Improper Control of User-Modifiable Attributes in RES CreateSession API
Unsanitized control of user-modifiable attributes in the session creation component in AWS Research and Engineering Studio (RES) prior to version 2026.03 could allow an authenticated remote user to escalate privileges, assume the virtual desktop host instance profile permissions, and interact with AWS resources and services via a crafted API request. To remediate this issue, users are advised to upgrade to RES version 2026.03 or apply the corresponding mitigation patch to their existing environment.
CVE-2026-34406 Alta · 8.8 CWE-915 31/03/2026
APTRS: Privilege Escalation via Mass Assignment of is_superuser in User Edit Endpoint
APTRS (Automated Penetration Testing Reporting System) is a Python and Django-based automated reporting tool designed for penetration testers and security organizations. Prior to version 2.0.1, the edit_user endpoint (POST /api/auth/edituser/<pk>) allows Any user who can reach that endpoint and submit crafted permission to escalate their own account (or any other account) to superuser by including "is_superuser": true in the request body. The root cause is that CustomUserSerializer explicitly includes is_superuser in its fields list but omits it from read_only_fields, making it a writable field. The edit_user view performs no additional validation to prevent non-superusers from modifying this field. Once is_superuser is set to true, gaining unrestricted access to all application functionality without requiring re-authentication. This issue has been patched in version 2.0.1.
CVE-2026-32742 Média · 4.3 CWE-915 18/03/2026
Parse Server session creation endpoint allows overwriting server-generated session fields
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.17 and 8.6.42, an authenticated user can overwrite server-generated session fields (`sessionToken`, `expiresAt`, `createdWith`) when creating a session object via `POST /classes/_Session`. This allows bypassing the server's session expiration policy by setting an arbitrary far-future expiration date. It also allows setting a predictable session token value. Starting in version 9.6.0-alpha.17 and 8.6.42, the session creation endpoint filters out server-generated fields from user-supplied data, preventing them from being overwritten. As a workaround, add a `beforeSave` trigger on the `_Session` class to validate and reject or strip any user-supplied values for `sessionToken`, `expiresAt`, and `createdWith`.
CVE-2026-29056 Alta · 8.8 CWE-915 17/03/2026
Kanboard's privilege escalation via mass assignment in user invite registration allows any invited user to become admin
Kanboard is project management software focused on Kanban methodology. Prior to 1.2.51, Kanboard's user invite registration endpoint (`UserInviteController::register()`) accepts all POST parameters and passes them to `UserModel::create()` without filtering out the `role` field. An attacker who receives an invite link can inject `role=app-admin` in the registration form to create an administrator account. Version 1.2.51 fixes the issue.
CVE-2026-30822 Alta · 7.7 CWE-915 07/03/2026
Flowise: Mass Assignment in `/api/v1/leads` Endpoint
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.0.13, unauthenticated users can inject arbitrary values into internal database fields when creating leads. This issue has been patched in version 3.0.13.
CVE-2025-15602 Alta · 8.8 CWE-915 06/03/2026
Snipe-IT < 8.3.7 Mass Assignment Vulnerability Leading to Privilege Escalation
Snipe-IT versions prior to 8.3.7 contain sensitive user attributes related to account privileges that are insufficiently protected against mass assignment. An authenticated, low-privileged user can craft a malicious API request to modify restricted fields of another user account, including the Super Admin account. By changing the email address of the Super Admin and triggering a password reset, an attacker can fully take over the Super Admin account, resulting in complete administrative control of the Snipe-IT instance.
CVE-2026-28219 Média · 4.3 CWE-915 26/02/2026
Privilege Escalation via Mass Assignment Allows Regular Users to Set Topics as Global Banners
Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, an improper authorization check in the topic management logic allows authenticated users to modify privileged attributes of their topics. By manipulating specific parameters in a PUT or POST request, a regular user can elevate a topic’s status to a site-wide notice or banner, bypassing intended administrative restrictions. Versions 2025.12.2, 2026.1.1, and 2026.2.0 patch the issue. There are no practical workarounds to prevent this behavior other than applying the security patch. Administrators concerned about unauthorized promotions should audit recent changes to site banners and global notices until the fix is deployed.
