Title
BottleCRM through 1.14.5 Server-Side Template Injection via Account Email create_mail
Summary
BottleCRM through 1.14.5 contains a server-side template injection vulnerability in the send_email Celery task, which compiles the user-supplied AccountEmail message_body with django.template.Template(). Authenticated organization members can submit template tags through POST /api/accounts/<id>/create_mail/ to disclose the rendering context and loaded Python modules, or block the shared Celery worker with nested loops.

Title
Frappe ERPNext before 15.119.1 Server-Side Template Injection via Message Fields
Summary
Frappe ERPNext before 15.119.1 and 16.x before 16.32.0 contains a server-side template injection vulnerability because user-controlled message fields are not validated before template rendering, allowing expressions to run in an unrestricted context. Authenticated attackers holding a common operational role can inject template expressions to read and write arbitrary database data, delete documents, send outbound requests from the server, and send mail from the site.

Title
Wizarr: Authenticated Server-Side Template Injection (SSTI) in wizard step rendering leads to Remote Code Execution (RCE)
Summary
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.

Title
Backstage: Improper validation of MkDocs theme configuration in TechDocs
Summary
Backstage is an open framework for building developer portals. Prior to 1.14.6, the @backstage/plugin-techdocs-node package is affected by improper validation of mkdocs theme configuration in techdocs. When TechDocs is configured to build documentation locally or in a container, a user with write access to a registered repository can include configuration values in mkdocs.yml that cause arbitrary code execution during the documentation build process. This issue is fixed in versions 1.14.6 and 1.15.4.

Title
Authenticated RCE via render-components Entry Type overrides
Summary
Craft CMS 5.10.13.2 contains an authenticated remote code execution vulnerability in the Control Panel action app/render-components.
Any authenticated user with basic Control Panel access can submit request-controlled component classes and property overrides. By first overriding an EntryType object’s uiLabelFormat and then rendering an Entry that resolves the same request-cached entry type, an attacker can cause arbitrary Twig supplied in the request to be evaluated by renderObjectTemplate().
This render path is not sandboxed. A Twig string callable can therefore reach PHP functions such as system(), resulting in operating-system command execution with the privileges of the PHP/web-server process.
The issue was reproduced with an active non-admin Craft Team user with no optional permissions enabled. No access to entry-editing, Settings, utility, user-management, project-config, filesystem, Kubernetes, or environment variables was required.

Title
fsspec: Server-Side Template Injection in ReferenceFileSystem leads to Remote Code Execution
Summary
fsspec is a specification and Python implementation framework for filesystem interfaces. From 0.9.0 until 2026.6.0, fsspec.implementations.reference.ReferenceFileSystem evaluates fields from Kerchunk reference JSON documents through unrestricted jinja2.Template(...).render(...) calls in _process_references1._render_jinja, _process_templates, and _process_gen in fsspec/implementations/reference.py. A document supplied inline or fetched from an attacker-controlled URL can provide template expressions that execute Python code when the reference filesystem is opened, including through consumers such as xarray, before referenced data is read. The _process_gen path is reached whenever a document includes a gen array, while the other paths depend on template-related options and values. This issue is fixed in version 2026.6.0.

"value": "fsspec is a specification and Python implementation framework for filesystem interfaces. From 0.9.0 until 2026.6.0, fsspec.implementations.reference.ReferenceFileSystem evaluates fields from Kerchunk reference JSON documents through unrestricted jinja2.Template(...).render(...) calls in _process_references1._render_jinja, _process_templates, and _process_gen in fsspec/implementations/reference.py. A document supplied inline or fetched from an attacker-controlled URL can provide template expressions that execute Python code when the reference filesystem is opened, including through consumers such as xarray, before referenced data is read. The _process_gen path is reached whenever a document includes a gen array, while the other paths depend on template-related options and values. This issue is fixed in version 2026.6.0."

Mitigation
Architecture and Design
Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
Mitigation
Implementation
Use the template engine's sandbox or restricted mode, if available.
