Echo Mirage 3.1 Stack Buffer Overflow via Rules Action Field

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Echo Mirage 3.1 contains a stack buffer overflow vulnerability that allows local attackers to crash the application or execute arbitrary code by supplying an oversized string in the Rules action field. Attackers can create a malicious text file with a crafted payload exceeding buffer boundaries and paste it into the action field through the Rules dialog to trigger the overflow and overwrite the return address.
