{"id":"BIT-postgis-2026-73515","summary":"PostGIS \u003c 3.7.0 Out-of-Bounds Read via FlatGeobuf Buffer","details":"PostGIS before 3.7.0 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.","aliases":["CVE-2026-73515"],"modified":"2026-09-25T15:45:03.182257550Z","published":"2026-09-25T15:20:21.187Z","database_specific":{"cpes":["cpe:2.3:a:postgis:postgis:*:*:*:*:*:postgresql:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://gitea.osgeo.org/postgis/postgis/raw/tag/3.7.0beta2/NEWS"},{"type":"WEB","url":"https://mehmetince.net/part-1-6-systemic-risks-in-the-managed-postgresql-industry-extension-risks-are-real-exploiting-postgis-memory-corruption-bug-at-neondb-supabase-and-many-more/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73515"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/postgis-0beta2-out-of-bounds-read-via-flatgeobuf-buffer"}],"affected":[{"package":{"name":"postgis","ecosystem":"Bitnami","purl":"pkg:bitnami/postgis"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.7.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/postgis/BIT-postgis-2026-73515.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
