CVE-2026-26831
CriticalSummary
Textract w wersjach do 2.5.0 jest podatny na wstrzyknięcie poleceń systemowych poprzez parametr ścieżki pliku w wielu ekstraktorach. Przy przetwarzaniu plików z złośliwymi nazwami plików, filePath jest przekazywane bezpośrednio do child_process.exec() w lib/extractors/doc.js, rtf.js, dxf.js, images.js i lib/util.js bez odpowiedniej sanitizacji.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do wykonania dowolnych poleceń systemowych na serwerze, co stwarza poważne zagrożenie dla bezpieczeństwa organizacji. Atakujący może uzyskać pełną kontrolę nad systemem, co może skutkować utratą danych lub naruszeniem poufności.
Recommendation
Zaleca się aktualizację biblioteki textract do najnowszej wersji, która zawiera poprawki zabezpieczeń. Dodatkowo, należy wdrożyć odpowiednie mechanizmy sanitizacji danych wejściowych, aby zminimalizować ryzyko wstrzyknięcia poleceń.

- 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)
textract through 2.5.0 is vulnerable to OS Command Injection via the file path parameter in multiple extractors. When processing files with malicious filenames, the filePath is passed directly to child_process.exec() in lib/extractors/doc.js, rtf.js, dxf.js, images.js, and lib/util.js with inadequate sanitization
