Title
Server-Side Template Injection in extension "Event management and registration" (sf_event_mgt)
Summary
The extension passes an editor-configurable email subject string directly into a Fluid template source without restriction. A backend user with edit access to the event plugin or Backend Module can supply Fluid ViewHelper syntax in this field to disclose sensitive data or execute TypoScript content objects. Exploitation of this issue requires an authenticated backend account with edit access to the event registration plugin or backend module.

grav-plugin-api before 1.0.15 Twig SSTI via translate endpoint
Summary
grav-plugin-api versions before 1.0.15 fail to validate Twig content in the translate() endpoint, allowing attackers with api.pages.write permission to persist pages with process.twig enabled. Attackers can submit crafted header and content parameters to execute server-side template injection payloads that are evaluated at render time.

Title
Grav before 4.2.2 Remote Code Execution via Email Twig
Summary
The Grav Email plugin (getgrav/grav-plugin-email) before 4.2.2 renders page-editor-controlled Email action parameters as unsandboxed Twig templates. An authenticated remote user with only api.access and api.pages.write permissions can place a Twig expression in header.form.process.email.body, publish the page, and submit the form to execute an arbitrary operating-system command as the account running PHP.

Title
Fleet: DNS exfiltration via Sprig getHostByName in fleet.yaml Helm template preprocessing
Summary
A security vulnerability was discovered in Fleet's Helm template preprocessing where templates evaluated by the Fleet controller could reach network resources outside the management cluster. A user who can supply bundle content to a repository referenced by a `GitRepo` resource can cause the Fleet controller to:
- Disclose cluster metadata available to the templating context.
- Reveal information about hosts reachable from the controller's network position.
Because the disclosure channel is name resolution, it may remain effective in environments where outbound traffic is otherwise restricted. The disclosed information is limited to values exposed to the Fleet templating context and to name resolution results. Integrity and availability of managed clusters are not affected.
This issue affects Fleet:
from 0.12.0 before 0.12.19,
from 0.13.0 before 0.13.15,
from 0.14.0 before 0.14.10,
from 0.15.0 before 0.15.6, and
from 0.16.0 before 0.16.1.

Oh My Posh: Arbitrary command execution via template injection in the path segment
Summary
Oh My Posh is the most customisable and low-latency cross platform/shell prompt renderer. Prior to 29.35.1, the setStyle() function in src/segments/path.go passed pt.Path, which includes raw folder names, to template.Render, whose function map exposes cmd, so an attacker-controlled directory name containing a Go template expression could execute arbitrary operating system commands as the current user whenever the prompt rendered inside that directory or a descendant. This issue is fixed in version 29.35.1.

Title
CamaleonCMS 2.9.1 Server-Side Template Injection via test_email Action
Summary
CamaleonCMS 2.9.1 contains a server-side template injection vulnerability that allows authenticated administrators to execute arbitrary commands by embedding ERB tags in the email parameter of the test_email settings action, which are evaluated when an SMTP rejection reflects the recipient address back in the exception message rendered as an inline ERB template. Attackers can submit a crafted email parameter containing ERB expressions through the admin settings test_email endpoint, causing the Rails inline template renderer to evaluate attacker-controlled Ruby code and achieve arbitrary command execution as the Rails process user.

Title
Prompty: Server-Side Template Injection to Remote Code Execution in the @prompty/core Nunjucks Renderer
Summary
Prompty is a markdown file format (.prompty) for LLM prompts. Prior to 0.1.5 and 2.0.0-beta.5, the TypeScript Nunjucks renderer evaluated untrusted .prompty template bodies with unrestricted JavaScript member access. An attacker-controlled template could traverse constructor and prototype properties to execute JavaScript in the host Node.js process. This issue is fixed in versions 0.1.5 and 2.0.0-beta.5.

Title
ERPNext: Possibility of server-side template injection due to missing validation
Summary
ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.118.0 and 16.29.0, the validate_template and render_template calls in erpnext/accounts/doctype/process_statement_of_accounts/process_statement_of_accounts.py render subject, body, and pdf_name fields with unrestricted globals including frappe.utils, allowing an authenticated user with a common operational role to inject template expressions, execute arbitrary server-side code, and read data across the application. This issue is fixed in versions 15.118.0 and 16.29.0.
