Privilege Escalation and Local File Inclusion in mintplex-labs/anything-llm

Vulnerability Description

mintplex-labs/anything-llm is vulnerable to multiple security issues due to improper input validation in several endpoints. An attacker can exploit these vulnerabilities to escalate privileges from a default user role to an admin role, read and delete arbitrary files on the system, and perform Server-Side Request Forgery (SSRF) attacks. The vulnerabilities are present in the `/request-token`, `/workspace/:slug/thread/:threadSlug/update`, `/system/remove-logo`, `/system/logo`, and collector's `/process` endpoints. These issues are due to the application's failure to properly validate user input before passing it to `prisma` functions and other critical operations. Affected versions include the latest version prior to 1.0.0.
