CVE-2026-941098.8 ALT—
——0openEQUELLA versions before 2026.1.0 contain a remote code execution vulnerability in FreeMarker template compilation due to an unsandboxed TemplateClassResolver configuration. Authenticated attackers can inject malicious template expressions through collection summaries, dashboard portlets, or MIME templates to instantiate dangerous classes like freemarker.template.utility.Execute and invoke Runtime.exec for arbitrary command execution.1dCVE-2026-925928.8 ALT42.1%
——13Craft CMS 4.8.0 through 4.18.5 and 5.0.0 through 5.10.12 sign an authenticated user's attacker-controlled license-shun cookie with the same key and format used to validate signed redirect parameters, because the HMAC signature is not bound to its purpose (Yii's cookieValidationKey is derived from the same Craft securityKey used for signed request parameters). An authenticated, non-administrator user (Control Panel access is not required) can set the cookie via the license-shun endpoint and transplant the signed envelope into the redirect parameter; on a successful login, Craft validates the signature and renders the authenticated bytes as an unsandboxed Twig template, where Twig's map filter accepts a string callback and allows PHP system() to execute arbitrary operating-system commands as the web-server user. Exploitation requires an account using password authentication without active 2FA, the default request configuration, and availability of PHP system(). The issue is fixed in 4.18.6 and 5.10.13.4dCVE-2026-880648.8 ALT48.9%
——15Backstage is an open framework for building developer portals. Prior to 1.14.6 and from 1.15.0 until 1.15.4, the @backstage/plugin-techdocs-node package insufficiently validates mkdocs.yml supplied by an authenticated user who can register or modify a TechDocs source. Unsafe Python YAML tags, markdown_extensions names and configuration, theme options, and extra_templates values can reach the documentation generator and cause unintended code execution. The resulting impact is limited to the files, credentials, network access, and other resources available to the TechDocs backend or build container. This issue is fixed in versions 1.14.6 and 1.15.4.5dCVE-2026-919258.8 ALT40.3%
——12Polyaxon through 2.16.4 renders operation specification fields with an unsandboxed Jinja2 environment during server-side run preparation, allowing authenticated users to execute arbitrary code. Attackers can submit runs with Jinja2 payloads in queue, namespace, conditions, presets, or dependencies fields to execute operating system commands in the scheduler process context, exposing database credentials and service tokens.6dCVE-2026-819106.5 MED16.0%
——5Concrete CMS 9 through 9.5.2 is vulnerable to Server-Side Template Injection (SSTI) in Theme Customizer via Unvalidated Style Values. Values submitted through the customizer (color channels and other style properties handled by ColorStyle and sibling Style classes such as FontFamilyStyle and ImageStyle) are interpolated into server-compiled LESS source without neutralization of LESS syntax, allowing a user with the Theme Customization permission to inject arbitrary LESS directives. By injecting the @import (inline) directive, an attacker can read arbitrary files on the server and reach internal network resources through PHP stream wrappers. The compiled output, including any disclosed file contents, is written to the site's publicly served CSS cache, exposing database credentials, private keys, and other application secrets, and enabling server-side request forgery. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.9 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N.
