A vulnerability in the endpoint group (EPG) contract functionality of Cisco Nexus 9000 Series Fabric Switches in ACI Mode could allow an unauthenticated, remote attacker to bypass configured EPG contracts. This vulnerability is due to an improper control with EPG contracts. An attacker could exploit this vulnerability by sending IPv4 or IPv6 packets using UDP source and destination ports that are assigned to DHCP traffic through an affected device. A successful exploit could allow the attacker to bypass EPG contracts on the affected device.Show less

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31 and 6.9.13-56, a missing security-policy check in the CUT encoder allows a crafted local encoding operation to read data that policy should deny and can also cause a crash. This issue is fixed in versions 7.1.2-31 and 6.9.13-56.Show less

MISP contains a defect in its event save workflow that prevents the correlation engine from recalculating correlations when an event's distribution level or sharing group is modified. When a user edits an existing event and changes its distribution or sharing_group_id, the internal before-save hook stored the incoming (new) data rather than the previously persisted values. As a result, the after-save comparison that determines whether a correlation refresh is needed never detected the change, and stale correlations persisted. Security impact: - Stale correlations may continue to expose event data to users in a broader sharing group after the event has been moved to a more restrictive group, resulting in unintended information disclosure. - Conversely, newly relevant correlations may not appear after a distribution widening, degrading the completeness of threat intelligence sharing. Preconditions: - An authenticated user with write access to at least one MISP event. - The user modifies the event's distribution or sharing_group_id field. Affected versions: <2.5.48Show less

Joomla Extension - ordasoft.com - Unauthenticated Destructive CRUD in OrdaSoft Touch Slider < 5.4.6 - modOsTouchSliderHelper::getAjax(), wired through Joomla’s core com_ajax dispatcher, is the single handler behind every data-management operation this module exposes. No call to JFactory::getUser(), authorise(), or a CSRF token check exists anywhere in the handler. Two confirmed impact paths: an unauthenticated GET deletes any slider image by guessable sequential IDs, and an unauthenticated multipart upload with a zip file renames and replaces the entire #__os_touch_slider/#__os_touch_slider_text tables site-wide with attacker-supplied content, with no task parameter even required for the second path.Show less

The CP Media Player WordPress plugin before 1.3.4 does not perform a capability check on its settings-page handler, allowing users with only Contributor-level access to create, modify, duplicate and delete the site-wide media player configurations and change a CP Media Player WordPress plugin before 1.3.4 option that should require administrator access.Show less

The Frontend Dashboard WordPress plugin before 3.0.0 does not perform a capability check in one of its AJAX actions, allowing authenticated users with low privileges, such as subscribers, to delete the Frontend Dashboard WordPress plugin before 3.0.0's configured profile and post form fields.Show less

Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by scaffolder action input authorization bypass. An authenticated user with access to affected Scaffolder templates could bypass configured action restrictions. Depending on integration credentials, this could grant unauthorized access to repositories and related source-control resources. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.Show less

An improper access control vulnerability exists in the Android client application for HPE Networking ClearPass Policy Manager, where application functionality may be invoked by untrusted sources. Successful exploitation could allow an unauthenticated remote attacker, with user interaction, to obtain sensitive information from the affected user.Show less

Dell System Update, versions prior to 2.3.0.0, contains an Improper Access Control vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges.Show less

MISP exposes critical infrastructure settings—specifically the Redis host addresses used by the core application, the ZeroMQ plugin, and the SimpleBackgroundJobs plugin—through its web UI and API to site-admin users. The background job workers trust raw Redis job payloads without additional validation. An attacker who obtains a hijacked site-admin session (for example, through a stored cross-site scripting vulnerability) can modify the Redis host settings to point at an attacker-controlled Redis server and then restart the workers. Once the workers connect to the attacker's Redis instance, the attacker can inject malicious job payloads that the workers execute, achieving arbitrary command execution as the worker account. Additionally, the download_attachments_on_load setting, which controls inline attachment rendering, was modifiable through the same interface, allowing a hijacked session to re-enable a feature that could facilitate further client-side attacks. The vulnerability requires site-admin privileges and a prior session-compromise mechanism; it does not require unauthenticated access. The impact is remote code execution in the context of the MISP worker process and potential data exfiltration through the attacker-controlled Redis connection.Show less

Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, the server fails to enforce a field-level access.update restriction on the password field of an authentication collection. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.Show less

Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, the duplicate operation copies values from a source document even when a field is hidden or its access.read or access.create rule rejects that value for the caller. The disableDuplicate setting does not prevent this access-control bypass. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.Show less

The File Media Renamer WordPress plugin through 1.3 does not verify that the requesting user is authorised to modify a given media attachment, allowing any user with file-upload privileges to rename attachments belonging to other users, including administrators, and to corrupt unrelated stored site data that referenced the old file path.Show less

Feehi CMS 2.1.1 is vulnerable to Incorrect Access Control. A low-privilege backend administrator with administrator-update permission can change the password of the built-in super administrator account. The server does not enforce protection for this account, and the update scenario does not require the old password.Show less

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-share-link RPC retrieves a caller-selected share-link ID and verifies only that the caller can edit the parent file. It does not verify that the caller created the share link or has owner or administrator authority, allowing any file editor who knows a share-link UUID to delete links created by other users and revoke external reviewers' access. This issue is fixed in version 2.18.0.Show less
