{"apiVersion":"1.0","identifier":"CVE-2026-50126","description":"Adaguc-server is an open source geographical information system to visualize, combine, compare and share real-time meteorological, climatological and remote sensing data via OGC standards. Versions prior to 7.2.2 crash with a memory-safety fault when it parses a GeoJSON document whose geometry contains a malformed coordinate. The coordinate parser in `adagucserverEC/CConvertGeoJSON.cpp` indexes `pt.u.array.values[0]` and `pt.u.array.values[1]` and uses `polygon.u.array.length` as a loop bound without first validating the JSON node type or the coordinate length. A coordinate that is an empty array, a one-element array, a scalar, or `null` leads to an out-of-bounds heap read or a NULL pointer dereference. The same unchecked pattern is present in four geometry branches: `Polygon`, `LineString`, `MultiLineString` and `MultiPolygon`. The vulnerable parser runs whenever the server processes a local GeoJSON file, either a configured GeoJSON dataset or a GeoJSON file exposed through the `AutoResource` feature and requested by an unauthenticated WMS request. A crafted GeoJSON file reliably crashes the backend process that handles that request. Version 7.2.2 patches the vulnerability.","publishedAt":"2026-08-18T17:16:58","lastModifiedAt":"2026-08-18T18:17:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-50126","cvssScore":4,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","epssProbability":0.00124,"riskScore":0.4,"affectedProduct":"adaguc-server","affectedVersions":"<7.2.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-50126","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-50126","en":"https://www.redsauce.net/en/cves/CVE-2026-50126","fr":"https://www.redsauce.net/fr/cves/CVE-2026-50126","pt":"https://www.redsauce.net/pt/cves/CVE-2026-50126","de":"https://www.redsauce.net/de/cves/CVE-2026-50126","sk":"https://www.redsauce.net/sk/cves/CVE-2026-50126","el":"https://www.redsauce.net/el/cves/CVE-2026-50126"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-50126"}}
