Details

BullWall Ransomware Containment contains excluded file paths, such as '$recycle.bin' that are not monitored. An attacker with file write permissions could bypass detection by renaming a directory. Versions 4.6.0.0, 4.6.0.6, 4.6.0.7, and 4.6.1.4 were confirmed to be affected; other versions before and after may also be affected.

xdg-open in xdg-utils through 1.2.1 can send requests containing SameSite=Strict cookies, which can facilitate CSRF. NOTE: this is disputed because integrations of xdg-open typically do not provide information about whether the xdg-open command and arguments were manually entered by a user, or whether they were the result of a navigation from content in an untrusted origin.

Details

An internal product security audit of Lenovo XClarity Orchestrator (LXCO) discovered the below vulnerability:

An attacker with access to a device on the local Lenovo XClarity Orchestrator (LXCO) network segment may be able to manipulate the local device to create an alternate communication channel which could allow the attacker, under certain conditions, to directly interact with backend LXCO API services typically inaccessible to users. While access controls may limit the scope of interaction, this could result in unauthorized access to internal functionality or data. This issue is not exploitable from remote networks.

Vulnerability from github – Published: 2025-04-08 18:34 – Updated: 2025-04-08 18:34

Details

IBM Personal Communications v14 and v15 include a Windows service that is vulnerable to local privilege escalation (LPE). The vulnerability allows any interactively logged in users on the target computer to run commands with full privileges in the context of NT AUTHORITY\SYSTEM. This allows for a low privileged attacker to escalate their privileges. This vulnerability is due to an incomplete fix for CVE-2024-25029.

Vulnerability from github – Published: 2022-02-15 01:57 – Updated: 2023-01-06 22:23

Summary
Improper Authentication in Kubernetes
Details

A security issue was discovered in the Kubelet and kube-proxy components of Kubernetes which allows adjacent hosts to reach TCP and UDP services bound to 127.0.0.1 running on the node or in the node's network namespace. For example, if a cluster administrator runs a TCP service on a node that listens on 127.0.0.1:1234, because of this bug, that service would be potentially reachable by other hosts on the same LAN as the node, or by containers running on the same node as the service. If the example service on port 1234 required no additional authentication (because it assumed that only other localhost processes could reach it), then it could be vulnerable to attacks that make use of this bug.

Vulnerability from github – Published: 2026-05-11 16:17 – Updated: 2026-05-11 16:17
VLAI
Summary
LiteLLM has a sandbox escape in custom-code guardrail
Details

Impact

The POST /guardrails/test_custom_code endpoint runs user-supplied Python inside a hand-rolled sandbox. The sandbox can be escaped using bytecode-level techniques, allowing arbitrary code execution in the proxy process — which runs as root in the default Docker image.

Reaching the endpoint requires a proxy-admin credential in default configurations.

Patches

Fixed in 1.83.11. The hand-rolled sandbox has been replaced with RestrictedPython. Upgrade to 1.83.11 or later.

Workarounds

If upgrading is not immediately possible, block POST /guardrails/test_custom_code at your reverse proxy or API gateway.
