Title
Bolt CMS Server-Side Template Injection via Unsandboxed allow_twig Field Rendering
Summary
Bolt CMS renders content field values through Twig's full application-level Environment with no SandboxExtension registered anywhere in the codebase. In src/Entity/Field.php, getTwigValue calls shouldBeRenderedAsTwig, which gates rendering only on the field definition's allow_twig flag and a regex checking for , , or ; when true, the raw field value is compiled and rendered via with no sandboxing.

DjangoCRM - Server-Side Template Injection in Mass Mail Message Rendering
Summary
DjangoCRM's massmail module renders user-controlled EmlMessage fields (subject, content) through Django's Template constructor with no sanitization, in at least three locations: message_previews.py builds an f-string embedding message.subject/message.content directly into a Template call; email_creators.py passes eml_message.subject directly as a template string to Template; and helpers.py contains the same f-string interpolation pattern.

Title
ERPNext: Server-Side Template Injection leading to Remote Code Execution
Summary
ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.111.0 and 16.22.0, limited authenticated users can cross a permission boundary in Frappe safe execution because frappe.render_template is exposed without forcing restrict_globals, allowing server-side template injection and remote code execution. This issue is fixed in versions 15.111.0 and 16.22.0.

Title
Gitleaks Secret Exfiltration via Non-Hermetic Sprig Template Functions in Report Template Feature
Summary
Gitleaks prior to 8.30.1 contains a template injection vulnerability that allows attackers who can supply or influence report templates to read arbitrary environment variables and exfiltrate sensitive data by leveraging non-hermetic Sprig template functions. Attackers can craft malicious report templates using the env, expandenv, and getHostByName functions to extract credentials, tokens, and API keys from the host process and exfiltrate them through DNS queries, including secrets discovered during the scan itself.

Title
Orval: RCE via servers[].url -> unescaped request-URL template literal (with getBaseUrlFromSpecification)
Summary
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, an unescaped backtick in servers[0].url is emitted into request URL template literals generated when output.baseUrl.getBaseUrlFromSpecification is enabled without safe encoding. This permits attacker-controlled JavaScript to be evaluated when a generated request or URL-builder function is called, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/core/src/getters/route.ts function getFullRoute. This issue is fixed in version 8.21.0.

Title
Orval: RCE via OpenAPI path -> unescaped request-URL template literal (backtick breakout)
Summary
Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, an unescaped backtick in an OpenAPI path is emitted into request URL template literals generated for axios, fetch, react-query, and SWR clients without safe encoding. This permits attacker-controlled JavaScript to be evaluated when a generated request, URL-builder, or query-key function is called, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/core/src/getters/route.ts and route generation consumers. This issue is fixed in version 8.21.0.

Title
Phalcon Volt compiler `join` filter compile-time PHP code injection (SSTI lead to RCE)
Summary
Phalcon is a high-performance, full-stack PHP framework. In 5.15.0 and earlier, resolveFilter in phalcon/Mvc/View/Engine/Volt/Compiler.zep builds the join filter by inserting the raw separator and array token values into generated PHP without passing them through expression(). An attacker who can influence Volt template source can place quote-breaking content in a join argument, inject PHP into the compiled cache file, and execute it when Phalcon\Mvc\View\Engine\Volt::render() loads the template. This issue is fixed in version 5.16.0.

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.
