CVE-2026-15584

A privilege escalation vulnerability was found in the incluster-checks tool for OpenShift. The tool creates privileged debug pods with host filesystem access in the shared default namespace, where any user with the standard edit role can exec into them and obtain root access on cluster nodes...

CVE-2026-15584: Execution with Unnecessary Privileges

A privilege escalation vulnerability was found in the incluster-checks tool for OpenShift. The tool creates privileged debug pods with host filesystem access in the shared default namespace, where any user with the standard edit role can exec into them and obtain root access on cluster nodes...

Execution with Unnecessary Privileges

Overview Affected versions of this package are vulnerable to Execution with Unnecessary Privileges via the Environment Runtime.Container and Builder.Container processes. An attacker can gain elevated privileges and execute arbitrary code with high-level access by creating or updating environments...

CVE-2026-50566 Fission: Environment Runtime.Container and Builder.Container SecurityContext bypass allows privileged pod creation

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.24.0, a tenant with environments.fission.io create/update RBAC can run privileged / allowPrivilegeEscalation / dangerous-capability...

CVE-2026-33590

Insecure default settings of Portainer CE grant regular non-admin users privileges that allow host filesystem access and host-level code execution. An authenticated non-administrative user with endpoint access can exploit these settings to read host files or obtain root equivalent access on the...

CVE-2026-49238 SFTP Server VM Escape in Canonical Multipass

An issue was discovered in Canonical Multipass before version 1.16.3. The host-side SFTP server component sshfsserver, which executes with root privileges on the host, contains a path containment bypass vulnerability within its validatepath function in src/sshfsmount/sftpserver.cpp. The function...

CVE-2026-33590: Incorrect Default Permissions

Insecure default settings of Portainer CE grant regular non-admin users privileges that allow host filesystem access and host-level code execution. An authenticated non-administrative user with endpoint access can exploit these settings to read host files or obtain root equivalent access on the...

Kata Containers have VM Escape via virtiofsd Argument Injection through Default-Enabled Pod Annotations

Summary Kata Containers ships with a default configuration that allows pod creators to inject arbitrary command-line arguments into the virtiofsd process through the io.katacontainers.config.hypervisor.virtiofsextraargs pod annotation. By injecting -o source=/ along with --no-announce-submounts a...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the fileName parameter during a file upload operation. An attacker can bypass intended storage boundaries and write arbitrary files to any location on the host filesystem accessible by the Java process by supplyi...

zrok: WebDAV drive backend follows symlinks outside DriveRoot, enabling host filesystem read/write

Summary The zrok WebDAV drive backend davServer.Dir restricts path traversal through lexical normalization but does not prevent symlink following. When a symbolic link inside the shared DriveRoot points to a location outside that root, remote WebDAV consumers can read files and—on shares without...

Paperclip: Arbitrary File Read via Agent-Controlled adapterConfig.instructionsFilePath

Summary Paperclip contains an arbitrary file read vulnerability that allows an attacker with an Agent API key to read files from the Paperclip server host filesystem. The vulnerability occurs because agents are allowed to modify their own adapterConfig through the /agents/:id API endpoint. The...

CVE-2025-15547

By default, jailed processes cannot mount filesystems, including nullfs4. However, the allow.mount.nullfs option enables mounting nullfs filesystems, subject to privilege checks. If a privileged user within a jail is able to nullfs-mount directories, a limitation of the kernel's path lookup logic...

CVE-2025-15547 Jail escape by a privileged user via nullfs

By default, jailed processes cannot mount filesystems, including nullfs4. However, the allow.mount.nullfs option enables mounting nullfs filesystems, subject to privilege checks. If a privileged user within a jail is able to nullfs-mount directories, a limitation of the kernel's path lookup logic...

CVE-2025-15547

The CVE-2025-15547 vulnerability affects FreeBSD jail environments configured with the allow.mount.nullfs option. A privileged user inside a jail can mount nullfs directories, and a kernel path-lookup limitation can let the user escape the jail via chroot, granting access to the host/parent files...
