@tinacms/cli inserts the raw Git branch value into the generated client.ts source without escaping or encoding. A Git-valid branch name can close the string literal and inject an arbitrary JavaScript expression that executes when the consumer build imports the generated client module.
A browser-based cross-origin request flaw in the Tina dev server allows an attacker-controlled website to cause arbitrary file creation inside the configured media upload directory on a developer machine running tinacms dev. No manual file upload is required. The attacker page builds the multipart request in JavaScript and sends it directly to the local Tina server. The browser blocks access to the response because of CORS, but the server still …
@tinacms/cli contains a Remote Code Execution vulnerability in its Forestry-to-Tina migration command. The internal helper addVariablesToCode unquotes any value matching the marker "TINA_INTERNAL:::(.?):::" inside the stringified collection JSON. User-supplied label and name fields from .forestry/**/.yml are placed into that JSON without any sanitisation. An attacker who controls a Forestry-style project can therefore inject arbitrary JavaScript into the generated tina/templates.{ts,js} file. The injected code is written at module top level, so …
The TinaCMS CLI development server exposes media endpoints that are vulnerable to path traversal, allowing attackers to read and write arbitrary files on the filesystem outside the intended media directory.
The TinaCMS CLI dev server configures Vite with server.fs.strict: false, which disables Vite's built-in filesystem access restriction. This allows any unauthenticated attacker who can reach the dev server to read arbitrary files on the host system
The TinaCMS CLI dev server combines a permissive CORS configuration (Access-Control-Allow-Origin: *) with the path traversal vulnerability (previously reported) to enable a browser-based drive-by attack. A remote attacker can enumerate the filesystem, write arbitrary files, and delete arbitrary files on developer's machines by simply tricking them into visiting a malicious website while tinacms dev is running.
tinacms uses the gray-matter package in an insecure way allowing attackers that can control the content of the processed markdown files, e.g., blog posts, to execute arbitrary code.
Tina search token leaked via lock file (tina-lock.json) in TinaCMS. Sites building with @tinacms/cli < 1.6.2 that use a search token are impacted. If your Tina-enabled website has search setup, you should rotate that key immediately.
Tinacms is a Git-backed headless content management system with support for visual editing. Sites being built with @tinacms/cli >= 1.0.0 && < 1.0.9 which store sensitive values in the process.env variable are impacted. These values will be added in plaintext to the index.js file. If you're on a version prior to 1.0.0 this vulnerability does not affect you. If you are affected and your Tina-enabled website has sensitive credentials stored …
