CVE-2026-31433
MediumSummary
W jądrze Linuxa naprawiono podatność, która mogła prowadzić do potencjalnego przepełnienia bufora (OOB) w funkcji get_file_all_info() dla złożonych żądań. Problem występował, gdy złożone żądanie składało się z QUERY_DIRECTORY oraz QUERY_INFO (FILE_ALL_INFORMATION), a pierwsza komenda wykorzystywała niemal całą maksymalną wielkość transakcji.
Risk Assessment
Organizacje mogą być narażone na ataki, które wykorzystują tę podatność do nieautoryzowanego dostępu do danych lub destabilizacji systemu. W przypadku wykorzystania tej luki, atakujący może uzyskać dostęp do wrażliwych informacji.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować systemy pod kątem nietypowych działań, które mogą wskazywać na próby wykorzystania tej luki.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.
