CVE-2026-86417

MISP Dashboard Template REST API Exposes Template Owner Email Addresses to Unauthorized Users

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. Version affected: ≤2.5.45

CVE-2026-86419

MISP Insufficient Outbound URL Validation Allows SSRF and Credential Disclosure via Feed Redirects and TAXII Discovery

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. Version affected: ≤2.5.45

CVE-2026-86440

MISP Dashboard Button Widget Allows Stored XSS via Unsafe javascript: and Backslash URLs

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. Version affected: ≤2.5.45

CVE-2026-86441

MISP Dashboard Organisation Widgets Bypass Organisation-Index Restrictions and Expose Hidden Organisation Data

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. Version affected: ≤2.5.45

CVE-2026-86451

MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects

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. Version affected: ≤2.5.45

CVE-2026-86342

MISP Freetext Feed Preview Improper Authorization Exposes Restricted Event and Feed Information

Affected versions of MISP contain improper authorization checks in the freetext feed preview functionality. The preview performed correlation lookups against attributes from events without applying the requesting user's ACL, allowing restricted event correlations and associated event information to be exposed to users who could not otherwise access those events. The vulnerable queries were scoped only by attribute values and deletion status rather than MISP's event, organization, sharing-group, attribute, and object-level access controls. The same preview functionality also returned cross-feed correlation information without properly restricting the feed list to feeds visible to the caller. This exposed metadata for feeds that were not marked lookup_visible; one affected response additionally included the configured feed URL even though that value was not required by the feature. The fixes apply the caller's ACL to attribute correlation searches, remove feed URLs from correlation results, restrict cross-feed results according to feed visibility, and correct host-organization ID comparison so the authorization rules are applied consistently. Version affected: ≤2.5.45
