Sep 11, 2026In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol->lcn_empty_bits_per_page is sizCVE-2026-89614 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Critical 9.8
In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol->lcn_empty_bits_per_page is sized from vol->nr_clusters at mount, but ntfs_cluster_alloc() bounds its scan of that array by the size of $Bitmap. Those are independent on-disk quantities and the mount-time check only rejects a $Bitmap that is too small, so an image whose $Bitmap covers more clusters than the volume has lets the scan index past the array. A run whose LCN lies in that gap takes the allocator straight there, since the caller passes the file's own last LCN as its locality hint. KASAN reports a slab out-of-bounds read when a file on such a volume is extended. Clamp the scan to what that array covers, mirroring the max_index calculation the mount-time scan already uses, and reject a decoded LCN at or beyond nr_clusters in the mapping pairs decoder. Conforming volumes are unaffected.

In the Linux kernel, the following vulnerability has been resolved: hugetlb: only adjust reservation during unmapping if mapcount is 0 Since df7a6d1f6405, __unmap_hugepage_range can adjust reservations. In the case of folio mapped in both a parent and a child, if the parent unmaps the range first, the reservation adjustment will result in an underflow of the reserved count. Once the child unmaps the range, the count is restored. Change __unmap_hugepage_range() to check the mapcount before adjusting the reservation.

In the Linux kernel, the following vulnerability has been resolved: ocfs2: cluster: don't sleep while holding o2hb_live_lock in o2hb_region_pin() Patch series "ocfs2: cluster: o2hb_region_pin() fixes", v2. This series fixes three related issues in o2hb_region_pin(), all are from the original implementation in commit: 58a3158a5d17 ("ocfs2/cluster: Pin/unpin o2hb regions"): 1) It is called with o2hb_live_lock (a spinlock) held, but the underlying configfs_depend_item() sleeps (takes inode rwsem and pins the filesystem). This triggers BUG under CONFIG_DEBUG_ATOMIC_SLEEP. 2) When called from the configfs drop_item callback, it creates a lock order inversion: parent inode_lock -> configfs root inode_lock, which can deadlock against subsystem unregistration paths taking root -> parent. 3) If pinning fails partway through o2hb_region_inc_user(), the o2hb_dependent_users counter is leaked and partially-pinned regions are never released, leaving heartbeat regions unprotected on subsequent mounts. Patch 1 reworks o2hb_region_pin() to drop o2hb_live_lock across each sleeping configfs_depend_item() call, using a config_item reference to keep the region alive

Sep 11, 2026Inclusion of functionality from an untrusted control sphere in the Kiro Powers feature in Amazon Kiro IDE before version 0.8.135 might allow remote unauthenticaCVE-2026-89332 · Other software · AWS · reported by ff89ba41-3aa1-4d27-914a-91399e9639e5Medium 6.7
Inclusion of functionality from an untrusted control sphere in the Kiro Powers feature in Amazon Kiro IDE before version 0.8.135 might allow remote unauthenticated actors to obtain sensitive information from a developer workstation. Crafted repository content can cause the agent to modify the workspace settings file, which redirects the Kiro Powers registry request to an actor controlled endpoint and sends workspace data to that endpoint when the Powers panel is opened. To remediate this issue, users should upgrade to Kiro IDE version 0.8.135 or later. Users who opened a project in an earlier version should also rotate any credentials that were present in that project.

Sep 11, 2026Concrete CMS versions 9.0.0 to 9.5.2 is vulnerable to Stored XSS in Board Custom Slot dialog.CVE-2026-81911 · Other software · Concrete CMS · reported by ff5b8ace-8b95-4078-9743-eac1ca5451deMedium 5.8
Concrete CMS versions 9.0.0 to 9.5.2 is vulnerable to Stored XSS in Board Custom Slot dialog. The custom_slot save_template endpoint authorizes the request only against the target board instance (canEditBoardContents()) and then persists the client-supplied selectedTemplateOption[collection] verbatim, rather than rebuilding the content object collection server-side and verifying that each item belongs to the authorized board's data pool. A user with permission to edit the contents of at least one board instance can therefore store a forged summary object whose description field carries a JavaScript-bearing HTML payload. The default summary template renders the description field without output encoding, so the payload executes in the browser of any user who views the affected board slot, including anonymous front-end visitors and dashboard users who preview the resulting rule or block. This can enable session or action takeover and escalation toward an administrator. Concrete CMS versions below 9 do not include the Boards feature and are not affected. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.8 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:P/VC:H/VI

NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. The `nl.nl-portal:documenten-api` package through version 3.0.0 and the `nl.nl-portal:besluiten` package from version 1.5.0 through 3.0.0 lack per-user authorization in GraphQL resolvers, allowing an authenticated user to access other users’ document contents, decisions, audit trails, and decision attachments. Version 3.0.1 contains a patch. As a workaround, block the affected document-content and decision-related GraphQL operations at the API gateway or block their GraphQL types entirely.

