Details

In Versa Analytics, the cron jobs are used for scheduling tasks by executing commands at specific dates and times on the server. If the job is run as the user root, there is a potential privilege escalation vulnerability. In this case, the job runs a script as root that is writable by users who are members of the versa group.

Summary
hermes-agent has a sandbox issue
Details

A vulnerability was identified in NousResearch hermes-agent up to 2026.4.16. This impacts the function execute_code of the file tools/code_execution_tool.py of the component Environment Variable Handler. Such manipulation leads to sandbox issue. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

GHSA-WMGG-3P4H-48X7

Vulnerability from github – Published: 2026-06-30 18:18 – Updated: 2026-06-30 18:18
VLAI
Summary
Fission Environment CRD PodSpec Injection Leading to Node Escape and Cluster Takeover
Details

Summary

A stronger framing of the same root cause as GHSA-gx55-f84r-v3r7: the Environment.spec.runtime.podSpec / spec.builder.podSpec passthrough lacked validation, and MergePodSpec propagated dangerous fields into the generated pods.

Details

Three independent flaws compounded:

  1. Validate gap. pkg/apis/core/v1/validation.go::Environment.Validate checked only container naming conventions, never hostPID/hostIPC/hostNetwork/hostPath/privileged.
  2. UPDATE bypass. The pkg/webhook/environment.go kubebuilder marker registered verbs=create only. A tenant could kubectl apply a clean Environment and then kubectl patch in the dangerous fields — the webhook was never called.
  3. Merge propagation. pkg/executor/util/merge.go::MergePodSpec unconditionally forwarded HostPID, HostIPC, HostNetwork, Volumes (including hostPath), SecurityContext, and ServiceAccountName into the Deployments generated by poolmgr / newdeploy / buildermgr.

A kubectl apply plus a follow-up kubectl patch caused poolmgr to schedule a privileged pod with a host-root mount within roughly 20 seconds. From that pod the cluster CA private key was readable, allowing the attacker to sign arbitrary kubelet certificates and achieve full cluster takeover.

Impact

environments.fission.io create/update RBAC is escalated to node escape and, via the readable cluster CA key, full cluster takeover.

Fix

Fixed in #3391 (with the companion buildermgr SA-token fix in #3390) and released in v1.24.0. Each enumerated flaw is addressed:

  1. Validate — ValidatePodSpecSafety is called from Environment.Validate for both Runtime.PodSpec and Builder.PodSpec.
  2. UPDATE bypass — the webhook marker is extended to verbs=create;update; chart and envtest manifests are aligned.
  3. Merge propagation — host namespaces, ServiceAccountName, and hostPath volumes are stripped at the merge layer; per-container privileged/allowPrivilegeEscalation and dangerous capabilities are sanitized.

See GHSA-gx55-f84r-v3r7 for the detailed fix — both advisories close to the same commit.

Duplicate handling

This advisory and GHSA-gx55-f84r-v3r7 were reported separately but close to the same code fix. Both are published to acknowledge each reporter's contribution and to keep the public CVE record clear about the multi-layer nature of the issue.

Concrete CMS has a session-hardening bypass and allows password change without reauthorization
Details

Concrete CMS 9.5.0 and below is vulnerable to password change without reauthorization and session-hardening bypass. The user-profile edit controller passes the entire raw POST array to UserInfo::update() without field whitelisting resulting in password change without requiring the current password  and also resulting in registered users able to disable the per-user-IP-pinning in the session validator which is meant to detect hijacking.

Severity
5.3 (Medium)

Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-48
Architecture and Design

Strategy: Separation of Privilege

Follow the principle of least privilege when assigning access rights to entities in a software system.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.

CAPEC-122: Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.

CAPEC-233: Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

CAPEC-58: Restful Privilege Elevation

An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
