Summary description

Qlik Sense contains a path traversal vulnerability that allows a remote, unauthenticated attacker to create an anonymous session by sending maliciously crafted HTTP requests. This anonymous session could allow the attacker to send further requests to unauthorized endpoints.

Required action

Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.

—

———Improper path containment check in ikus060 rdiffweb 7.1.1 allows an authenticated user to cause the browse, restore, history and delete operations to resolve to a path outside the repository being operated on, via a percent-encoded traversal sequence (%2e%2e) in the request path, because the containment check uses a string prefix comparison (startswith) instead of a filesystem path boundary check. The target must be a sibling path whose name begins with the repository path, and the user already hold permissions on it; the issue can mislead a user into operating on, or deleting, data other than the repository displayed3h CVE-2026-937676.5 MED

———The Tainacan plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.3.0 via the 'guid' 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. This vulnerability is exploitable only when the uploads/tainacan directory does not exist on the server, as this condition causes realpath() to return false, collapsing the base path to an empty string and rendering the containment check ineffective.8h CVE-2026-1038967.5 HIG

—

———The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to a limited file write via path traversal in versions up to, and including, 2.34.5 This is due to the OptimizerWebPageCache::get_cache_file_dir() function concatenating raw, unsanitized $_GET parameter names and values into the on-disk cache path, and the cache_content() sink calling mkdir() and file_put_contents() on the result with no realpath containment check — unlike the sibling delete_page_cache(), which does perform one. This makes it possible for unauthenticated attackers to create arbitrary directories (mode 0777, recursively) outside the cache root and write a cached page into them. The write is LIMITED: the filename is always 'source.html', so the extension is fixed, and the content is the rendered page buffer rather than attacker-supplied data. PHP files cannot be written and code execution is not possible; the demonstrated impact is cache poisoning and arbitrary directory creation.8h CVE-2026-1092218.1 HIG

———The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the copy_file function in all versions up to, and including, 4.9.3 This makes it possible for authenticated attackers, with Sales Representative-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 is exploitable by any user holding the plugin-defined import_contacts capability, which is granted by default to the plugin's custom Sales Representative role.9h CVE-2026-1047695.9 MED

—

———The Debloat – Remove Unused CSS, Optimize JS plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.3.0 via the 's' 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. Exploitation requires that the site administrator has enabled the Optimize CSS feature (with the default Inline Google Fonts option active), but once that condition is met the attack is trivially triggered by an unauthenticated visitor with a single crafted GET request to the public search URL.10h CVE-2026-848237.1 HIG

———A flaw was found in WildFly. A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.14h
