Multiple vulnerabilities, including CVE-2026-2399, CVE-2026-2404, CVE-2026-2405, CVE-2026-2403, CVE-2026-2400, and CVE-2026-2401, in Schneider Electric PowerChute Serial Shutdown versions 1.4 and prior could allow attackers with adjacent network access and high privileges to overwrite critical system files via path traversal, forge or inject malicious log data, gain unauthorized account access through excessive authentication attempts, trigger denial-of-service conditions, or expose sensitive information.

A vulnerability in Fleet's agent-side deployer (CVE-2026-44938) allows an attacker with `git push` access to a Fleet-monitored repository to overwrite Pod Security Standards (PSS) enforcement labels on target Kubernetes namespaces, bypassing admission controls and enabling the deployment of otherwise prohibited workloads.

An unauthenticated regex injection vulnerability exists in Rancher Fleet's webhook endpoint when it's configured without a secret, allowing attackers to forge webhook requests using unsanitized repository URL components, which leads to continuous repository re-cloning, causing network and resource exhaustion (Denial of Service) on the management cluster, and potentially service downgrades if the attacker has read access to the target Git repository.

A critical privilege escalation vulnerability exists in Rancher Manager where a Project Owner can modify Pod Security Admission (PSA) labels on namespaces within their projects, allowing them to configure a namespace to use the privileged profile, which enables the deployment of privileged workloads that bypass standard container isolation, leading to host-level access and cluster privilege escalation.

The CIFSwitch vulnerability in the Linux kernel allows an unprivileged user to forge CIFS authentication key descriptions, abuse the kernel's key request mechanism, and gain root privileges by loading a malicious NSS module.

A remote, anonymous attacker can exploit a vulnerability in SUSE Manager to execute arbitrary program code with administrator privileges, leading to potential system compromise.

A malicious user with permission to edit the `local-path-config` ConfigMap in the `local-path-storage` namespace can manipulate the `helperPod.yaml` template used by `rancher/local-path-provisioner`. Security-sensitive fields such as `securityContext.privileged`, `hostPath` volumes, and Linux capabilities can be injected into the template, leading to a privileged pod running on the target node with the host root filesystem mounted.

Fleet's Helm deployer did not fully apply ServiceAccount impersonation in two code paths, allowing a tenant with git push access to a Fleet-monitored repository to read secrets from any namespace on every downstream cluster targeted by their `GitRepo`.

A path traversal vulnerability (CVE-2026-25705) exists in Rancher's Extensions through the `compressedEndpoint` field in a `UIPlugin` deployment, allowing malicious UI extensions to overwrite Rancher binaries, tamper with cluster state, or write to the host filesystem.

The 'Copy Fail' vulnerability (CVE-2026-31431) in the Linux kernel allows a local attacker to escalate privileges to root, potentially leading to container breakout and lateral movement in cloud environments.

A local privilege escalation vulnerability, dubbed 'Copy Fail' (CVE-2026-31431), affects Linux kernels released since 2017, allowing an unprivileged local attacker to gain root permissions by exploiting a logic bug in the authencesn cryptographic template.

SUSE Harvester's Rancher integration mechanism is vulnerable to a man-in-the-middle attack due to insecure TLS options, potentially leading to denial of service.
