Title
MISP user edit endpoint mass assignment vulnerability allows unauthorized user account modification
Summary
A mass assignment vulnerability exists in the MISP user edit functionality due to insufficient filtering of user-supplied fields in UsersController::edit(). When processing edit requests, the application accepted a user-controlled User.id value from request data. An authenticated attacker could craft a modified request containing another user identifier, potentially causing updates to be applied to an unintended user account. Depending on the editable fields and the attacker’s privileges, this could allow unauthorized modification of user account attributes and impact account integrity. The issue was addressed by explicitly removing the User.id field from request data before processing the user edit operation.

CVE-2026-10860 (GCVE-0-2026-10860)

Title
MISP CRUDComponent delete validation bypass via operator precedence error
Summary
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.

CVE-2026-10863 (GCVE-0-2026-10863)

Title
MISP User-controlled order parameter in correlations over-correlation endpoint
Summary
A security issue was fixed in the correlations over-correlation endpoint where the order query parameter was accepted from user-controlled named request parameters. This allowed an authenticated user to override the server-defined ordering of over-correlating values. Depending on how the value was processed by the underlying data access layer, this could allow manipulation of database query ordering and potentially expose the application to unsafe query construction. The patch removes order from the set of request-controlled parameters and instead sets the ordering server-side to occurrence desc after processing allowed user parameters. Affected component: app/Controller/CorrelationsController.php, overCorrelations() Security impact: An authenticated attacker could influence the ordering clause used by the over-correlations query. The direct impact appears limited to query manipulation unless further evidence confirms SQL injection or unauthorized data exposure through the manipulated ordering expression.

CVE-2026-10864 (GCVE-0-2026-10864)

Title
MISP Dashboard widget field selection may expose restricted user and organisation data
Summary
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields. For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response. The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields. Impact: An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.

Title
Unauthorized exposure of private galaxies in MISP event template creation
Summary
A visibility control issue in the event template creation workflow allowed non-site-admin users to access private galaxies belonging to other organisations. The event template builder loaded all enabled galaxies without applying organisation or distribution-based access restrictions, potentially exposing private galaxy metadata such as galaxy type and description to users who should not have visibility. The issue has been fixed by restricting galaxy queries for non-site-admin users to galaxies owned by the user’s organisation or galaxies with a non-private distribution setting. Site administrators retain visibility of all enabled galaxies.

Title
MISP Event template importer authorization bypass
Summary
An authorization flaw existed in the MISP Event Template Importer overwrite workflow. When importing an event template in overwrite mode, the application checked whether a matching template already existed but did not verify that the importing user belonged to the organization that owned the existing template. As a result, an authenticated user with access to the template import functionality could forcibly overwrite an event template owned by another organization. Successful exploitation could allow unauthorized modification of another organization’s event template, potentially altering template structure, attributes, or metadata used for subsequent event creation or sharing workflows. Site administrators are not affected by this restriction, as they are explicitly allowed to overwrite templates across organizations. The issue was fixed by enforcing an ownership check before overwrite: non-site-admin users may only overwrite templates owned by their own organization.

Title
Open redirect in MISP dashboard button widget URL handling
Summary
A URL validation flaw in the MISP dashboard button widget allowed a crafted relative-looking URL to be accepted as a local path while being interpreted by browsers as an external URL. The validation rejected URLs containing an explicit scheme, host, or user component, but did not reject paths beginning with a slash followed by a backslash, such as /\example.com. Some browsers normalize backslashes in URLs as forward slashes, which can turn this into a scheme-relative external navigation target. In addition, the generated href concatenated the reconstructed URL with the original URL, increasing the possibility of unsafe or malformed link generation. An attacker able to configure or influence a dashboard button URL could craft a button that appears to point inside the application but redirects users to an attacker-controlled site when clicked. This could be used for phishing, credential theft, or social engineering. The patch fixes the issue by rejecting empty paths and paths starting with /\, and by emitting only the reconstructed validated URL in the anchor href.

CVE-2026-10861 (GCVE-0-2026-10861)

Title
MISP post-login open redirect via pre_login_requested_url
Summary
An open redirect vulnerability existed in MISP UsersController::routeafterlogin() because the value stored in the pre_login_requested_url session key was used as the post-login redirect destination without sufficiently enforcing that it was a local application path. An unauthenticated remote attacker could craft a link that causes a victim to visit a trusted MISP instance and, after successful authentication, be redirected to an attacker-controlled external URL. This could be abused to increase the credibility of phishing attacks, redirect users to counterfeit login pages, or deliver attacker-controlled content from an untrusted domain. CWE-601 describes this weakness as accepting user-controlled input that specifies an external link and using it in a redirect, with phishing as a common consequence. The patch mitigates the issue by decoding and parsing the URL, rejecting URLs with a scheme, host, user component, missing or non-local path, and protocol-relative forms such as //example.com and /\example.com.

CVE-2026-10611 (GCVE-0-2026-10611)

Title
OTP bypass via plugin-based LDAP authentication in MISP when LDAP mixed authentication is enabled
Summary
An authentication bypass vulnerability exists in MISP when LDAP mixed authentication is enabled with OTP enforcement. In deployments configured with LdapAuth.mixedAuth=true and Security.require_otp=true, users authenticated through an authentication plugin, such as LDAP, may have their authenticated session established during the application beforeFilter phase before the normal login flow enforces the OTP challenge. As a result, an attacker with valid primary authentication credentials could bypass the required OTP step by authenticating through the plugin-backed login flow and then directly accessing another application URL instead of completing the OTP verification page. This allows access to the application as the affected user without providing a valid TOTP, HOTP, or email OTP code. The issue affects configurations where plugin-based authentication is enabled and OTP is expected to be mandatory. The fix ensures that OTP requirements are checked immediately after plugin authentication and before the user session is established, redirecting users to the appropriate OTP challenge when required.

Title
CSP Report Endpoint Log Flooding in MISP via Incorrect Size Limit
Summary
The CSP report endpoint in MISP intended to limit logged CSP reports to 1 KB but incorrectly allowed reports up to 1 MB before truncation. On deployments where the endpoint is reachable by untrusted clients, this could allow attackers to generate excessive log volume and contribute to resource exhaustion or log flooding.
