swagger-typescript-api vulnerable to code injection via unescaped `servers[0].url` in fetch http-client template

swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/code-gen-process.ts createApiConfig copies servers[0].url into apiConfig.baseUrl, and templates/base/http-clients/fetch-http-client.ejs interpolates apiConfig.baseUrl into the generated HttpClient baseUrl field without escaping, allowing an attacker-controlled OpenAPI spec to inject TypeScript static field code that executes when the generated fetch client module is imported. This issue is fixed in version 13.12.2.

Server-Side Template Injection in SecureTransport's Apache Velocity mail templates

A Server-Side Template Injection (SSTI) vulnerability was identified in the mail template functionality of the Axway SecureTransport product in version 5.5-20260326. This flaw allows an attacker with admin privileges to inject arbitrary Java code expressions, which are executed server-side when the template is rendered (i.e., during email sending). Successful exploitation of this flaw allows an attacker to execute arbitrary code on the server that results in full host compromise. This issue affects all Axway SecureTransport versions prior 5.5-20260528 update.

Craft CMS: Potential authenticated Remote Code Execution via referrer redirect

Craft CMS is a content management system (CMS). In versions 5.9.0 and above prior to 5.10.0, control panel users with the ability to edit entries can execute unsandboxed Twig code via the HTTP Referrer header, potentially leading to authenticated RCE. The issue happens when a user is saving entries. Strings for a signed redirect URL are being compiled as a Twig template via renderObjectTemplate(), and while a sandboxed alternative already exists (renderSandboxedObjectTemplate()), it is not used in this case. This signed URL can be specified by users, as it is reflected in the “Referer” HTTP request header, which is under attacker control. This issue has been fixed in version 5.10.0.

Jupyter Enterprise Gateway: Jinja2 Template Server Side Template Injection results in Remote Code Execution

Jupyter Enterprise Gateway launches remote Jupyter Notebook kernels across distributed clusters like Apache Spark, Kubernetes, and Docker Swarm. In versions 2.0.0rc2 and above, prior to 3.3.0, the environment variables (KERNEL_XXX) used during the rendering of the Kubernetes manifest are vulnerable to Server Side Template Injection (SSTI). By including Jinja2 template expressions it is possible to execution Python code and OS Commands in the Enterprise Gateway service. The code can use or steal the Kubernetes service account token, which can steal Kubernetes secrets and be used to fully compromise the Kubernetes cluster by scheduling a privileged pod or a pod with a hostPath volume mount. This issue has been fixed in version 3.3.0.

Gitleaks Secret Exfiltration via Non-Hermetic Sprig Template Functions in Report Template Feature

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.

Pimcore CMS 12.3.8 Twig Sandbox Bypass via SecurityPolicy checkMethodAllowed

Pimcore CMS/DXP version 12.3.8 contains a sandbox bypass vulnerability that allows authenticated administrative attackers to execute arbitrary methods on PHP objects by exploiting empty checkMethodAllowed() and checkPropertyAllowed() implementations in the custom Twig SecurityPolicy. Attackers can supply malicious Twig templates through the DataObject ClassDefinition Layout\Text component to perform arbitrary file reads, execute arbitrary database queries, and potentially achieve remote code execution via PHP object gadget chains, with the pimcore_* function wildcard further broadening the bypass to all Pimcore Twig functions.

Gogs: DoS in rendering issue index pattern

Gogs is an open source self-hosted Git service. Prior to 0.14.3, specially crafted issue index pattern can cause a panic when rendering, resulting in denial of service. In internal/markup/markup.go, RenderIssueIndexPattern renders the issue index pattern to a link using com.Expand, which is not safe: when the configured pattern contains an opening brace { but no closing brace }, strings.Index(template, "}") returns -1 and the subsequent slice template[:-1] triggers a panic. Once such a pattern is set, any page in the affected repository that contains an issue index reference such as #1 becomes unavailable. This vulnerability is fixed in 0.14.3.

FOSSBilling: Server-side template injection in Twig template rendering enables information disclosure and RCE

FOSSBilling is a free, open-source billing and client management system. Versions prior to 0.8.0 have a Server-Side Template Injection (SSTI) vulnerability in the template rendering system. Administrators with access to features that render Twig templates (email templates, mass mail campaigns, custom payment adapters, and the `string_render` API endpoint) can inject arbitrary Twig expressions, leading to information disclosure and remote code execution. The vulnerability exists because Twig templates are rendered without a sandbox, allowing access to the full Twig environment, API context, and the application's dependency injection container. Version 0.8.0 patches the issue. Some workarounds are available. Audit existing email templates for suspicious Twig expressions, rotate all admin and client API tokens, and/or block external access to /api/system/* at reverse proxy/WAF to mitigate chaining with GHSA-78x5-c8gw-8279.
