Title
MyBooks: Privilege Escalation via Missing Authorization on Admin Settings Endpoint
Summary
MyBooks is an ebook management web server also known as Talebook. In 3.41.2 and earlier, the AdminSettings.post handler for POST /api/admin/settings in webserver/handlers/admin.py applies the auth decorator but does not check the self.admin_user property, unlike the corresponding GET handler. Any authenticated regular user can therefore overwrite server configuration values including SMTP credentials, OAuth client secrets, storage paths, security feature flags, and autoreload settings. The process_auth_header function in webserver/handlers/base.py also fails to verify the matched account's active flag, allowing a registered but unactivated account to authenticate and reach the vulnerable handler. Exploitation can disclose secrets through configuration access paths, sabotage application behavior, force service restarts, and supply the settings needed for related code-injection attacks. This issue is fixed in version 3.42.0.

Pimcore: Missing Authorization in WebDAV MOVE via unchecked asset move handling
Summary
Pimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.17 (LTS) and 12.3.7, Pimcore's WebDAV asset endpoint exposes a MOVE operation through /asset/webdav{path} without an authentication plugin in bundles/CoreBundle/src/Controller/WebDavController.php, and models/Asset/WebDAV/Tree.php performs asset mutation and deletion through models/Asset.php before checking a current Pimcore user or the rename, delete, create, or publish permissions, allowing unauthorized asset deletion, moves, or overwrites. This issue is fixed in versions 11.5.17 (LTS) and 12.3.7.

Title
Summarize < 0.15.1 Unapproved Browser Automation Execution
Summary
Summarize prior to 0.15.1 contains a missing authorization vulnerability that allows attackers to execute browser automation actions without per-call user approval when the extension automation feature is enabled. Attackers can influence the agent through malicious page or summary content to invoke enabled extension automation tools such as navigation or debugger-backed actions, bypassing the final user approval step when a user interacts with attacker-controlled content.

Title
Summarize < 0.15.1 Path Traversal via slidesDir Parameter
Summary
Summarize prior to 0.15.1 contains a path traversal vulnerability in the /v1/summarize daemon endpoint that allows authenticated callers to write files to arbitrary directories by supplying an absolute path or directory traversal sequence in the slidesDir request parameter. Attackers can exploit this to write slide_*.png and slides.json files to any writable directory and subsequently delete matching files at the specified location through repeat extraction.

Title
SiYuan: Broken access control in SiYuan `/api/tag/getTag` — Reader role can mutate `Conf.Tag.Sort` and persist to disk
Summary
SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, POST /api/tag/getTag is registered with model.CheckAuth only, omitting both model.CheckAdminRole and model.CheckReadonly, despite the handler performing a configuration write that is normally guarded by both. Any authenticated user — including publish-service RoleReader accounts and RoleEditor accounts on a read-only workspace — can call this endpoint with a sort argument to mutate model.Conf.Tag.Sort and trigger model.Conf.Save(), which atomically rewrites the entire workspace conf.json. This vulnerability is fixed in 3.7.0.

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.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
