🚨 CVE-2026-80238
Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Execution with Unnecessary Privileges vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to Protection mechanism bypass. This vulnerability is considered critical because a low-privileged operator with SSH access to the SCG host can gain root-level access to the host without requiring a password by leveraging the exposed Docker socket. Additionally, an attacker who compromises a service running within the orchestrator container can access the same socket and escape the container boundary to obtain host-level control. Dell recommends that customers upgrade at the earliest opportunity.

🚨 CVE-2026-86408
Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view().


The vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as:



*
type


*
key_data


*
fingerprint





but did not fetch or authorize the associated parent event first.


The upstream commit explicitly states that cryptographicKeys/view could return a protected event’s signing key to any authenticated user.


The fix adds parent_id and parent_type to the lookup and then enforces authorization through the associated event using fetchSimpleEvent($user, parent_id). If the parent is not an Event, access is limited to site administrators.

🚨 CVE-2026-86417
Affected versions of MISP inconsistently enforced email-address visibility in DashboardsController::listTemplates().


The query always fetched User.email, while redaction happened only inside the non-REST rendering branch. As a result, the same authenticated user who saw redacted data in the normal HTML interface could request the REST/JSON representation and receive template owners’ email addresses without the intended privilege check.


The fix moves the decision to a centralized User::canSeeEmails() authorization helper. Email addresses are now fetched only when the requester is a site administrator or the instance explicitly enables Security.disclose_user_emails. The same helper is also reused by other dashboard widgets to keep email-disclosure policy consistent.

🚨 CVE-2026-86418
Affected versions of MISP expose organisation metadata through the dashboard organisation picker without applying the same visibility restrictions enforced by the normal organisation index and per-organisation view.


The affected endpoint returned fields including:



*
organisation ID;


*
UUID;


*
name.





When Security.hide_organisation_index_from_users was enabled, normal organisation enumeration was restricted, but the dashboard picker still queried all organisations. This allowed authenticated users to discover organisations that should have remained hidden from them.


The fix calls Organisation::createConditions($this->Auth->user()) and appends the resulting ACL conditions to the picker query. Ordinary users are thereby limited to organisations associated with events or proposals they can already see, plus their own organisation, while users with the appropriate sharing-group privilege retain broader visibility.

🚨 CVE-2026-86419
Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality.


In feed processing, redirects were followed without validating the redirect scheme or destination. The original request headers were reused across redirect hops, meaning authentication headers or API credentials configured for a feed could be forwarded to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results to prevent re-resolution after validation.


The TAXII discovery endpoint had a related incomplete SSRF defense. It used gethostbyname() and compared the result against only a few literal addresses. This missed cases including IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and potentially multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator.


Together, these commits harden MISP's outbound URL handling against alternate-address representations, DNS-related bypasses, unsafe redirects, internal-host access, and cross-host credential forwarding.

🚨 CVE-2026-86431
league/commonmark (thephpleague/commonmark) versions >= 2.7.0 and < 2.9.1 contain a cross-site scripting vulnerability in the AttributesExtension. Prefixing an attribute name with a single U+000C form feed byte (e.g. {\x0Conclick="alert(1)"}) bypasses the AttributesHelper::filterAttributes() 'on*' event-handler filter because PHP's trim() does not strip U+000C, causing the attribute to be written verbatim into the output where browsers parse it as a genuine event handler. The same prefix also defeats the allow_unsafe_links check, allowing javascript: URIs through href/src attributes even when allow_unsafe_links is false. Exploitation requires processing untrusted Markdown with the AttributesExtension enabled; the injected script executes when the rendered HTML is viewed. Fixed in 2.9.1.

🚨 CVE-2026-86440
Affected versions of MISP insufficiently validate URLs used by dashboard widgets, particularly the Button widget.


The widget's URL is stored configuration controlled by a user. The previous renderer considered a URL safe if it appeared relative or if its parsed hostname matched the configured MISP hostname. That logic failed to reject dangerous schemes and URL forms that browsers normalize differently from PHP's URL parsing.


As a result, values such as javascript: URLs or backslash-based authority forms could reach the generated anchor's href and execute script or navigate to an attacker-controlled origin when another user interacted with the widget. The upstream commit describes the issue as:


“javascript: and backslash URLs reached the href (stored XSS)”.


The fix routes widget URLs through a shared DashboardURLValidator, rejects dangerous schemes, raw backslashes, control characters, and unauthorized absolute origins, and validates the URL both in the widget handler and renderer.

🚨 CVE-2026-86441
Affected versions of MISP contain inconsistent authorization checks across dashboard widgets that display organisation information.


Several organisation-related widgets did not honor Security.hide_organisation_index_from_users. As a result, authenticated users without the perm_sharing_group permission could enumerate organisations even though the normal organisation index was intentionally hidden from them.


The affected widgets included paths that:



*
returned organisation names and identifiers;


*
could expose additional organisation database fields through JSON export because unrestricted find('all') queries fetched full rows;


*
accepted limit=0 or negative values in a way that could effectively remove the result limit and return the entire organisation table.





A related organisation-contributor leaderboard also ignored the same visibility setting. Its handler counted Event.orgc_id across the entire event table and mapped those IDs to organisation names, revealing every organisation with events regardless of whether the caller could see any of those events. The fix withdraws this widget entirely for users who lack organisation-index visibility.

🚨 CVE-2026-86451
Affected versions of MISP allow authenticated users to retrieve object-reference records by UUID through EventGraphTool::get_reference_data() without first checking whether the requester is authorized to view the object the reference belongs to.


The vulnerable code queried ObjectReference.uuid directly and returned the matching row whenever it existed. Because no parent-object ACL was applied, a user who knew or obtained a reference UUID could retrieve information associated with an object outside their normal access scope. The commit explicitly states that any object reference could be returned by UUID without authorizing its parent object.


The fix retrieves the referenced object's object_id and calls fetchObjectSimple() with the current user. If the user cannot access that parent object, MISP now returns NotFoundException instead of exposing the reference.
