| CVE-2026-81866 | 1 Apache | 1 Nifi | 2026-09-21 | 4.3 Medium |
| Apache NiFi 2.9.0 through 2.11.0 provide Connector configuration update and verification REST API methods that do not enforce authorization checking on Assets and Secrets referenced in proposed configuration. Updating or verifying a Connector configuration step can apply Asset and Secret references, but framework authorization was limited to write privileges on the Connector itself. As a result of the missing authorization, an authenticated user authorized to modify a Connector, but not authorized to read a referenced Parameter Provider, could apply Secret values backed by that Parameter Provider. The same methods also accepted Asset identifiers without verifying that the Asset belonged to the Connector being configured. Apache NiFi installations that do not implement different levels of authorization across Connectors and Parameter Providers are not subject to this vulnerability, because the framework enforces write permissions on the Connector as the security boundary. Upgrading to Apache NiFi 2.12.0 is the recommended mitigation, which authorizes read access to referenced Parameter Providers and verifies Connector ownership of referenced Assets during configuration update and verification. | ||||
| CVE-2026-94401 | 2026-09-21 | N/A | ||
| MISP has a file-handling vulnerability that could let certain authenticated users make the server read files or access internal network services. When importing an XML file, MISP did not properly verify that the uploaded content was actually XML. Because of this, a user with permission to modify data could upload a file containing a local file path or a web address instead. If a local file path was supplied, MISP could read that file from the server. If a URL was supplied, MISP could make a request to that address, including systems that may only be reachable from inside the organization’s network. The vulnerability could therefore expose sensitive local files and allow unauthorized requests to internal services. Exploitation required a valid MISP account with modify permissions, but no additional user interaction was needed. Version affected: <2.5.47 | ||||

| CVE-2026-94372 | 1 Misp | 1 Misp | 2026-09-21 | N/A |
| MISP contains a stored cross-site scripting (XSS) vulnerability in the default theme's Galaxies index page. When a MISP instance detects unknown custom or default galaxy clusters during synchronization, it renders sample tag names in an informational notice directed at site administrators. In the default theme, these sample tag names were inserted into the HTML output without HTML-entity encoding. A user with tag-editor privileges could craft a malicious misp-galaxy tag containing arbitrary script. When a site administrator subsequently viewed the Galaxies index page, the crafted tag content was interpreted as executable markup in the administrator's browser session, enabling the attacker to read session data, perform actions on behalf of the administrator, or otherwise compromise the administrator's browser context. The Overmind theme already applied HTML escaping to the same values and was not affected. The vulnerability requires the attacker to possess tag-editor-level access to create the crafted tag and requires the victim (a site administrator) to view the Galaxies index page in the default theme. The impact is limited to the administrator's browser session and does not directly compromise the MISP server process. Version affected: <2.5.47 | ||||
| CVE-2026-94373 | 1 Misp | 1 Misp | 2026-09-21 | N/A |
| MISP contains a DOM-based cross-site scripting (XSS) vulnerability in the contextual menu JavaScript component. The ContextualMenu class populates HTML <option> elements by assigning user-controllable values to the innerHTML property. Because innerHTML parses and renders HTML markup, any untrusted string supplied as the option text (value.text or value) is interpreted as live DOM content rather than plain text. An attacker who can influence the data rendered in the contextual menu can inject arbitrary HTML or JavaScript that executes in the victim's browser within the MISP application origin. This may allow session hijacking, data exfiltration, or unauthorized actions performed on behalf of the authenticated user. Version affected: <2.5.47 | ||||
| CVE-2026-94374 | 1 Misp | 1 Misp | 2026-09-21 | N/A |
| MISP contains an insecure direct object reference vulnerability in the processModuleResultsData method of the Event model. When processing module results, the code iterates over EventReport entries supplied in the resolved data and saves each one. Unlike the adjacent attribute and object processing loops, the report loop did not unset the client-supplied 'id' field before calling save(). Because the MISP EventReport model's create() method does not strip the id field, an authenticated user with permission to submit module results could include an 'id' value referencing an existing report belonging to a different event. Upon save(), the ORM would update that existing row rather than insert a new one, allowing the attacker to - read the content of another event's report by reparenting it into their own event - overwrite the report's fields with attacker-controlled data - change the report's event_id to redirect ownership. This constitutes an authorization bypass through a user-controlled key, enabling cross-event data disclosure and integrity compromise. The vulnerability requires an authenticated session with the ability to invoke module result processing on an event. Version affected: <2.5.47 | ||||
| CVE-2026-94379 | 1 Misp | 1 Misp | 2026-09-21 | N/A |
| The login() function in MISP's UsersController.php contained insufficient HTTP method validation for several security-critical code paths. The original code used an allowlist approach, checking only for specific HTTP methods (POST and PUT) before enforcing bruteforce protection, email one-time-password (OTP) verification, and login-failure logging. Because the checks were not exhaustive, an unauthenticated attacker could issue login requests using other HTTP methods and bypass all three security controls simultaneously. Specifically: - the bruteforce blocklisting check and attempt counter were skipped, allowing unlimited credential-guessing attempts without being rate-limited or blocked - the email OTP two-factor authentication step was skipped, defeating the second factor of authentication - login-failure events were neither logged nor counted, removing the audit trail and the mechanism that would normally trigger a blocklist entry. The security impact is the effective disabling of brute-force protection and multi-factor authentication for any attacker who can craft an HTTP request with a non-POST/PUT method to the login endpoint, potentially leading to credential compromise and unauthorized access to the MISP instance. Version affected: <2.5.47 | ||||

| CVE-2026-94394 | 2026-09-21 | N/A | ||
| When a regular user adds a reference between objects or attributes, MISP checks whether the user can access the overall event, but it does not always check whether the individual pieces of data are also allowed for that user. Because of this, someone who can view an event could potentially access attributes or objects inside that event that were meant to be restricted to a specific sharing group or distribution level. The vulnerability affects authenticated users who are not site administrators and who already have access to an event containing more restricted data. The main impact is that users may be able to view sensitive attribute values, object details, or related object data that they should not normally be allowed to see. | ||||
| CVE-2024-20479 | 1 Cisco | 1 Identity Services Engine | 2026-09-21 | 4.8 Medium |
| A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct an XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have Admin privileges on an affected device. | ||||
| CVE-2026-91867 | 2026-09-21 | N/A | ||
| When Neethi fetches a remote policy reference, it only limits the time per read, not the whole transfer, so a server that trickles bytes slowly can keep the fetch alive indefinitely and tie up the calling thread (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue. | ||||
