Title
Grav through 2.0.11 Authentication Bypass via Flex Objects
Summary
The Flex Objects plugin (through 1.4.6, tested with Grav 2.0.11) contains an incorrect authorization vulnerability in its Flex Objects API. FlexApiController::update() checks only the general Flex directory permission and does not apply the additional target/field/super-admin checks enforced by the dedicated Users and Groups API controllers. An authenticated account with api.access, admin.login, and users.update permissions (but without api.users.write or admin.super) can use the generic /api/v1/flex-objects/user-accounts endpoint to change a super administrator's password, or the /api/v1/flex-objects/user-groups endpoint to grant its group admin.super, resulting in full site takeover. Fixed in Flex Objects 1.4.7.

Title
Craft CMS before 5.10.6 Authorization Bypass via structures/move-element
Summary
Craft CMS 5.0.0-RC1 through 5.10.5 contains an incorrect authorization vulnerability. A control-panel user holding only the viewCategories permission (without saveCategories) for a category group can permanently modify that group's category structure — reordering and re-parenting categories — via the structures/move-element action. The structureEditable flag is computed from the view permission rather than the save permission, and the StructuresController authorizes the mutating action on that read-time session grant without a save re-check. Because a category's URI is derived from its position in the structure, moving a category changes its URL and those of its descendants and can corrupt navigation menus built from the category taxonomy. The issue is fixed in 5.10.6.

"value": "Craft CMS 5.0.0-RC1 through 5.10.5 contains an incorrect authorization vulnerability. A control-panel user holding only the viewCategories permission (without saveCategories) for a category group can permanently modify that group\u0027s category structure \u2014 reordering and re-parenting categories \u2014 via the structures/move-element action. The structureEditable flag is computed from the view permission rather than the save permission, and the StructuresController authorizes the mutating action on that read-time session grant without a save re-check. Because a category\u0027s URI is derived from its position in the structure, moving a category changes its URL and those of its descendants and can corrupt navigation menus built from the category taxonomy. The issue is fixed in 5.10.6."

Title
n8n before 2.32.1 Credential Restriction Bypass via AI/LLM Nodes
Summary
n8n versions before 2.32.1 fail to enforce the Allowed HTTP Request Domains allowlist in multiple AI and LLM nodes when user-supplied base or endpoint URLs are configured. Low-privileged workflow editors with use-only access to shared credentials can redirect requests to attacker-controlled hosts and exfiltrate credential secrets for reuse against underlying services.

Title
Incorrect Authorization in Kibana Leading to Unauthorized Deletion of Synthetics Private Locations
Summary
Incorrect Authorization (CWE-863) in Kibana can lead to unauthorized deletion of Synthetics private locations via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). Synthetics private locations can be shared with more than one space, and deleting one removes it from every space it is shared with. The safeguard that prevented the deletion of a private location still in use evaluated only the monitors visible in the requesting user's own space, so monitors that depend on the private location in other spaces were not taken into account. As a result, an authenticated Kibana user holding the Synthetics write privilege in a single space could delete a private location that other spaces still depend on, even where the user has no access to those spaces. Deleting the private location removes the shared configuration and stops the monitors in the other spaces from running, which suppresses the availability monitoring those spaces rely on.

Title
Incorrect Authorization in Kibana Leading to Disclosure of Elastic Defend Endpoint Event Data
Summary
The Elastic Security capability that suggests existing field values while a user authors endpoint policy artifacts queries Elastic Defend event data with Kibana's internal Elasticsearch account instead of the account of the requesting user. Only Kibana feature privileges are verified, and the caller's Elasticsearch index privileges are not. An authenticated user who holds Elastic Security feature privileges but no read access to the Elastic Defend event indices can therefore retrieve field values from that data, including process command line arguments, which commonly contain tokens, credentials, connection strings, and other sensitive operational detail from protected hosts.

Title
Incorrect Authorization in Kibana Agent Builder Leading to Disclosure and Tampering of Private Agents
Summary
Kibana Agent Builder determines whether a caller owns a private agent by comparing a stable user identifier when one is recorded, and falling back to a comparison of the username when it is not. A username is not unique across Elasticsearch authentication realms, so two distinct principals that share a username in different realms are treated as the same owner. This discloses the configuration and instructions of an agent the caller does not own, and allows that agent to be altered or removed.

Title
Incorrect Authorization in Kibana Fleet Leading to Privilege Escalation
Summary
Incorrect Authorization (CWE-863) in Kibana Fleet can lead to privilege escalation via Privilege Abuse (CAPEC-122). Fleet restricts some callers to managing integration policies for one specific integration. When an existing integration policy was updated, that restriction was evaluated against the integration recorded on the stored policy rather than against the replacement integration supplied with the update. An authenticated user holding only the Elastic Defend endpoint policy management privilege was therefore able to convert an endpoint policy they administer into a policy for a different integration, and to supply that integration's configuration at the same time.

Title
Typemill < 2.26.0 Authorization Bypass via Media File Download Route
Summary
Typemill before 2.26.0 contains an authorization bypass vulnerability in the media file download route that allows unauthenticated attackers to access restricted files by submitting path-equivalent URL variants. Attackers can substitute normalized path forms such as dot-slash prefixes, double slashes, or percent-encoded sequences to pass role-based restriction checks while the filesystem resolves the request to the protected file, enabling unauthorized file download without credentials.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
No CAPEC attack patterns related to this CWE.
