CVE-2026-73515
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk34th percentile - higher than 34% of all known CVEs
Summary
PostGIS before 3.7.0beta2 contains an out-of-bounds read vulnerability that allows attackers to cause memory disclosure or a server crash by supplying a malformed FlatGeobuf buffer. The FlatGeobuf property metadata decoder verifies that a string length field is present but fails to verify that the subsequent string body is contained within the supplied buffer before materializing it into a SQL-visible value, enabling memory disclosure or denial of service.
Risk Assessment
Risk of sensitive data leakage from server memory and disruption of database services.
Recommendation
Update PostGIS to version 3.7.0beta2 or later, which includes the fix.
