### Summary ```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. ### Details The ```gray-matter``` package executes by default the code in the markdown file's front matter. ```tinacms``` does not change this behavior when process markdown file, e.g., by passing a custom engine property for js/javascript in the options object. ### PoC 1. Create a tinacms app using the cli/documentation: ``` npx create-tina-app@latest ``` 2. Modify one of the blog posts to contain the following front matter: ```js ---js { "title": "Pawned" + console.log(require("fs").readFileSync("/etc/passwd").toString()) } --- ``` 3. Start the tinacms server, e.g., with ```npm run dev``` 4. Observe the console of the server printing the password file, showing that attackers can execute arbitrary commands. ### Impact RCE: attackers can execute arbitrary JavaScript code on th...

## Summary S3 Encryption Client for Java is an open-source client-side encryption library used to facilitate writing and reading encrypted records to S3. When the encrypted data key (EDK) is stored in an "Instruction File" instead of S3's metadata record, the EDK is exposed to an "Invisible Salamanders" attack (https://eprint.iacr.org/2019/016), which could allow the EDK to be replaced with a new key. ## Impact ### Background - Key Commitment There is a cryptographic property whereby under certain conditions, a single ciphertext could be decrypted into 2 different plaintexts by using different encryption keys. To address this issue, strong encryption schemes use what is known as "key commitment", a process by which an encrypted message can only be decrypted by one key; the key used to originally encrypt the message. In older versions of S3EC, when customers are also using a feature called "Instruction File" to store EDKs, key commitment is not implemented because multiple E...
