Title
Kimai before 2.62.0 Authorization Bypass via QuickEntry
Summary
Kimai before 2.62.0 fails to validate create_other_timesheet permission in the QuickEntry controller when creating new timesheets. Authenticated users with view_other_timesheet and edit_other_timesheet permissions can create timesheet records for team members by submitting the QuickEntry form, bypassing authorization checks enforced elsewhere.

Title
GROWI before 8.0.2 Missing Authorization on Attachment Retrieval for Unauthenticated Requests
Summary
GROWI applies its page-viewer permission check to attachment requests only when the request carries an authenticated user. retrieveAttachmentFromIdParam in apps/app/src/server/routes/attachment/get.ts guards the check with a condition requiring the user to be non-null, so a request that carries no session skips the check entirely and the handler returns the file. The routes reached this way, /attachment/:id and /download/:id, take the attachment identifier from the path, so an unauthenticated caller who has an attachment identifier receives the file regardless of whether the page owning it is private and regardless of whether that caller would be permitted to view the page. Identifiers can be retained by a user whose access was later removed, or recovered from anywhere the identifier was previously exposed. Version 8.0.2 runs the check for authenticated and unauthenticated requests alike, skipping it only where a valid share link has already bound the requested file to that link's page.

The routes reached this way, /attachment/:id and /download/:id, take the attachment identifier from the path, so an unauthenticated caller who has an attachment identifier receives the file regardless of whether the page owning it is private and regardless of whether that caller would be permitted to view the page. Identifiers can be retained by a user whose access was later removed, or recovered from anywhere the identifier was previously exposed. Version 8.0.2 runs the check for authenticated and unauthenticated requests alike, skipping it only where a valid share link has already bound the requested file to that link\u0027s page."

Title
Apache ZooKeeper: Missing ACL check on deleteContainer opcode allows unauthorized deletion of any empty persistent/container znode
Summary
The `deleteContainer` opcode (0x14/20) is processed without verifying the caller's ACL permissions, allowing any authenticated client to delete specific znodes in the data tree regardless of the ACL restrictions on the znode or its parent. This opcode is considered internal-only and the official client doesn't have API for it, but a client that can open a plain TCP session on the ZooKeeper client port (2181 by default) - with NO authentication and NO ACL permissions - can delete any empty persistent znode (including regular persistent nodes, container nodes, and TTL nodes) by issuing the raw protocol OpCode deleteContainer (20). The deleteContainer request path completely skips both the session check and the DELETE ACL check that are enforced by the regular delete (OpCode 2) path. This is an authorization bypass / ACL enforcement bug. This issue affects Apache ZooKeeper: from 3.9.0 through 3.9.5, from 3.8.0 through 3.8.6. Users are recommended to upgrade to version 3.9.6 or 3.8.7, which fixes the issue.

CVE-2026-79920 (GCVE-0-2026-79920)

Title
Ajenti: Privilege escalation to root via unauthenticated/unauthorized plugin install task
Summary
Ajenti is a Linux & BSD modular server admin panel. Prior to version 2.2.16, any authenticated user can call /api/core/tasks/start to enqueue InstallPlugin, UnInstallPlugin, or UpgradeAll from plugins/plugins/tasks.py without plugin-management authorization. InstallPlugin and UnInstallPlugin construct a pip package specification from unvalidated name and version fields, and the task worker invokes pip while running as root. A low-privileged user can therefore select or manipulate a package installed with root privileges and can install, remove, or upgrade plugins without administrative permission, resulting in root code execution and full host compromise. This issue is fixed in version 2.2.16.

Title
Termix: Authenticated users can read other users' host status and clear global SSH connections
Summary
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.8.0 until 2.5.1, authenticated Termix users can access the server-stats API without per-host authorization. GET /status returns statuses for hosts the requester cannot access, GET /status/:id accepts an attacker-supplied numeric host identifier, and POST /clear-connections permits a regular user to clear the global SSH connection pool. The affected src/backend/ssh/server-stats.ts routes expose host online or offline state and lastChecked timestamps and can disrupt other users' active sessions or pooled connections. Unauthenticated requests remain blocked, but authentication alone does not preserve tenant isolation. This issue is fixed in version 2.5.1.

Title
MCPHub: Authenticated non-admin user achieves RCE via POST /api/servers (missing authorization on stdio command/args)
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 0.12.15, the POST /api/servers and PUT /api/servers/:name endpoints in MCPHub create/update MCP server configurations and then immediately spawn the configured stdio process via child_process.spawn. Authentication is required, but there is no authorization check restricting these endpoints to admins, and there is no allowlist/sanitization on the command and args fields. As a result, any authenticated non-admin user can submit a server configuration with command:"/bin/sh" (or any other binary) and arbitrary args, causing MCPHub to execute the attacker-controlled process as the MCPHub server's OS user (commonly root in the published Docker image and in npx/systemd deployments). This issue has been patched in version 0.12.15.

Title
MCPHub: Missing Authorization on Built-in Prompt & Resource CRUD (Unauthorized Tampering of Globally-Served Templates/Resources)
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.32, the built-in prompt and resource controllers perform no role checking. The mutating POST/PUT /api/prompts* and POST/PUT /api/resources* routes are attached to the authenticated router with no admin gate, and the handlers never read req.user. The DAO singletons they write are consulted first — ahead of any connected MCP server — for every session in handleGetPromptRequest / handleReadResourceRequest. A non-admin can therefore create, overwrite, and shadow global prompt templates and resources that all other users are served. The scored impact is the unauthorized integrity violation (creation/tampering/shadowing of globally-served records); stored prompt injection into other users' LLM sessions is a downstream consequence of that tampering. This issue has been patched in version 1.0.32.

MCPHub: Missing Authorization on `PUT /api/system-config` Lets Any Non-Admin Rewrite Global Security Configuration
Summary
MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.29, MCPHub's PUT /api/system-config endpoint (handler updateSystemConfig) performs no authorization check. It is protected only by the app-wide authentication middleware and a rate limiter — it never inspects req.user.isAdmin. This issue has been patched in version 1.0.29.

Title
Ech0 before 4.4.3 Authentication Bypass via Comment Panel
Summary
Ech0 before 4.4.3 fails to enforce scope-based authorization on nine comment panel admin endpoints, allowing access tokens with minimal scopes to perform full comment moderation operations. Attackers with a limited-scope access token can list, approve, reject, delete comments, and modify comment system settings by directly accessing the unprotected panel endpoints.

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.