CVE-2026-27125 Média · 6.8 CWE-915 20/02/2026
Svelte SSR attribute spreading includes inherited properties from prototype chain
svelte performance oriented web framework. Prior to 5.51.5, in server-side rendering, attribute spreading on elements (e.g. <div {...attrs}>) enumerates inherited properties from the object's prototype chain rather than only own properties. In environments where Object.prototype has already been polluted — a precondition outside of Svelte's control — this can cause unexpected attributes to appear in SSR output or cause SSR to throw errors. Client-side rendering is not affected. This vulnerability is fixed in 5.51.5.
CVE-2026-24140 Média · 5.3 CWE-915 23/01/2026
MyTube has Mass Assignment via Settings Management
MyTube is a self-hosted downloader and player for several video websites. Versions 1.7.78 and below have a Mass Assignment vulnerability in the settings management functionality due to insufficient input validation. The application's saveSettings() function accepts arbitrary key-value pairs without validating property names against allowed settings. The function uses Record<string, any> as input type and iterates over all entries using Object.entries() without filtering unauthorized properties. Any field sent by the attacker is directly persisted to the database, regardless of whether it corresponds to a legitimate application setting. This issue has been fixed in version 1.7.78.
CVE-2026-22814 Alta · 8.2 CWE-915 13/01/2026
Mass Assignment in AdonisJS Lucid Allows Overwriting Internal ORM State
@adonisjs/lucid is an SQL ORM for AdonisJS built on top of Knex. Prior to 21.8.2 and 22.0.0-next.6, there is a Mass Assignment vulnerability in AdonisJS Lucid which may allow a remote attacker who can influence data that is passed into Lucid model assignments to overwrite the internal ORM state. This may lead to logic bypasses and unauthorized record modification within a table or model. This affects @adonisjs/lucid through version 21.8.1 and 22.x pre-release versions prior to 22.0.0-next.6. This has been patched in @adonisjs/lucid versions 21.8.2 and 22.0.0-next.6.
CVE-2026-21695 Média · 4.3 CWE-915 07/01/2026
Titra API Contains Mass Assignment Vulnerability
Titra is open source project time tracking software. In versions 0.99.49 and below, an API has a Mass Assignment vulnerability which allows authenticated users to inject arbitrary fields into time entries, bypassing business logic controls via the customfields parameter. The affected endpoint uses the JavaScript spread operator (...customfields) to merge user-controlled input directly into the database document. While customfields is validated as an Object type, there is no validation of which keys are permitted inside that object. This allows attackers to overwrite protected fields such as userId, hours, and state. The issue is fixed in version 0.99.50.
CVE-2025-9315 Média · 6.3 CWE-915 10/12/2025
Unauthenticated Device Registration Vulnerability in MXsecurity Series
An unauthenticated device registration vulnerability, caused by Improperly Controlled Modification of Dynamically-Determined Object Attributes, has been identified in the MXsecurity Series. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted JSON payload to the device's registration endpoint /api/v1/devices/register, allowing the attacker to register unauthorized devices without authentication. Although exploiting this vulnerability has limited modification of data, there is no impact to the confidentiality and availability of the affected device, as well as no loss of confidentiality, integrity, and availability within any subsequent systems.

CVE-2025-7104 Alta · 7.5 CWE-915 29/09/2025
Mass Assignment in danny-avila/librechat
A mass assignment vulnerability exists in danny-avila/librechat, affecting all versions. This vulnerability allows attackers to manipulate sensitive fields by automatically binding user-provided data to internal object properties or database fields without proper filtering. As a result, any extra fields in the request body are included in agentData and passed to the database layer, allowing overwriting of any field in the schema, such as author, access_level, isCollaborative, and projectIds. Additionally, the Object.Prototype can be polluted due to the use of Object.assign with spread operators.
CVE-2025-58367 Crítica · 10.0 CWE-915 05/09/2025
DeepDiff is vulnerable to DoS and Remote Code Execution via Delta class pollution
DeepDiff is a project focused on Deep Difference and search of any Python data. Versions 5.0.0 through 8.6.0 are vulnerable to class pollution via the Delta class constructor, and when combined with a gadget available in DeltaDiff, it can lead to Denial of Service and Remote Code Execution (via insecure Pickle deserialization) exploitation. The gadget available in DeepDiff allows `deepdiff.serialization.SAFE_TO_IMPORT` to be modified to allow dangerous classes such as posix.system, and then perform insecure Pickle deserialization via the Delta class. This potentially allows any Python code to be executed, given that the input to Delta is user-controlled. Depending on the application where DeepDiff is used, this can also lead to other vulnerabilities. This is fixed in version 8.6.1.
