Mattermost Desktop App versions <=6.1 5.5.13.0 fail to account for attempting to open extremely long URLs in the Mattermost Desktop App which allows a malicious server owner to crash the application via including a script to call window.open on a very large URL. Mattermost Advisory ID: MMSA-2026-00652

Impact: multer versions 2.0.0-alpha.1 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service when using diskStorage. Aborted or malformed multipart uploads leave orphaned partial files on disk because the Readable.pipe() call does not propagate the stream destroy signal to the underlying fs.WriteStream. An attacker can exhaust disk space by triggering many aborted uploads, with no application bug required. Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x prerelease). Both versions track in-flight write streams and clean them up on the abort path. Workarounds: None.

Zephyr's native TCP stack iterates the global connection list in net_tcp_foreach() (subsys/net/ip/tcp.c) using the SYS_SLIST_FOR_EACH_CONTAINER_SAFE macro, which caches a pointer to the next list node. Prior to this fix the function released tcp_lock while invoking the per-connection callback and re-acquired it afterwards. During that window a concurrent tcp_conn_release(), running on the dedicated TCP work-queue thread when a connection's reference count drops to zero (e.g. a remote peer closing or resetting the connection), can remove and k_mem_slab_free() the cached next connection. When the iterator advances it dereferences the freed (and possibly reallocated) slab memory — a use-after-free that can crash the system (denial of service) and, if the slot has been reused, cause the callback to operate on an attacker-influenced object (potential information disclosure or further fault). net_tcp_foreach() is reached in production via the 'net conn' network shell command and via net_tcp_close_all_for_iface() on interface-down; the freeing side is driven by ordinary TCP traffic. The fix moves the connection/context teardown in tcp_conn_release() inside the tcp_lock critical section and keeps tcp_lock held across the callback in net_tcp_foreach(). The defect was introduced with the modern (TCP2) stack in 2020 and affects releases up to and including v4.4.0.

Contributor Cross Site Scripting (XSS) in Elizaibots <= 1.0.2 versions.

Administrator Cross Site Scripting (XSS) in WP Emmet <= 0.3.4 versions.

Mattermost Desktop App versions <=6.1 5.5.13.0 fail to restrict the allow list of domains to which NTLM credentials were forwarded to in the Mattermost Desktop App which allows any user on a server without the image proxy enabled to intercept other users credentials via embedding an image that routes to an external web server. Mattermost Advisory ID: MMSA-2026-00651

Subscriber Broken Access Control in Really Simple SSL <= 9.5.9 versions.

Missing Authorization vulnerability in StylemixThemes MasterStudy LMS Pro allows Accessing Functionality Not Properly Constrained by ACLs. This issue affects MasterStudy LMS Pro: from n/a before 4.7.16.

WordPress More Fields Plugin 2.1 contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized actions by disabling CSRF token validation. Attackers can craft malicious web pages that trick logged-in administrators into adding or deleting custom fields and boxes on the Write/Edit page via POST and GET requests to the options-general.php endpoint.

WordPress Plugin Abtest contains a local file inclusion vulnerability that allows unauthenticated attackers to include arbitrary files by manipulating the action parameter. Attackers can send GET requests to abtest_admin.php with malicious action values to include files from the admin directory and execute arbitrary code.

WordPress Brandfolder plugin version 3.0 and earlier contains a local file inclusion vulnerability in callback.php that allows unauthenticated attackers to include arbitrary files by manipulating the wp_abspath parameter. Attackers can supply path traversal sequences or remote URLs through the wp_abspath parameter to read sensitive files like wp-config.php or execute remote code.

WordPress Dharma Booking 2.28.3 and earlier contains a local file inclusion vulnerability that allows unauthenticated attackers to include arbitrary files by manipulating the gateway parameter. Attackers can supply file paths with directory traversal sequences or null byte injection to the gateway parameter in proccess.php to read sensitive files like configuration and system files.

WordPress IMDb Profile Widget 1.0.8 contains a local file inclusion vulnerability that allows unauthenticated attackers to read arbitrary files by manipulating the url parameter. Attackers can supply directory traversal sequences in GET requests to pic.php to access sensitive files like wp-config.php containing database credentials and configuration data.

WordPress Plugin Photocart Link 1.6 contains a local file inclusion vulnerability that allows unauthenticated attackers to read arbitrary files by exploiting insufficient input validation in decode.php. Attackers can supply base64-encoded file paths in the 'id' parameter to the decode.php endpoint to retrieve sensitive files like wp-config.php containing database credentials and configuration data.

WordPress Lazy Content Slider Plugin 3.4 contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized actions by crafting malicious HTML forms. Attackers can trick authenticated administrators into submitting POST requests to the plugin settings page via lzcs_admin.php to modify plugin configuration parameters like lzcs_color and lzcs_count.

WordPress Booking Calendar Contact Form 1.0.23 contains privilege escalation and stored cross-site scripting vulnerabilities that allow authenticated users to modify plugin options and inject malicious scripts by failing to verify user privileges and sanitize input parameters. Attackers with subscriber-level accounts can inject XSS payloads through parameters like price, name, calendar_language, and email_confirmation_to_user via admin-ajax.php and admin.php endpoints to execute arbitrary JavaScript in administrator browsers.

WordPress CP Polls 1.0.8 contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized actions on behalf of authenticated users. Attackers can craft malicious HTML pages that execute unwanted poll operations when administrators visit the page while logged in.

A flaw was found in Ansible Lightspeed. This vulnerability, related to insufficient session expiration, allows a remote attacker to maintain persistent access to the Ansible Lightspeed instance. If an attacker exfiltrates a valid OAuth (Open Authorization) access token before a user logs out, they can continue to authenticate and access sensitive data. This is because the application fails to invalidate the token on the backend, leaving it valid until its natural expiration. This can lead to unauthorized read access to Ansible resources such as inventories, playbooks, and configuration data.

The Form Builder CP WordPress plugin before 1.2.47 does not properly sanitize a form configuration value before storing it and using it as part of a client-side script execution, allowing authenticated users with Editor-level access and above to perform Stored Cross-Site Scripting attacks against any visitor of a page rendering the affected form, even when the `unfiltered_html` capability is disallowed (e.g. in a multisite network).

The WP Go Maps WordPress plugin before 10.0.10 does not perform any approval-state filtering on its public single-marker REST endpoint, allowing unauthenticated users to retrieve marker records that an administrator has not yet approved for public display, including any PII placed in the address and description fields and the marker's geographic coordinates.

The WP Go Maps WordPress plugin before 10.0.10 does not properly enforce the marker approval filter on the admin-ajax fallback for its datatables route, allowing unauthenticated visitors to retrieve marker records that the site owner has not approved for public display, including their title, category, address and description fields.

A vulnerability was identified in Yealink SIP-T46U 108.86.0.118. Affected by this vulnerability is the function mod_webd.TFTPUploadIperf of the file /api/inner/tftpuploadiperf of the component Web FastCGI Service. The manipulation of the argument ip/port leads to command injection. The attack needs to be initiated within the local network. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
