What is CVE-2026-47715?
CVE-2026-47715 is a low-severity missing authorization vulnerability in bugsink, published on 26 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Bugsink is a self-hosted error tracking tool. Prior to 2.2.0, Bugsink issue event pages accept a direct event identifier from the URL and, in affected versions, look up that event without also requiring it to belong to the issue in the URL. This is a project-boundary authorization issue: a logged-in user with access to one project can view another project’s event data through an issue they are allowed to access. The affected views include the stacktrace, details, and breadcrumbs pages for an issue event. This vulnerability is fixed in 2.2.0.
Weakness: CWE-639
