Descripción técnica

The XRootD project provides a high-performance, fault-tolerant, and secure solution for handling large amounts of data distributed across multiple storage resources. Prior to version 5.9.2, XRootD's rpCheck() function in src/XrdXrootd/XrdXrootdXeq.cc rejects a parent-directory component only when two dots are followed by a slash and does not reject a terminal two-dot component. An unauthenticated attacker can append /.. to an exported path in xrdfs ls or an HTTP PROPFIND request, bypass the all.export directory scope, and cause directory and filename enumeration in the parent directory under oss.localroot. The demonstrated vector does not permit file download or disclose file contents. This issue is fixed in version 5.9.2.

CVE-2026-1205138.2 ALT

—

———The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to file deletion due to insufficient file path validation in the remove_csv_file_after_email_send function in all versions up to, and including, 3.6.2 This makes it possible for unauthenticated attackers to delete files within the wp-content/uploads directory on the server, which can lead to loss of uploaded content. On hardened Apache configurations, deletion of uploads/.htaccess can re-enable PHP execution inside the uploads directory. This attack is only possible when the Save-and-Continue addon is active (EVF_SAVE_AND_CONTINUE_VERSION is defined) and the 'Disable storing entry information' setting is enabled on the target form. Escaping the uploads directory and deleting files in the site root can be possible under rare circumstances.5h CVE-2026-1003867.5 ALT

—

———The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.5.54 via the uacf7_wpcf7_mail_components function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires the PDF Generator addon to be active and an administrator-configured PDF body template to be enabled for the targeted contact form.5h CVE-2026-107246—

—

———The Plesk extension "Site Import" before 1.13.2 does not properly validate domain and session identifiers, allowing path traversal. This lets a non-owner subscription user redirect a privileged backend session into a directory they control, resulting in arbitrary code execution as root.11h CVE-2026-1253856.5 MED

—

———INDOTALENT WHMS before 10.20261109 contains a path traversal vulnerability that allows authenticated users to read arbitrary files via the documentName and imageName parameters. Attackers can self-register and supply traversal sequences to GetDocument or GetImage, which use Path.Combine without containment checks, to read files like appsettings.json.12h CVE-2026-1253575.3 MED

—

———Munin munin-httpd 2.99.1 through 2.999.18 contains a path traversal vulnerability in the static file handler of Munin::Master::HTML::handle_request that allows unauthenticated attackers to read files outside the static directory. Attackers can request /static/../<file> to bypass the '/../' substring check and read munin.conf and plugin-conf.d files containing monitored service credentials.12h CVE-2026-86692—

———In apport before 2.37.0, a path traversal vulnerability allows an attacker who can supply a crafted crash report to cause unintended file creation or overwrite outside the intended extraction directory when the report is processed with apport-unpack. The key-name validation added for CVE-2026-77113 does not cover base64-encoded keys skipped by ProblemReport.load(binary=False), and ProblemReport.extract_keys() writes them to a file path built from the key without validation. This allows an attacker to create or overwrite arbitrary files writable by the invoking user, such as .bashrc or .profile, gaining persistence or code execution in that user's context.14h
