## Goroutine Leak in Abacus SSE Implementation ### Summary A critical goroutine leak vulnerability has been identified in the Abacus server's Server-Sent Events (SSE) implementation. The issue occurs when clients disconnect from the `/stream` endpoint, as the server fails to properly clean up resources and terminate associated goroutines. This leads to resource exhaustion where the server continues running but eventually stops accepting new SSE connections while maintaining high memory usage. The vulnerability specifically involves improper channel cleanup in the event handling mechanism, causing goroutines to remain blocked indefinitely. ### [POC](https://github.com/JasonLovesDoggo/abacus/blob/main/docs/bugs/GHSA-vh64-54px-qgf8/test.py) ### Impact This vulnerability affects all versions of Abacus prior to v1.4.0. The issue causes: - Permanent unresponsiveness of the `/stream` endpoint after prolonged use - Memory growth that stabilizes at a high level but prevents proper functio...

### Impact User enumeration in database authentication in Flask-AppBuilder <= 4.5.3 and werkzeug >= 3.0.0. Allows for a non authenticated user to enumerate existing usernames by timing the response time from the server when brute forcing requests to login. ### Patches Upgrade to flask-appbuilder>=4.5.3 ### Workarounds Downgrade werkzeug to <3.0.0 ### References _Are there any links users can visit to find out more?_

### Summary Improper validation of select fields allows attackers to craft an input that crashes the system, resulting in a 500 status and making the entire site and administration panel unavailable. This clearly impacts the Availability aspect of the CIA triad (confidentiality, integrity, and availability), although the attack still has certain limitations. ### Details The attack involves injecting any invalid user role value (e.g. ">") into the Role=User parameter in the /panel/users/{name}/profile page, which is the user profile update page. Doing this will change the users data in a way that prevents users and then the entire site from loading. Even though the actual data change is minimal, the error is unrecoverable until a valid role parameter is restored by direct modification of the user account file. Proper validation of select fields will prevent extraneous valid from being accepted and making the entire site and administration panel unavailable. ### Patches - [**Formwork...

### Summary The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users. ### Impact The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability. ### Patches - [**Formwork 2.x** (aa3e9c6)](https://github.com/getformwork/formwork/commit/aa3e9c684035d9e8495169fde7c57d97faa3f9a2) escapes site title from panel header navigation. ### Details By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute. ### PoC  1.
