Descripción técnica

An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive whose entries traverse outside the destination directory, causing the extraction process to write files to arbitrary locations with the privileges of that process. This could allow an attacker to inject fabricated records into the system's stored data or tamper with application configuration.

———libks provides foundational support for signalwire C products. Prior to version 2.0.11, `clean_uri()` in libks's HTTP request parser fails to reject URIs whose path has more segments than its internal canonicalization buffer can hold. The canonicalization step silently passes such URIs through with embedded ".." sequences intact, enabling path traversal in any consumer that later joins the URI with a filesystem path. Version 2.0.11 patches the issue.6hCVE-2026-87910—

———When tarfile extracts a link on a system that doesn't support links, it falls back to extracting a member from the archive. In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was ignored. Instead, the member should be skipped if either call returns None.7hCVE-2026-87984—

———An arbitrary file write vulnerability in Mistral Vibe, introduced in version 1.3.4, allows an attacker to create or overwrite files outside the active workspace without user approval. Shell redirection destinations are omitted from permission checks, enabling otherwise allowlisted commands to write to arbitrary paths accessible to the Vibe process.10hCVE-2026-87983—
—
———An arbitrary file read vulnerability in Mistral Vibe, introduced in version 2.6.0, allows an attacker to bypass workspace restrictions using quoted absolute paths in allowlisted shell commands. Improper handling of quotation marks during path validation enables files outside the active workspace to be read without user approval.10hCVE-2026-877276.5 MED

——0The UsersWP plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 1.2.70 via the upload_file_remove() AJAX handler. The plugin stores the value of an account 'file' form field taken directly from $_POST when no real $_FILES upload is provided (process_account() calls uwp_validate_fields() and array_merges the result with the empty output of UsersWP_Files::validate_uploads()). At storage time the value is only checked with validate_file(), which passes any string that does not contain a literal '../'. When the value is later processed by upload_file_remove(), it is again gated with validate_file() and then normalized through uwp_get_file_relative_url(); that helper performs a global str_replace() of the uploads base URL against the stored URL, allowing a crafted URL containing embedded '..<uploads-baseurl>' tokens to collapse into '../../' traversal sequences after the last validation. The transformed value is then appended to the uploads base directory and passed to wp_delete_file() without any canonical containment check. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the affected site's server (including wp-config.7h
