### Impact It was possible to overwrite Git configuration remotely and override some of its behavior. ### Resources Thanks to Jason Marcello for responsible disclosure.

### Impact It was possible to read arbitrary files from the server file system using crafted symbolic links in the repository. ### Resources Thanks to Jason Marcello for responsible disclosure.

### Summary On Windows, converting a notebook containing SVG output to a PDF results in unauthorized code execution. Specifically, a third party can create a `inkscape.bat` file that defines a [Windows batch script](https://en.wikipedia.org/wiki/Batch_file), capable of arbitrary code execution. When a user runs `jupyter nbconvert --to pdf` on a notebook containing SVG output to a PDF on a Windows platform from this directory, the `inkscape.bat` file is run unexpectedly. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ `nbconvert` searches for an `inkscape` executable when converting notebooks to PDFs here: https://github.com/jupyter/nbconvert/blob/4f61702f5c7524d8a3c4ac0d5fc33a6ac2fa36a7/nbconvert/preprocessors/svg2pdf.py#L104 The MITRE page on [CWE-427 (Uncontrolled Search Path Element)](https://cwe.mitre.org/data/definitions/427.html) summarizes the root cause succinctly: > In Windows-based systems...

## Summary S3 Encryption Client for PHP 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 can 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 EDK...

On December 11th, the Storybook team received a responsible disclosure alerting them to a potential vulnerability in certain built and published Storybooks. The vulnerability is a bug in how Storybook handles environment variables defined in a `.env` file, which could, in specific circumstances, lead to those variables being unexpectedly bundled into the artifacts created by the `storybook build` command. When a built Storybook is published to the web, the bundle’s source is viewable, thus potentially exposing those variables to anyone with access. If those variables contained secrets, they should be considered compromised. ## Who is impacted? For a project to be vulnerable to this issue, it must: - Build the Storybook (i.e. run `storybook build` directly or indirectly) in a directory that contains a `.env` file (including variants like `.env.local`) - The `.env` file contains sensitive secrets - Use Storybook version `7.0.0` or above - Publish the built Storybook to the web Stor...

### 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...

A critical authentication bypass vulnerability exists in Ollama platform's API endpoints in versions prior to and including v0.12.3. The platform exposes multiple API endpoints without requiring authentication, enabling remote attackers to perform unauthorized model management operations.
