Description

devalue (sveltejs/devalue) 5.8.0 before 5.9.3 contains an unhandled promise rejection in stringifyAsync: when serializing multiple promises, a later promise rejecting before an earlier one settles leaves an internal rejection unhandled, even if the caller catches the returned promise. An attacker able to influence the timing or failure of serialized asynchronous values can terminate the Node.js process.

CVE-2026-123513

Vikunja before 2.7.1 contains a credential exposure vulnerability that allows attackers to steal stored auth tokens by inducing users to switch the frontend API URL. Because checkAndSetApiUrl leaves origin-independent localStorage tokens in place, the bearer token and desktop OAuth refresh token are sent to the attacker's server, enabling account takeover.

CVE-2026-123516

Vikunja before 2.7.1 contains a resource exhaustion vulnerability in the vikunja-file ZIP importer that allows authenticated users to consume CPU and memory by uploading archives with excessive entries. Attackers can upload export ZIPs containing many empty or non-files/ entries that bypass the per-entry caps, forcing scanArchive to process every entry twice.

CVE-2026-123517

Vikunja before 2.7.1 contains an information disclosure vulnerability that allows authenticated users to determine whether private teams exist by calling the team member self-removal endpoint. Attackers can send DELETE requests to /teams/{id}/members/{own username} for arbitrary team ids and use the distinguishable responses to learn if a team exists, is SSO-managed, or has a single member.
