What it is

Why it matters
This is a critical flaw with a severe impact, scoring 9.9 out of 10, because it directly leads to full server control. The urgency is heightened as this vulnerability is actively being used in known ransomware campaigns. This means systems running SimpleHelp are at immediate risk of compromise.
