Detailsinfo

A vulnerability was found in karakeep-app karakeep up to 0.31.x. It has been declared as critical. Affected by this vulnerability is an unknown function of the component HTTP Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Karakeep is a elf-hostable bookmark-everything app. A Server-Side Request Forgery (SSRF) protection bypass vulnerability was identified in versions prior to 0.32.0 affecting redirect-following processing components. Although the application implements protections intended to prevent requests toward internal/private network destinations, these protections could be bypassed through crafted HTTP redirect chains. By leveraging attacker-controlled redirects, an authenticated user could cause vulnerable application components to initiate requests toward internally reachable Docker network services accessible from the application environment. The issue affected multiple processing paths, including crawler-related functionality and video download processing flows. Version 0.32.0 contains a patch.
