CVE-2026-26065
HighSummary
Calibre to wieloplatformowy menedżer e-booków, który w wersjach 9.2.1 i poniżej jest podatny na atak typu Path Traversal przez czytniki PDB. Umożliwia to zapis dowolnych plików z dowolnym rozszerzeniem i zawartością w miejscach, gdzie użytkownik ma uprawnienia do zapisu.
Risk Assessment
Atakujący może wykorzystać tę podatność do nadpisania istniejących plików, co może prowadzić do wykonania złośliwego kodu oraz do awarii systemu przez uszkodzenie plików.
Recommendation
Zaleca się aktualizację do wersji 9.3.0 lub nowszej, aby usunąć tę podatność.

- CVE-2026-76949Critical
A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
calibre is a cross-platform e-book manager for viewing, converting, editing, and cataloging e-books. Versions 9.2.1 and below are vulnerable to Path Traversal through PDB readers (both 132-byte and 202-byte header variants) that allow arbitrary file writes with arbitrary extension and arbitrary content anywhere the user has write permissions. Files are written in 'wb' mode, silently overwriting existing files. This can lead to potential code execution and Denial of Service through file corruption. This issue has been fixed in version 9.3.0.
