 be the rigt way to go ahed.As quantum computers evolve it is just a  matter of time when algorithms like SHA2 and SHA 3 can also be broken.

The 10 Most Impactful Types of Vulnerabilities for Enterprises Today
Managing system vulnerabilities is one of the old est - and most frustrating - security challenges that enterprise defenders face. Every software application and hardware device ships with intrinsic flaws - flaws that, if critical enough, attackers can exploit from anywhere in the world. It's crucial that defenders take stock of what areas of the tech stack have the most emerging, and critical, vulnerabilities they must manage. It's not just zero day vulnerabilities. Consider that CISA's Known Exploited Vulnerabilities (KEV) catalog lists vulnerabilitlies in widely used applications that are "actively exploited," and most of them are flaws that were discovered several years ago and have been fixed. There are also emerging vulnerabilities in 5G networks, cloud infrastructure, Edge applications, and firmwares to consider.
