Summary
In versions prior to 2026.9.1, Wizarr (an advanced user invitation and management system for media servers) evaluated wizard step Markdown in the application's non-sandboxed Jinja2 environment with application globals exposed. An authenticated user able to create steps, or an administrator importing an untrusted bundle through POST /settings/wizard/import, could execute arbitrary Python when rendering the stored step, potentially leading to OS command execution, disclosure of the Flask SECRET_KEY, access to connected service credentials and the database, and stored cross-site scripting. This issue is fixed in 2026.9.1.
Risk Assessment
An attacker can gain full control over the application, steal credentials, user data, and execute malicious scripts in administrators' browsers.
Recommendation
Update Wizarr to version 2026.9.1 or later to prevent dangerous code execution in the Jinja2 environment.

- CVE-2026-97693Critical
Yuxi from 0.6.0.beta1 until 0.7.1 has insufficient isolation between execution-capable Docker sandboxes and trusted application services. A low-privileged authenticated user can reach other tenants' sandbox APIs, access their files and secrets, execute commands in active sandboxes, and enumerate, create, or delete sandboxes through the unauthenticated provisioner without knowing administrator, database, or MinIO credentials.
- CVE-2026-57566Critical
Readest prior to 0.11.10 contains an unauthenticated /api/opds/proxy route that fetches an attacker-controlled URL server-side without restricting the scheme, blocking private, loopback, link-local, or metadata hosts, or revalidating destinations during redirects. The route also accepts caller-controlled outbound headers and Authorization values and reflects the upstream status and response body.
- CVE-2026-54378Critical
VitaFit cloud API before 2026-10-30 contained a broken access control vulnerability that allows any authenticated user to obtain temporary AWS credentials by calling the POST /front/user/s3/token/ endpoint. Attackers can use these improperly scoped credentials to list the shared storage bucket and read or overwrite other users' stored files.
- CVE-2026-102895Critical
GPUStack prior to 2.2.0 treated a loopback request source as the built-in administrator when force_auth_localhost was false, which was the default. A remote request could appear to originate from 127.0.0.1, allowing unauthenticated administrative access, including user and model changes, persistent administrator API-key creation, disclosure of worker and cloud-provider secrets, and code execution.
- CVE-2026-102894Critical
GPUStack from 0.7.1 until 2.2.2 contains an /auth/saml/callback endpoint that decodes SAML XML and uses its NameID and attributes to resolve or provision a user without verifying the signature, issuer, audience, destination, or time conditions. Any network client could submit an identity for an existing user, including an administrator, or provision a new account, even when SAML was not configured.
- CVE-2026-82418Critical
IBM Watson Speech Services Cartridge versions 4.0.0 through 5.4.0 contain a use-after-free vulnerability that could allow a remote attacker to execute arbitrary code.
- CVE-2026-122013Critical
A vulnerability was detected in Comfast CF-WR632AX 2.6.0.1 in an unknown functionality of /usr/bin/webmgnt within the Multipart Parser component. Manipulating the filename argument results in path traversal, the attack can be initiated remotely, the exploit is public, and the vendor did not respond.
- CVE-2025-71457Critical
vtenext 25.02 before 25.02.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to change any account password via hub/rpwd.php without token verification. Attackers knowing a valid user_name can send action=change_password to RecoverPwd::displayChangePwd() and log in as administrators lacking two-factor authentication.
- CVE-2026-121933Critical
A flaw has been found in Linksys E5350 1.0.00.037. This impacts the function save_settings of the file /wizard/apply.cgi of the Setup Wizard component. Manipulating the wizard_router_pwd argument can lead to missing authentication. The attack may be launched remotely, and the exploit has been published and may be used.
- CVE-2026-113373Critical
Sonatype Nexus Repository 3 Pro does not check the local account status when a user signs in through a configured SAML or OAuth2/OpenID Connect identity provider. A user whose account was disabled or locked by an administrator in Nexus Repository can sign in again with valid identity provider credentials for the same account and then receives a new session with the roles of that account.
Original NVD description (English source)
Wizarr is an advanced user invitation and management system for Jellyfin, Plex, Emby, and other media servers. Prior to 2026.9.1, wizard step Markdown supplied through the editor or imported bundles was evaluated by app/blueprints/wizard/routes.py in the application's non-sandboxed Jinja2 environment with application globals exposed. An authenticated user able to create steps, or an administrator importing an untrusted bundle through POST /settings/wizard/import, could execute arbitrary Python when GET /wizard/{server}/{idx} rendered the stored step; app/jinja_filters.py and app/services/wizard_widgets.py contained additional evaluation sinks. This could execute operating-system commands as the application user, disclose the Flask SECRET_KEY, access connected service credentials and the database, and produce stored cross-site scripting. This issue is fixed in 2026.9.1.
