Descrição técnica

FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.5.2-stable and 2.0.1-beta, file read handling in backend/pkg/indexing/indexingFiles.go resolves symbolic links through GetRealPath without confirming that the resolved target remains inside the source root and the user's authorized scope. Download, preview, media, OnlyOffice, and public-share read flows that enable FollowSymlinks can therefore serve an out-of-scope target through a reachable in-scope symlink. An authenticated user with download access can read server-accessible files outside the assigned scope, and a holder of a public share link can do the same without an account when the shared directory exposes such a symlink. This issue is fixed in 1.5.2-stable and 2.0.1-beta.

———Tornado before 6.6 contains a path traversal vulnerability in RequestHandler.static_url() and get_version() that allows attackers to hash files outside static_path using ../ sequences. Attackers controlling input passed to static_url() can obtain SHA-512 hashes of readable files to confirm their existence, or reference /dev/zero to block the event loop indefinitely.11h CVE-2026-1235326.5 MÉD

———gix-fs in gitoxide before 0.24.1 contains a credential disclosure vulnerability that allows remote attackers to capture NTLM credentials by supplying UNC symlink targets in a crafted repository. When a victim checks out the repository on Windows with symlinks enabled, gix_fs::symlink::create calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.11h CVE-2026-1234963.3 BAI

———Vikunja veans before 2.7.1 contains a symlink following vulnerability that allows attackers to make veans init write files outside the repository via crafted repo symlinks. Attackers can ship symlinked .veans.yml, .claude, or .opencode entries to overwrite user files like ~/.bashrc or install veans hooks and plugins globally.11h CVE-2026-1047468.1 ALT

——0The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the stm_listings_ajax_save_user_data function in all versions up to, and including, 1.4.125 This makes it possible for authenticated attackers, with subscriber-level access and above, 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). Although deletion is bounded to wp-content/uploads (preventing removal of wp-config.php), any authenticated Subscriber can trivially exploit this because the required AJAX nonce is printed on every front-end page and the handler's stm_user_avatar_path meta is writable by any logged-in user against their own account.18h CVE-2026-1100046.5 MÉD

——18The wpForo Forum plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the theme_delete function in all versions up to, and including, 3.2.2 This makes it possible for authenticated attackers, with subscriber-level access and above, 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 exploit chain is reachable only on sites where an administrator has created a custom wpForo secondary usergroup with a blank WordPress role and the 'mth' (Manage Themes) capability; on such sites, an attacker can self-register and claim that group via the unguarded wpforo_secondary_groupids[] POST field, bypassing the role-based group filter and gaining theme-management access as a Subscriber.1d CVE-2026-1222655.9 MÉD

——16The Vanquish Upload Files for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.7.13 via the 'vanupfi_file_name' parameter parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The authorization bypass is achieved by supplying a non-existent order ID (e.g., '.pdf'), which causes wc_get_order() to return false and short-circuits the vanupfi_user_can_access_order_files() check, while the is_pdf() branch selector's loose strpos() substring match allows a traversal payload such as '../.pdf/../../../../wp-config.php' to satisfy the PDF branch and be streamed verbatim via readfile().1d
