Technical description

geojson-vt is a JavaScript library for slicing GeoJSON data into vector tiles on the fly, primarily designed to enable rendering and interacting with large geospatial datasets on the browser side (without a server). Prior to version 6.1.1, @maplibre/geojson-vt contains an uncontrolled recursion vulnerability in its GeoJSON conversion logic. When a GeoJSONVT instance is constructed with a deeply nested GeometryCollection object, the mutually recursive functions featureToInternal and convertGeometryCollection in src/convert.ts exhaust the Node.js call stack, causing an unhandled RangeError: Maximum call stack size exceeded that terminates the process. Because the library is widely used in server-side tile services that accept GeoJSON over the network, a remote unauthenticated attacker can trigger a denial-of-service by sending a single crafted payload. No authentication is required, and no non-default library options are needed. This issue has been patched in version 6.1.1.

——9In Eclipse Kura versions 5.4.0 through 5.6.2, the Service Listing V1 REST API read the JSON body of every request into memory, with no limit on its size. The endpoints parse the body before they check whether the caller is authenticated. A remote attacker without valid credentials can therefore send a few dozen large JSON requests at the same time, exhaust the Java heap with an `OutOfMemoryError`, and cause a denial of service. Likewise, a remote attacker, can send a deeply nested JSON request and trigger a `StackOverflowError` because of an unbound recursion in Service Listing V1.1d CVE-2026-1252215.5 MED

——2FFmpeg through 9.0.2 contains an uncontrolled recursion vulnerability in score_header() in libavcodec/flac_parser.c that allows attackers to exhaust the thread stack via crafted FLAC input. Attackers can supply a FLAC stream packed with many small valid-looking frame headers, forcing deep recursion that crashes the process during demuxing or parsing.1d
