Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the Parser and AsyncParser recursive JSON parsing paths in parser/shared/src/main/scala/jawn/Parser.scala and parser/shared/src/main/scala/jawn/AsyncParser.scala. An attacker...

CVE-2026-59168

Dasel is a command-line tool and library for querying, modifying, and transforming data structures. From 3.0.0 until 3.11.1, parsing/json/jsonreader.go decodeValue, decodeObject, and decodeArray, and parsing/xml/reader.go parseElement, recurse once per input nesting level without a depth guard...

CVE-2026-61551

Icinga 2 is an open source monitoring system. Prior to 2.14.9, 2.15.4, and 2.16.2, parsing deeply nested JSON can exhaust the call stack because nesting depth is not bounded. The affected JSON parsing paths are reachable by unauthenticated network clients through the Icinga 2 service on TCP port...

CVE-2026-61551

Icinga 2 , an open source monitoring system, is affected by a stack overflow in its JSON parsing paths prior to versions 2.14.9 , 2.15.4 , and 2.16.2 . The root cause is that nesting depth is not bounded, so deeply nested JSON objects exhaust the call stack. The vulnerable paths are reachable by ...

CVE-2026-61551 Icinga 2: Stack overflow via deeply nested JSON objects

Icinga 2 is an open source monitoring system. Prior to 2.14.9, 2.15.4, and 2.16.2, parsing deeply nested JSON can exhaust the call stack because nesting depth is not bounded. The affected JSON parsing paths are reachable by unauthenticated network clients through the Icinga 2 service on TCP port...

CVE-2026-68914 Mojolicious pure-Perl Mojo::JSON decoder allows memory exhaustion via deeply nested data

Mojolicious is a real-time web framework for Perl. Prior to 9.47, the pure-Perl implementation of Mojo::JSON does not limit nesting depth when Cpanel::JSON::XS is unavailable or MOJONOJSONXS is enabled. An attacker who can supply untrusted JSON to decodejson, fromjson, or j can submit deeply nest...

The ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.5.5 via deserialization of untrusted input . This makes it possible for authenticated attackers, with author-level access and...

CVE-2026-61551: Uncontrolled Recursion

Icinga 2 is an open source monitoring system. Prior to 2.14.9, 2.15.4, and 2.16.2, parsing deeply nested JSON can exhaust the call stack because nesting depth is not bounded. The affected JSON parsing paths are reachable by unauthenticated network clients through the Icinga 2 service on TCP port...

CVE-2026-93450 go-openapi/swag jsonutils before 0.27.1 Uncontrolled Recursion in Ordered JSON Marshal and Unmarshal

go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing...

aws-smithy-json: aws-smithy-json: Denial of Service via uncontrolled recursion with deeply nested JSON

A flaw was found in aws-smithy-json. This vulnerability allows a remote, unauthenticated attacker to cause a denial of service DoS in smithy-rs generated servers. By sending a small HTTP request containing deeply nested JSON, the attacker can trigger uncontrolled recursion in the aws-smithy-json...
