nodejs: Node.js: Heap-use-after-free in HTTP/2 handling can lead to denial of service
A heap use-after-free vulnerability in the Node.js HTTP/2 component allows a remote attacker to crash the application, causing a denial of service. This is triggered by an unexpected re-entrant call to nghttp2sessionmemsend while nghttp2sessionmemrecv is still executing...
brace-expansion: Brace-expansion: Denial of Service via memory exhaustion in expand() function
A flaw was found in brace-expansion. A remote attacker can exploit this vulnerability by providing specially crafted input to the expand function, which can lead to excessive memory consumption. This can cause a denial of service DoS by crashing the application due to an out-of-memory error...
ip-address: ip-address: Inconsistent IP address parsing leads to Server-Side Request Forgery (SSRF) and trust-boundary bypass
A flaw was found in the ip-address library. This library incorrectly interprets IPv4 address octets with leading zeros as decimal, while standard network parsers interpret them as octal. This inconsistency can cause applications to misclassify network targets, allowing a remote attacker to bypass...
brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation
A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...
nodejs: Node.js: Unauthorized filesystem access due to Permission Model enforcement flaw
A flaw in the Node.js Permission Model allows attackers to bypass --permission restrictions, enabling unauthorized read or write access to files and directories...
nodejs: Node.js: Remote memory exhaustion via HTTP/2 retained header blocks
A flaw was found in Node.js's handling of HTTP/2. This vulnerability allows a remote attacker to bypass maxSessionMemory limits by sending specially crafted HTTP/2 retained header blocks. This can lead to memory exhaustion, resulting in a denial of service DoS for the affected system...
python-cryptography: python-cryptography: Duplicate self-signed intermediates can cause exponential path-building
A flaw was found in python-cryptography. When processing invalid certificate chains that include duplicate self-signed certificates, the system recursively invokes the same certificate, leading to an exponential increase in processing time. A remote attacker could exploit this by providing a...
python-cryptography: python-cryptography: python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees
A flaw was found in python-cryptography. This vulnerability arises from incorrect handling of wildcard Domain Name System DNS names during certificate validation. Specifically, the verifier may accept a certificate with a broad wildcard DNS name e.g., .example.com even when a more restrictive nam...
389-ds-base: 389-ds-base: pre-authentication NULL pointer dereference via paged results and USE_ONE_BACKEND control in op_shared_search
A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of opsharedsearch allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USEONEBACKEND control, resulting in denial of servic...
389-ds-base: 389-ds-base: heap buffer overflow via SASL wrapped-record length lower-bound underflow in sasl_io_start_packet()
A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...
389-ds-base: 389-ds-base: SASL PLAIN authentication allows privilege escalation to Directory Manager via stale identity in Cyrus SASL auxiliary property
A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes...
389-ds-base: 389-ds: anonymous LDAP client can defeat SELFDN ACI bind-rule checks via empty bind DN
A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated...
crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages
A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...
net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution
A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...
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...
python: cpython: CPython: tarfile extraction filter bypass allows escaping the destination directory
A flaw was found in the tarfile.extractall function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside th...

A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes...
