9.8 criticalEPSS 20%

Critical (9.8). EPSS 20% chance of exploitation in the next 30 days.

An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.
