Sep 10, 2026WP BackItUp Community Edition: Directory TraversalCVE-2026-18386 · WordPress plugins & themes · reported by WordfenceMedium 4.9
The WP BackItUp Community Edition plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.1.0 via the 'backup_file' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The basename() normalization present in the handler only executes when the traversed target path does not exist, providing no protection against reads of existing files.

Nero BackItUp in the Nero Productline is vulnerable to a path parsing/UI rendering flaw (CWE-22) that, in combination with Windows ShellExecuteW fallback extension resolution, leads to arbitrary code execution when a user clicks a crafted entry. By creating a trailing-dot folder and placing a same-basename script, Nero BackItUp renders the file as a folder icon and then invokes ShellExecuteW, which executes the script via PATHEXT fallback (.COM/.EXE/.BAT/.CMD). The issue affects recent Nero BackItUp product lines (2019-2025 and earlier) and has been acknowledged by the vendor.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
