CVE-2026-67552

A flaw was found in Apache Qpid Proton-Dotnet. This vulnerability allows a remote attacker, without needing to authenticate, to exploit a weakness in how the software handles data structures with excessive nesting. This can lead to a StackOverflowError, which ultimately results in a denial of...

CVE-2026-13506

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit a vulnerability related to how the software processes lazy ASN.1 sequences, which can reset an internal nesting-depth guard. This issue could lead to a Denial of Service DoS, making the affected system or application...

Astra Linux – Vulnerability in expat

In Expat also known as libexpat, before version 2.4.5, an attacker could trigger stack exhaustion in buildmodel by using a large nesting depth in the DTD element...

Astra Linux – Vulnerability in json-smart

Json-smart is a performance-oriented JSON processor library. When encountering a ‘’ or ‘’ character in the JSON input, the code parses an array or an object respectively. It was discovered that the code does not have any limitations regarding the nesting of such arrays or objects. Since the parsi...

Astra Linux – Vulnerability in LibreOffice

LibreOffice Calc compiles cell formulas when opening a spreadsheet. A heap buffer overflow occurred when compiling a very long formula consisting of many opening tokens. The array that tracks nesting depth was allocated with one element too small in the worst-case scenario; as a result, such a...

Astra Linux – Vulnerability in libxml-parser-perl

XML::Parser versions up to 2.47 for Perl have a heap buffer overflow issue in stserialstack. In the case where stackptr == stacksize - 1, the stack will NOT be expanded. As a result, the new value will be written at location ++stackptr, which equals stacksize. This means that the new value falls...

CVE-2026-74039

Wazuh 4.0.0 before 4.14.7 and 5.0.0-beta2 contain a denial of service vulnerability that allows authenticated attackers with allowrunas enabled to exhaust CPU resources by submitting arbitrarily deeply nested JSON structures to the POST /security/user/authenticate/runas endpoint. Attackers can...

CVE-2026-69220 RabbitMQ Java client ValueReader: Unbounded recursive table/array nesting causes StackOverflowError DoS

CVE-2026-74783

Scriban versions 6.6.0 through 7.2.0 contain a non-enforcing ExpressionDepthLimit guard that fails to stop recursive descent parsing of deeply nested expressions. Attackers can supply templates with deeply nested parentheses, array initializers, object initializers, or unary operators to trigger ...

encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

CVE-2026-62295

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the JSON utility parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth for arrays or objects. As a result, a small but deeply nested,...

CVE-2026-62296

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner and parseElement, raisi...
