### Summary The application allows users to upload files with scripts in the filename parameter. As a result, a malicious user can upload a script file to the system. When users in the application use the "Diff or Compare" functionality, they are affected by a Stored Cross-Site Scripting vulnerability. ### Details I found a Stored Cross-Site Scripting vulnerability in the "Diff or Compare" functionality. This issue occurs because the upload functionality allows users to upload files with special characters such as <, >, /, and " in the filename. This vulnerability can be mitigated by restricting file uploads to filenames containing only whitelisted characters, such as A-Z, 0-9, and specific special characters permitted by business requirements, like - or _ . ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ 1. On MobSF version 4.2.8, I clicked on "Unload & Analyze" button. ![0](https://github.com/user-attachments/assets/489013...

### Impact In Synapse versions before 1.120.1, enabling the `dynamic_thumbnails` option or processing a specially crafted request could trigger the decoding and thumbnail generation of uncommon image formats, potentially invoking external tools like Ghostscript for processing. This significantly expands the attack surface in a historically vulnerable area, presenting a risk that far outweighs the benefit, particularly since these formats are rarely used on the open web or within the Matrix ecosystem. For a list of image formats, as well as decoding libraries and helper programs used, see [the Pillow documentation](https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html). ### Patches Synapse 1.120.1 addresses the issue by restricting thumbnail generation to images in the following widely used formats: PNG, JPEG, GIF, and WebP. ### Workarounds - Ensure any image codecs and helper programs, such as Ghostscript, are patched against security vulnerabilities. - Uninst...

### Impact Synapse versions before 1.120.1 fail to properly validate invites received over federation. This vulnerability allows a malicious server to send a specially crafted invite that disrupts the invited user's `/sync` functionality. ### Patches Synapse 1.120.1 rejects such invalid invites received over federation and restores the ability to sync for affected users. ### Workarounds Server administrators can disable federation from untrusted servers. ### For more information If you have any questions or comments about this advisory, please email us at [security at element.io](mailto:[email protected]).