Sep 11, 2026NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizationCVE-2026-49462 · Other software · nl-portal · reported by GitHubMedium 5.3
NL Portal Backend Libraries provide backend components for Dutch government portals that interact with residents, customers, suppliers, and partner organizations. In versions up to and including 3.0.0, deployments using the shipped default configuration exposed two GraphQL developer features without requiring authentication: the GraphiQL playground, an interactive UI for issuing GraphQL queries; and schema introspection, which lets a caller download the full description of every query, mutation, type, and argument the API supports. Anyone who could reach the `/graphiql` endpoint could open the playground in a browser, pull the full schema, and use that to map out the API and craft calls against it. By itself this does not leak user data, but it removes the guesswork from attacking the rest of the API and significantly lowers the bar for finding and exploiting other weaknesses. Version 3.0.1 patches the issue. As a workaround, override the two settings in deployed configuration.

Sep 11, 2026Concrete CMS 9 through 9.5.2 is vulnerable to Server-Side Template Injection (SSTI) in Theme Customizer via Unvalidated Style Values.CVE-2026-81910 · Other software · Concrete CMS · reported by ff5b8ace-8b95-4078-9743-eac1ca5451deMedium 5.9
Concrete CMS 9 through 9.5.2 is vulnerable to Server-Side Template Injection (SSTI) in Theme Customizer via Unvalidated Style Values. Values submitted through the customizer (color channels and other style properties handled by ColorStyle and sibling Style classes such as FontFamilyStyle and ImageStyle) are interpolated into server-compiled LESS source without neutralization of LESS syntax, allowing a user with the Theme Customization permission to inject arbitrary LESS directives. By injecting the @import (inline) directive, an attacker can read arbitrary files on the server and reach internal network resources through PHP stream wrappers. The compiled output, including any disclosed file contents, is written to the site's publicly served CSS cache, exposing database credentials, private keys, and other application secrets, and enabling server-side request forgery. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.9 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N.

Concrete CMS 9 through 9.5.2 did not validate an anti-CSRF token in the Boards custom slot dialog controller (concrete/controllers/dialog/board/custom_slot.php) saveTemplate() action. The action created a board_slot_proxy Block and dispatched an AddCustomSlotToBoardCommand against a board instance while gating only on the per-resource canEditBoardContents() permission, so a crafted cross-site request could cause a user holding board-edit permission with an active session to write attacker-chosen slot and template data to a board under their own authority. The state-changing database write completed before any downstream rendering, so the forged request succeeded even when the HTTP response returned a non-200 status. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.3 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Winston Crooker for reporting.

Sep 10, 2026WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 (master, 2026-08-23) contains a cross-site request forgery vulnerability in the CustomizeUseCVE-2026-88871 · Other software · WWBN · reported by VulnCheckMedium 5.3
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 (master, 2026-08-23) contains a cross-site request forgery vulnerability in the CustomizeUser plugin's plugin/CustomizeUser/setSubscribers.json.php endpoint. The script reads users_id and ExtraSubscribers from $_REQUEST and calls User::setExtraSubscribers() without requiring a POST request or a valid CSRF token; autoCSRFGuard() is applied only to POST requests to *.json.php, and the mutation does not pass through ObjectYPT::save()/isUntrustedRequest(), so a cross-origin GET succeeds. An unauthenticated remote attacker who induces a logged-in administrator to load a crafted page (for example an <img> tag pointing at the endpoint) can forge the ExtraSubscribers count displayed on any user's channel. The CustomizeUser plugin is enabled by default, and no patched version was available at the time of reporting.

Sep 9, 2026Checkout Custom Fields Builder for WooCommerce: Authorization bypassCVE-2026-19802 · WordPress plugins & themes · reported by WordfenceMedium 4.3
The Checkout Custom Fields Builder for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to install and activate an arbitrary attacker-hosted plugin, resulting in remote code execution on the server. The required nonce is emitted inline on all admin pages accessible to subscribers when WooCommerce is inactive, meaning any subscriber-level user can harvest it and trigger the exploit without any additional privileges.
