CVE-2026-86451 MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects
PublishedMediumCVSS 5.3 EPSS 0.27%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 Object...

LowCVSS 2.3 EPSS 0.28%
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_sh...
-
MediumCVSS 5.1 EPSS 0.24%
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 t...

HighCVSS 7.0 EPSS 0.42%
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...

LowCVSS 2.3 EPSS 0.27%
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...

MediumCVSS 5.3 EPSS 0.27%
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...

HighCVSS 7.1 EPSS 0.34%
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 fi...
-
MediumCVSS 5.1 EPSS 0.26%
Affected versions of MISP validate the user-configurable homepage by checking only whether the supplied path begins with /. That check is insufficient because protocol-relative URLs such as //attacker.example also begin with / but resolve to an external origin in browsers. The vu...
-
HighCVSS 7.1 EPSS 0.43%
Affected versions of MISP allow any authenticated user to access TemplatesController::uploadFile() because the ACL entry for templates/uploadFile used the wildcard *. This bypasses the intended role restrictions applied to neighboring template-management operations. The upload ha...
-
MediumCVSS 5.3 EPSS 0.34%
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 e...

CVE-2026-85239 MISP Event Template Definition Validation Bypass Allows Persistent Denial of Service
PublishedHighCVSS 7.1 EPSS 0.45%A vulnerability in MISP's event template handling allowed an authenticated user with permission to create or modify event templates to bypass validation of the template definition field. The EventTemplate::beforeValidate() method only performed semantic validation when the suppli...

CVE-2026-85238 Session Fixation in MISP CustomAuth Authentication Allows Session Hijacking
PublishedHighCVSS 7.6 EPSS 0.34%MISP contains a session fixation vulnerability in the CustomAuth authentication (a custom configuration) flow. When a user was successfully authenticated through CustomAuth, MISP stored the authenticated user identity in the existing session without first rotating the session ide...

HighCVSS 8.6 EPSS 0.46%
A vulnerability in MISP's email-based one-time password (OTP) authentication flow allowed an attacker to perform an unrestricted number of OTP verification attempts. The email_otp() endpoint did not apply brute-force protection when validating submitted OTP values. An attacker wh...

CVE-2026-85236 MISP cullEmptyEvents CSRF Allows Irreversible Deletion of Events via GET Request
PublishedHighCVSS 8.8 EPSS 0.25%A cross-site request forgery (CSRF) vulnerability existed in the cullEmptyEvents action of MISP. The endpoint performed a state-changing and irreversible operation while accepting HTTP GET requests. Because bodyless GET requests are not subject to CakePHP's CSRF validation, an at...

MediumCVSS 5.3 EPSS 0.29%
A persistent unsafe URL injection vulnerability exists in the MISP dashboard ButtonWidget configuration. Dashboard widget URLs were validated only when the widget was rendered and were not validated when the configuration was saved. As a result, an authenticated user able to modi...

HighCVSS 7.6 EPSS 0.27%
MISP contains an improper TLS certificate validation vulnerability in CurlClient. The CurlClient::$verifyPeer property was not explicitly initialized and therefore defaulted to null. When passed to cURL, this value effectively disabled TLS peer verification unless the calling cod...

CVE-2026-56446 Authenticated Remote Code Execution via Arbitrary NDJSON Error Log Path in MISP
PublishedHighCVSS 8.7 EPSS 0.69%MISP allowed a site administrator to configure an arbitrary filesystem path for the NDJSON error log used by JsonLogTool. Because log entries can include attacker-controlled content, an authenticated attacker with site administrator privileges could direct log output to a PHP fil...
