CVE-2026-30845
HighSummary
Wekan to narzędzie kanban typu open source, które w wersjach od 8.31.0 do 8.33 publikuje wszystkie dane integracyjne dla tablicy bez filtrowania pól, co naraża wrażliwe informacje, takie jak adresy URL webhooków i tokeny uwierzytelniające. Publikacje tablic są dostępne dla wszystkich członków tablicy, w tym użytkowników tylko do odczytu oraz niezalogowanych klientów DDP dla publicznych tablic.
Risk Assessment
Narażenie na wyciek tokenów umożliwia atakującym składanie nieautoryzowanych żądań do ujawnionych webhooków, co może prowadzić do nieautoryzowanych działań w zewnętrznych usługach. Organizacje mogą być narażone na poważne incydenty bezpieczeństwa związane z nieautoryzowanym dostępem do danych.
Recommendation
Zaleca się aktualizację Wekan do wersji 8.34 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt dostępu do tablic oraz zrewidować uprawnienia użytkowników.

The TrueBooker – Appointment Booking and Scheduler System plugin for WordPress in all versions up to and including 1.2.3 is vulnerable to authorization bypass. This is due to the plugin not properly verifying that a user is authorized to perform an action.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress in all versions up to and including 3.6.2 is vulnerable to Privilege Escalation. This is due to the plugin not validating that a submitted form ID belongs to a JetFormBuilder form before parsing the referenced post's content as form schema and executing an Advanced Validation server-side callback. This allows unauthenticated attackers to create a new administrator-level user account.

Original NVD description (English source)
Wekan is an open source kanban tool built with Meteor. In versions 8.31.0 through 8.33, the board composite publication in Wekan publishes all integration data for a board without any field filtering, exposing sensitive fields including webhook URLs and authentication tokens to any subscriber. Since board publications are accessible to all board members regardless of their role (including read-only and comment-only users), and even to unauthenticated DDP clients for public boards, any user who can access a board can retrieve its webhook credentials. This token leak allows attackers to make unauthenticated requests to the exposed webhooks, potentially triggering unauthorized actions in connected external services. This issue has been fixed in version 8.34.
