Title
Langflow: Authenticated Users Can Read, Modify, and Delete Any Flow via Missing Ownership Check
Summary
Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to version 1.5.1, the `_read_flow` helper in `src/backend/base/langflow/api/v1/flows.py` branched on the `AUTO_LOGIN` setting to decide whether to filter by `user_id`. When `AUTO_LOGIN` was `False` (i.e., authentication was enabled), neither branch enforced an ownership check — the query returned any flow matching the given UUID regardless of who owned it. This allowed any authenticated user to read any other user's flow, including embedded plaintext API keys; modify the logic of another user's AI agents, and/or delete flows belonging to other users. The vulnerability was introduced by the conditional logic that was meant to accommodate public/example flows (those with `user_id = NULL`) under auto-login mode, but inadvertently left the authenticated path without an ownership filter. The fix in version 1.5.1 removes the `AUTO_LOGIN` conditional entirely and unconditionally scopes the query to the requesting user.

Title
act: actions/cache server allows malicious cache injection
Summary
act is a project which allows for local running of github actions. Prior to version 0.2.86, act's built in actions/cache server listens to connections on all interfaces and allows anyone who can connect to it including someone anywhere on the internet to create caches with arbitrary keys and retrieve all existing caches. If they can predict which cache keys will be used by local actions, they can create malicious caches containing whatever files they please most likely allowing arbitrary remote code execution within the docker container. This issue has been patched in version 0.2.86.

Title
Missing authorization checks in Wertheim SafeController Software allow low-privileged users to access restricted functions
Summary
The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains missing authorization checks on multiple web application endpoints. An authenticated attacker with minimal privileges can access endpoints that are not visible in the frontend but remain directly reachable. This allows the attacker to perform restricted actions such as switching the user's branch, uploading arbitrary files, downloading arbitrary files, and viewing details of arbitrary branches.

Title
OpenEMR's Missing Authorization in show-signature.php Allows Portal Patients to Read Staff Signatures
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0.3 have a missing authorization check in `portal/sign/lib/show-signature.php` that allows any authenticated patient portal user to retrieve the drawn signature image of any staff member by supplying an arbitrary `user` value in the POST body. The companion write endpoint (`save-signature.php`) was already hardened against this same issue, but the read endpoint was not updated to match. Version 8.0.0.3 patches the issue.

Title
OpenEMR Missing Authorization on Claim File Download Endpoint
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the billing file-download endpoint `interface/billing/get_claim_file.php` only verifies that the caller has a valid session and CSRF token, but does not check any ACL permissions. This allows any authenticated OpenEMR user — regardless of whether they have billing privileges — to download and permanently delete electronic claim batch files containing protected health information (PHI). Version 8.0.0.3 patches the issue.

Title
OpenEMR Missing ACL Checks on Insurance Company API Routes
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, five insurance company REST API routes are missing the `RestConfig::request_authorization_check()` call that every other data-modifying route in the standard API uses. This allows any authenticated API user to create and modify insurance company records even if their OpenEMR user account does not have administrative ACL permissions. Version 8.0.0.3 patches the issue.

Title
Statamic allows unauthorized content access through missing authorization in its revision controllers
Summary
Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, authenticated Control Panel users could view entry revisions for any collection with revisions enabled, regardless of whether they had the required collection permissions. This bypasses the authorization checks that the main entry controllers enforce, exposing entry field values and blueprint data. Users could also create entry revisions without edit permission, though this only snapshots the existing content state and does not affect published content. This has been fixed in 5.73.16 and 6.7.2.

Title
Junos OS: EX Series: Unauthorized users can execute service-impacting CLI command
Summary
A Missing Authorization vulnerability in the CLI of Juniper Networks Junos OS on EX Series allows a local, authenticated attacker to cause a Denial-of-Service (DoS). On EX2300, EX4000, EX4100, EX4300-MP (Multigigabit) and EX4400 switches, an authenticated, local attacker with no specific permissions or class can execute a specific, privileged CLI 'request' command which will cause complete traffic impact until the system automatically recovers. This issue affects Junos OS on EX2300, EX4000, EX4100, EX4300-MP (Multigigabit) and EX4400: * 23.2R2 versions before 23.2R2-S6, * 23.4 versions before 23.4R2-S8, * 24.2 versions before 24.2R2-S4, * 24.4 versions before 24.4R2-S3, * 25.2 versions before 25.2R2, * 25.4 versions before 25.4R1-S1.

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.
