Sandbox escape via prototype pollution in ThingsBoard (versions prior to v4.3.1.2) allows a TENANT_ADMIN-authenticated user to achieve arbitrary code execution within the tb-js-executor sandboxed JavaScript context. The flaw lets a rule-chain script reach the host realm through the `args.constructor.constructor` chain (e.g., synthesizing a Function that returns `process`), defeating the intended VM isolation. No public exploit identified at time of analysis, though the upstream regression test in PR #15600 effectively documents the escape technique.

Code injection in ThingsBoard 4.3.1.0 and 4.3.1.1 allows remote attackers to embed control characters and shell metacharacters into server-generated Docker Compose YAML files and MQTT publish commands via the /api/v1/provision endpoint's getGatewayDockerComposeFile and getMqttPublishCommand functions. Device credential fields - including clientId, userName, password, and credentialsId - are passed unsanitized into YAML and shell command construction, enabling injection of shell special characters such as $, backtick, and double-quote. No public exploit has been identified at time of analysis; SSVC rates exploitation as none and EPSS is 0.04%, though the RCE tag warrants scrutiny given the CVSS 4.0 score of only 2.3.

SVG-based server-side request forgery in ThingsBoard versions prior to 4.2.1 allows upload of crafted SVG files containing external URL references to the dashboard Image Upload Gallery, causing the platform to initiate unintended outbound HTTP requests toward internal network resources. All ThingsBoard deployments (community, professional edition) running versions before 4.2.1 are affected via this gallery feature. No public exploit code or CISA KEV listing exists at time of analysis; however, the upstream fix in PR #13927 - which adds a Content-Security-Policy response header rather than sanitizing SVG content at upload - indicates the primary exploitation path may be browser-mediated rather than purely server-side, warranting scrutiny of the PR:N (no privileges required) CVSS assignment.

A vulnerability classified as problematic was found in ThingsBoard up to 3.6.2. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.

ThingsBoard before 3.5 allows Server-Side Template Injection if users are allowed to modify an email template, because Apache FreeMarker supports freemarker.template.utility.Execute (for content sent. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.

An issue was discovered in ThingsBoard 3.4.1, allows low privileged attackers (CUSTOMER_USER) to gain escalated privileges (vertically) and become an Administrator (TENANT_ADMIN) or (SYS_ADMIN) on. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

ThingsBoard 3.4.1 could allow a remote attacker to gain elevated privileges because hard-coded service credentials (usable for privilege escalation) are stored in an insecure format.
