CVE-2026-40569
CriticalSummary
FreeScout to darmowy, samodzielnie hostowany system pomocy technicznej i wspólna skrzynka pocztowa. W wersjach przed 1.8.213 występuje podatność na masowe przypisanie w ustawieniach połączenia skrzynki pocztowej, co pozwala uwierzytelnionemu administratorowi na nadpisanie krytycznych pól modelu Mailbox.
Risk Assessment
Podatność ta może prowadzić do nieautoryzowanego dostępu do wrażliwych danych oraz umożliwić modyfikację ustawień bezpieczeństwa, co stwarza poważne zagrożenie dla organizacji.
Recommendation
Zaleca się aktualizację FreeScout do wersji 1.8.213 lub nowszej oraz przegląd i wzmocnienie walidacji danych w metodach odpowiedzialnych za ustawienia połączenia skrzynki pocztowej.

- CVE-2026-7826Critical
A vulnerability in FalkorDB before 4.18.4 causes a heap-based out-of-bounds read in the BufferSerializerIOv2_ReadBuffer function. A remote attacker who can issue Redis replication commands (e.g., against an instance with no password) can send a crafted RDB stream with a sub-buffer length field exceeding the remaining buffer size. The only bounds check is an ASSERT(), which is compiled out in release builds, so memcpy() reads past the end of the heap allocation.
- CVE-2026-5759Critical
A double free and use-after-free vulnerability in the RdbLoadDeletedNodes function of the RDB graph decoders in FalkorDB before 4.18.1. A remote attacker who can issue Redis replication commands can send a crafted RDB stream where the deleted-nodes buffer length is not a multiple of sizeof(NodeID). The length check relies on ASSERT(), which is compiled out in release builds, so the function continues after freeing the buffer, reading it and freeing it a second time.

Original NVD description (English source)
FreeScout is a free self-hosted help desk and shared mailbox. Versions prior to 1.8.213 have a mass assignment vulnerability in the mailbox connection settings endpoints of FreeScout (`connectionIncomingSave()` at `app/Http/Controllers/MailboxesController.php:468` and `connectionOutgoingSave()` at line 398). Both methods pass `$request->all()` directly to `$mailbox->fill()` without any field allowlisting, allowing an authenticated admin to overwrite any of the 32 fields in the Mailbox model's `$fillable` array -- including security-critical fields that do not belong to the connection settings form, such as `auto_bcc`, `out_server`, `out_password`, `signature`, `auto_reply_enabled`, and `auto_reply_message`. Validation in `connectionIncomingSave()` is entirely commented out, and the validator in `connectionOutgoingSave()` only checks value formats for SMTP fields without stripping extra parameters. An authenticated admin user can exploit this by appending hidden parameters (e.g., `auto_
