Details

Ashlar-Vellum Cobalt VS File Parsing Type Confusion Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of VS files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25245.

Summary
CPU exhaustion in SvelteKit remote form deserialization (experimental only)
Details

Versions of @sveltejs/kit prior to 2.52.2 with remote functions enabled are vulnerable to CPU exhaustion. Malformed form data can cause the server to become unresponsive while processing a request, resulting in denial of service.

Only applications using both experimental.remoteFunctions and form are vulnerable.
