Title
Frappe may be vulnerable remote code execution due to server-side template injection
Summary
Frappe is a full-stack web application framework. Prior to versions 14.99.6 and 15.88.1, an authenticated user with specific permissions could be tricked into accessing a specially crafted link. This could lead to a malicious template being executed on the server, resulting in remote code execution. Versions 14.99.6 and 15.88.1 fix the issue. No known workarounds are available.

Title
Craft CMS vulnerable to potential authenticated Remote Code Execution via Twig SSTI
Summary
Craft is a platform for creating digital experiences. Versions 5.0.0-RC1 through 5.8.20 and 4.0.0-RC1 through 4.16.16 are vulnerable to potential authenticated Remote Code Execution via Twig SSTI. For this to work, users must have administrator access to the Craft Control Panel, and allowAdminChanges must be enabled, which is against Craft CMS' recommendations for any non-dev environment. Alternatively, a non-administrator account with allowAdminChanges disabled can be used, provided access to the System Messages utility is available. It is possible to craft a malicious payload using the Twig `map` filter in text fields that accept Twig input under Settings in the Craft control panel or using the System Messages utility, which could lead to a RCE. Users should update to the patched versions (5.8.21 and 4.16.17) to mitigate the issue.

CVE-2025-66299 (GCVE-0-2025-66299)

Vulnerability from cvelistv5 – Published: 2025-12-01 21:15 – Updated: 2025-12-02 14:07

Title
Security Sandbox Bypass with SSTI (Server Side Template Injection) in the Grav CMS
Summary
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, Grav CMS is vulnerable to a Server-Side Template Injection (SSTI) that allows any authenticated user with editor permissions to execute arbitrary code on the remote server, bypassing the existing security sandbox. Since the security sandbox does not fully protect the Twig object, it is possible to interact with it (e.g., call methods, read/write attributes) through maliciously crafted Twig template directives injected into a web page. This allows an authenticated editor to add arbitrary functions to the Twig attribute system.twig.safe_filters, effectively bypassing the Grav CMS sandbox. This vulnerability is fixed in 1.8.0-beta.27.
Severity
8.8 (High)

Title
Grav is vulnerable to Server-Side Template Injection (SSTI) via Forms
Summary
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, having a simple form on site can reveal the whole Grav configuration details (including plugin configuration details) by using the correct POST payload to exploit a Server-Side Template (SST) vulnerability. Sensitive information may be contained in the configuration details. This vulnerability is fixed in 1.8.0-beta.27.
Severity

Title
Grav vulnerable to Privilege Escalation and Authenticated Remote Code Execution via Twig Injection
Summary
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, a user with admin panel access and permissions to create or edit pages in Grav CMS can enable Twig processing in the page frontmatter. By injecting malicious Twig expressions, the user can escalate their privileges to admin or execute arbitrary system commands via the scheduler API. This results in both Privilege Escalation (PE) and Remote Code Execution (RCE) vulnerabilities. This vulnerability is fixed in 1.8.0-beta.27.
Severity
7.4 (High)

Title
Grav is vulnerable to RCE via SSTI through Twig Sandbox Bypass
Summary
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, a Server-Side Template Injection (SSTI) vulnerability exists in Grav that allows authenticated attackers with editor permissions to execute arbitrary commands on the server and, under certain conditions, may also be exploited by unauthenticated attackers. This vulnerability stems from weak regex validation in the cleanDangerousTwig method. This vulnerability is fixed in 1.8.0-beta.27.

Title
LangChain Vulnerable to Template Injection via Attribute Access in Prompt Templates
Summary
LangChain is a framework for building agents and LLM-powered applications. From versions 0.3.79 and prior and 1.0.0 to 1.0.6, a template injection vulnerability exists in LangChain's prompt template system that allows attackers to access Python object internals through template syntax. This vulnerability affects applications that accept untrusted template strings (not just template variables) in ChatPromptTemplate and related prompt template classes. This issue has been patched in versions 0.3.80 and 1.0.7.

CVE-2025-62416 (GCVE-0-2025-62416)

Vulnerability from cvelistv5 – Published: 2025-10-16 18:32 – Updated: 2025-10-17 14:32
VLAI
Title
bagisto - Server Side Template Injection (SSTI) in Product Description
Summary
Bagisto is an open source laravel eCommerce platform. Bagisto v2.3.7 is vulnerable to Server-Side Template Injection (SSTI) due to unsanitized user input being processed by the server-side templating engine when rendering product descriptions. This allows an attacker with product creation privileges to inject arbitrary template expressions that are evaluated by the backend — potentially leading to Remote Code Execution (RCE) on the server. This vulnerability is fixed in 2.3.8.
Severity
5.1 (Medium)

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.
