CVE-2026-71429 stream-json: pick/ignore/filter/replace filters are O(depth²) on nested input — small crafted JSON blocks the event loop for seconds→minutes (DoS)

stream-json is a micro-library of stream components for processing JSON and JSONC with a minimal memory footprint. Prior to 3.5.0, the path filters pick, ignore, filter, and replace in src/core/filters/filter-base.js recompute the full path string from the nesting stack for every checkable token...

CVE-2026-84968 Heap out-of-bounds read via corrupt nested BSON in field path error message

An out-of-bounds read in the BSON decoding component of the MongoDB PHP driver may allow an unauthenticated party who supplies specially formed input to have a small amount of adjacent process memory copied into an error message that is returned to application code. This may result in unintended...

CVE-2026-84646

A flaw was found in Jenkins. An attacker with Overall/Read permission can exploit a deserialization vulnerability where user objects can appear as nested field values in other deserialized XML objects. By submitting crafted XML, the attacker can create unauthorized user objects. While these creat...

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reject oversized nested action attrs Open vSwitch stores generated flow actions as nlattrs, where the nlalen field is of type u16. The vulnerability identified as commit a1e64addf3ff "net: openvswitch: remove...

The vulnerability of the nested_vmcb02_prepare_control() function in the arch/x86/kvm/svm/nested.c module of the virtualization subsystem on the x86 kernel of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the nestedvmcb02preparecontrol function in the arch/x86/kvm/svm/nested.c module of the virtualization subsystem on the x86 kernel of the Linux operating system is related to the incorrect implementation of the sequence of actions to be performed. Exploiting this vulnerability...

CVE-2026-84645

In Jenkins versions weekly ≤ 2.579 and LTS ≤ 2.568.2 , a deserialization vulnerability (SECURITY-3972) allows for remote code execution (RCE) . The root cause lies in the XStream stack (hudson.util.XStream2 / RobustReflectionConverter), where PersistenceRoot types can be deserialized as nested fi...

GHSA-6M44-FPC8-C3RQ Mistune: Denial of Service — RecursionError via Excessive Emphasis Markers in Markdown

Summary Mistune v3.3.2 is vulnerable to a Denial of Service DoS attack via uncontrolled recursion in the HTML rendering of deeply-nested emphasis tokens. By submitting Markdown containing approximately 1,000 consecutive asterisk characters, an attacker causes the Python process to crash with...

NLTK: Uncontrolled recursion in nltk.featstruct.FeatStructReader causes unhandled RecursionError (DoS) via deeply nested feature-structure input

Summary nltk.featstruct.FeatStructReader used by FeatStructstr and by FeatureGrammar.fromstring parses feature-structure strings such as a=1 with a recursive-descent parser that has no nesting-depth limit. A small, trivially-crafted input 700 bytes with deeply nested brackets drives the parser pa...

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...
