CVE-2026-50193 jackson-databind: Deeply nested JsonNode throws StackOverflowError for toString()

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if and only if the service reads deeply nested 1000s of levels JSON as JsonNode...

CVE-2026-50193

jackson-databind contains a DoS in JSON tree handling: if a service reads deeply nested JSON (1000s of levels) via ObjectMapper.readTree() and then writes that JsonNode with toString(), it can consume significant resources. Affected are 2.13.0–2.14.0; fixed in 2.14.0. Mitigation: upgrade to 2.14....

CVE-2025-71382

MuPDF prior to 1.27.0-rc1 is affected by an uncontrolled recursion in the EPUB CSS rendering engine. The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, enabling remote attackers to trigger a denial of service by...

CVE-2025-71382 MuPDF < 1.27.0-rc1 Stack Exhaustion DoS via EPUB CSS Rendering

MuPDF before 1.27.0-rc1 contains an uncontrolled recursion vulnerability in the EPUB CSS rendering engine that allows remote attackers to cause a denial of service by supplying a maliciously crafted EPUB file with deeply nested HTML elements and inline CSS styles. The function...

PT-2026-51594

Name of the Vulnerable Software and Affected Versions jackson-databind versions 2.13.0 through 2.13.x Description A potential Denial-of-Service exists when a service reads deeply nested JSON thousands of levels as a JsonNode using the readTree function of ObjectMapper and subsequently writes that...

dotnet: ASP.NET Core: Denial of Service via uncontrolled resource consumption

A flaw was found in ASP.NET Core SignalR and Blazor Server. A remote attacker could send a specially crafted MessagePack payload containing deeply nested arrays that trigger excessive recursion and cause a stack overflow. This issue may result in application termination and a denial of service...

RUSTSEC-2026-0187 Stack overflow in lopdf via deeply nested PDF objects

lopdf::Document::loadmem and the other load entry points parses nested PDF arrays and dictionaries with unbounded recursion. A small crafted PDF whose Catalog contains a deeply nested array /X … , on the order of 10,000 levels exhausts the call stack and aborts the process with SIGABRT. Because...

Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through recursive calls to the eachchild function when processing deeply nested input. An attacker can cause the process to crash and trigger a denial of service by supplying a specially crafted, deeply nested JSON...

GHSA-3M6Q-JJ5J-38C9 Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process.

Faraday: Uncontrolled recursion in NestedParamsEncoder allows stack exhaustion DoS via deeply nested query parameters

Faraday::NestedParamsEncoder, the default nested query parameter encoder/decoder in Faraday, decodes nested query strings without enforcing a maximum nesting depth. A crafted query string such as: text axxxx...x=1 causes Faraday to build a deeply nested Ruby Hash structure. The internal dehash...

Oj - Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Impact Reliable denial of service: any endpoint that calls Oj::Doc.openuntrusted |d|...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion during the JSON conversion. An attacker can exhaust the call stack and cause the application to crash by supplying crafted protobuf binary data containing deeply nested Any values that are expanded during...

CVE-2026-5079

Impact: multer versions 1.0.0 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service via deeply nested field names in multipart form data. The append-field dependency parses bracket notation in field names with no limit on nesting depth, allowing an attacker to force allocation of...

CVE-2026-5079

The CVE-2026-5079 issue affects the Multer library (versions 1.0.0–2.1.1 and 3.0.0-alpha.1). The vulnerability arises from the append-field dependency parsing bracket notation in field names with no limit on nesting depth, which can cause the allocation of deeply nested object structures and cons...

UBUNTU-CVE-2026-44250

Netty is a network application framework for development of protocol servers and clients. In netty-codec-redis prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can cause DoS by sending a crafted Redis payload with deeply nested arrays. This forces the server to allocate a massive...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception through the link validation. An attacker can cause the application to crash or become unresponsive by submitting deeply nested input that triggers an unhandled RangeError exception. This is only exploitable if input...
