# Vulnerability Report: SMTP Header Injection via Regex Bypass **Vulnerable Code:** `mailpit/internal/smtpd/smtpd.go` ## Executive Summary Mailpit's SMTP server is vulnerable to **Header Injection** due to an insufficient Regular Expression used to validate `RCPT TO` and `MAIL FROM` addresses. An attacker can inject arbitrary SMTP headers (or corrupt existing ones) by including carriage return characters (`\r`) in the email address. This header injection occurs because the regex intended to filter control characters fails to exclude `\r` and `\n` when used inside a character class. ## RFC Compliance & Design Analysis **"Is this behavior intentional for a testing tool?"** No. While testing tools are often permissive, this specific behavior violates the core SMTP protocol and fails the developer's own intent. 1. **RFC 5321 Violation:** The SMTP protocol strictly forbids Control Characters (CR, LF, Null) in the envelope address (`Mailbox`). * *RFC 5321 Section 4.1.2:* A `Mailbo...

### Summary A stored Cross-Site Scripting (XSS) vulnerability in the Mermaid artifact renderer allows attackers to execute arbitrary JavaScript within the application context. This XSS can be escalated to Remote Code Execution (RCE) by leveraging the exposed `electronAPI` IPC bridge, allowing attackers to run arbitrary system commands on the victim's machine. ### Details The vulnerability exists in the `Renderer` component responsible for rendering Mermaid diagrams within chat artifacts. ```TypeScript case 'application/lobe.artifacts.mermaid': { return <Mermaid variant={'borderless'}>{content}</Mermaid>; } ``` The `content` variable, which is derived from user or AI-generated messages, is passed directly to the `<Mermaid>` component without any sanitization. The Mermaid library renders HTML labels (e.g., nodes defined with ["..."]) directly into the DOM. If the content contains malicious HTML tags (like <img onerror=...>), they are executed. In the Desktop version, the application...

### Summary The [commit](https://github.com/esm-dev/esm.sh/commit/9d77b88c320733ff6689d938d85d246a3af9af16) does not actually fix the path traversal bug. `path.Clean` basically normalizes a path but does not prevent absolute paths in a malicious tar file. ### PoC This test file can demonstrate the basic idea pretty easily: ```go package server import ( "archive/tar" "bytes" "compress/gzip" "testing" ) // TestExtractPackageTarball_PathTraversal tests the extractPackageTarball function // with a malicious tarball containing a path traversal attempt func TestExtractPackageTarball_PathTraversal(t *testing.T) { // Create a temporary directory for testing installDir := "./testdata/good" // Create a malicious tarball with path traversal var buf bytes.Buffer gw := gzip.NewWriter(&buf) tw := tar.NewWriter(gw) // Add a normal file content := []byte("export const foo = 'bar';") header := &tar.Header{ Name: "package/index.js", Mode: 0644, Size: int64(len(cont...

# Kimai 2.45.0 - Authenticated Server-Side Template Injection (SSTI) ## Vulnerability Summary | Field | Value | |-------|-------| | **Title** | Authenticated SSTI via Permissive Export Template Sandbox || **Attack Vector** | Network | | **Attack Complexity** | Low | | **Privileges Required** | High (Admin with export permissions and server access) | | **User Interaction** | None | | **Impact** | Confidentiality: HIGH (Credential/Secret Extraction) | | **Affected Versions** | Kimai 2.45.0 (likely earlier versions) | | **Tested On** | Docker: kimai/kimai2:apache-2.45.0 | | **Discovery Date** | 2026-01-05 | --- **Why Scope is "Changed":** The extracted `APP_SECRET` can be used to forge Symfony login links for ANY user account, expanding the attack beyond the initially compromised admin context. --- ## Vulnerability Description Kimai's export functionality uses a Twig sandbox with an overly permissive security policy (`DefaultPolicy`) that allows arbitrary method calls on objects av...

### Summary The `getSecretKey` template function, while introduced for senhasegura Devops Secrets Management (DSM) provider, has the ability to fetch secrets cross-namespaces with the roleBinding of the external-secrets controller, bypassing our security mechanisms. This function was completely removed, as everything done with that templating function can be done in a different way while respecting our safeguards (for example, using `sourceRef` like explained here: https://github.com/external-secrets/external-secrets/issues/5690#issuecomment-3630977865) ### Impact - Cross-namespace secret access: Attackers or misconfigured resources could retrieve secrets from namespaces other than the one intended. - privilege escalation: Unauthorized access to secrets could lead to privilege escalation, data exfiltration, or compromise of service accounts and credentials. ### Resolution We removed the incriminated templating function from our codebase. All users should upgrade to the latest vers...

### Summary A security vulnerability exists in `@fastify/express` where middleware registered with a specific path prefix can be bypassed using URL-encoded characters (e.g., `/%61dmin` instead of `/admin`). While the middleware engine fails to match the encoded path and skips execution, the underlying Fastify router correctly decodes the path and matches the route handler, allowing attackers to access protected endpoints without the middleware constraints. ### Details The vulnerability is caused by how `@fastify/express` matches requests against registered middleware paths. ### PoC **Step 1:** Run the following Fastify application (save as `app.js`): ```javascript const fastify = require('fastify')({ logger: true }); async function start() { // Register fastify-express for Express-style middleware support await fastify.register(require('@fastify/express')); // Middleware to block /admin route fastify.use('/admin', (req, res, next) => { res.statusCode = 403; res.end...

### Summary A security vulnerability exists in `@fastify/middie` where middleware registered with a specific path prefix can be bypassed using URL-encoded characters (e.g., `/%61dmin` instead of `/admin`). While the middleware engine fails to match the encoded path and skips execution, the underlying Fastify router correctly decodes the path and matches the route handler, allowing attackers to access protected endpoints without the middleware constraints. ### Details The vulnerability is caused by how `middie` matches requests against registered middleware paths. 1. **Regex Generation**: When [fastify.use('/admin', ...)](cci:1://file:///Users/harshjaiswal/work/research/nest/packages/platform-fastify/adapters/fastify-adapter.ts:733:2-741:3) is called, `middie` uses `path-to-regexp` to generate a regular expression for the path `/admin`. 2. **Request Matching**: For every request, `middie` executes this regular expression against `req.url` (or `req.originalUrl`). 3. **The Flaw**: `r...

### Summary Wings does not consider SQLite max parameter limit when processing activity log entries allowing for low privileged user to trigger a condition that floods the panel with activity records ### Details After wings sends activity logs to the panel it deletes the processed activity entries from the wings SQLite database. However, it does not consider the max parameter limit of SQLite, 32766 as of SQLite 3.32.0. If wings attempts to delete more than 32766 entries from the SQLite database in one query, it triggers an error (SQL logic error: too many SQL variables (1)) and does not remove any entries from the database. These entries are then indefinitely re-processed and resent to the panel each time the cron runs. https://github.com/pterodactyl/wings/blob/9ffbcdcdb1163da823cf9959b9602df9f7dcb54a/internal/cron/activity_cron.go#L81 https://github.com/pterodactyl/wings/blob/9ffbcdcdb1163da823cf9959b9602df9f7dcb54a/internal/cron/sftp_cron.go#L86 ### PoC Any method that can ...
