CVE-2026-42784

A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an...

CVE-2026-85731

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, content/file.Store extraction of OCI layers marked with io.deis.oras.content.unpack=true can write outside the store working directory. The pushDir path through extractTarDirectory and ensureLinkPath validates symlink targets...

CVE-2026-85732

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, the parseLink function in registry/remote/utils.go accepts an absolute URL from a registry-controlled Link response header without validating its scheme, host, or port. Tags, Referrers, and Repositories pagination operations then...

Origin validation error in .NET allows an unauthorized attacker to disclose information over a network...

dotnet10.0: dotnet9.0: .NET Elevation of Privilege Vulnerability

Exposure of sensitive information to an unauthorized actor in .NET allows an authorized attacker to elevate privileges locally...

CVE-2026-19607

A flaw was found in the first-broker-login flow of the keycloak-services component. This component handles the initial authentication and account linking when a user logs in via an external identity provider. The issue allows an attacker to register a matching username on an external provider to...

CVE-2026-92627

A heap-use-after-free vulnerability exists in H5Tconvff in src/H5Tconv.c in HDF5 before 1.14.2. When converting a compound datatype containing floating-point members during a dataset read, a temporary buffer allocated with calloc is freed and subsequently read from within the same conversion...

CVE-2026-59944

Composer is a dependency Manager for the PHP language. From 1.0 until 2.2.30 and from 2.3.0 until 2.10.3, a malicious or compromised dependency can bypass the earlier CVE-2026-59946 binary-path hardening because Composer validates literal parent-directory segments only during dependency resolutio...

python: Python: Privilege escalation due to insecure VPATH handling in Windows legacy installers

A flaw was found in Python. On Windows systems utilizing legacy installers, a low-privilege user can exploit insecure handling of the VPATH variable. This allows the user to create a specific landmark file outside the Python installation directory. Consequently, an alternative Lib folder can be...

python: Python: FTP connection redirection via ftpcp() function bypass

A flaw was found in the ftplib.py module of Python. This vulnerability allows a remote attacker to bypass a previous security fix by manipulating the ftpcp function. By supplying a malicious IP address and port, an attacker can redirect FTP connections to an arbitrary host. This could lead to the...

python: Python: Denial of Service via out-of-bounds write in BZ2 decompression

A flaw was found in Python's bz2.BZ2Decompressor component. An attacker could provide specially crafted input that, when processed by an application reusing a decompressor object after an error, could lead to out-of-bounds writes in memory. This memory corruption could cause the application to...

python: Python tarfile module: File modification and content disclosure via crafted archives

A flaw was found in Python's tarfile module. This module's data and tar extraction filters are vulnerable to specially crafted archives containing a hard link to a symbolic link. An attacker could exploit this by providing a malicious archive. This could lead to unauthorized modification of file...

python: Python/Expat: Denial of Service via crafted XML document

A flaw was found in the python and expat components. Insufficient entropy in the hash-flooding protection mechanism of xml.parsers.expat and xml.etree.ElementTree allows a remote attacker to craft a malicious XML document. This crafted document can trigger a hash flooding attack, leading to a...

python: Python unicodedata: Denial of Service due to excessive CPU consumption

A flaw was found in the unicodedata.normalize function in Python. This vulnerability allows a remote attacker to cause excessive CPU consumption by providing specially crafted Unicode input. Successful exploitation can lead to a Denial of Service DoS on the affected system...

keycloak-services: keycloak-services: SAML Redirect DEFLATE helpers leak native zlib state

A flaw was found in the SAML Redirect Binding implementation of Keycloak, an open-source identity and access management solution. The issue occurs because the custom DEFLATE compression and decompression helpers fail to release native zlib memory after use. An unauthenticated attacker can exploit...

keycloak-services: keycloak-services: Incomplete fix for arbitrary filesystem path probing via keystore parameters

A flaw was found in the key provider component of the keycloak-services library, which is the core engine for the Red Hat Build of Keycloak. The issue occurs because a previous fix for path probing was incomplete, allowing a realm administrator to still submit arbitrary filesystem paths as keysto...

keycloak-services: keycloak-services: unauthenticated DoS via unbounded locale caching

A flaw was found in the theme localization endpoints of the keycloak-services component, which is the core service responsible for authentication flows and theme management in Keycloak. The issue occurs because the system accepts arbitrary locale tags from unauthenticated requests and stores them...
