Vault and Vault Enterprise ("Vault") are vulnerable to an unauthenticated denial of service when processing JSON payloads. This occurs due to a regression from a previous fix for [+HCSEC-2025-24+|https://discuss.hashicorp.com/t/hcsec-2025-24-vault-denial-of-service-though-complex-json-payloads/76393]  which allowed for processing JSON payloads before applying rate limits. This vulnerability, CVE-2025-12044, is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.16.27, 1.19.11, 1.20.5, and 1.21.0.

Vault and Vault Enterprise's ("Vault") AWS Auth method may be susceptible to authentication bypass if the role of the configured bound_principal_iam is the same across AWS accounts, or uses a wildcard. This vulnerability is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.21.0, 1.20.5, 1.19.11, and 1.16.27.

Self Cross-site scripting (XSS) vulnerability on the edit Knowledge Base article page in Liferay Portal 7.4.0 through 7.4.3.101, and older unsupported versions, and Liferay DXP 2023.Q3.1 through 2023.Q3.5, 7.4 GA through update 92, and older unsupported versions allows remote attackers to inject arbitrary web script or HTML via a crafted payload injected into an attachment's filename.

A reflected cross-site scripting (XSS) vulnerability in MCMS v6.0.1 allows attackers to execute arbitrary Javascript in the context of a user's browser via a crafted payload.

### Impact Prototype pollution vulnerability in merge(). If application code calls `rollbar.configure()` with untrusted input, prototype pollution is possible. ### Patches Fixed in 2.26.5 and 3.0.0-beta5. ### Workarounds Ensure that values passed to `rollbar.configure()` do not contain untrusted input. ### References Fixed in https://github.com/rollbar/rollbar.js/pull/1394 (2.26.x) and https://github.com/rollbar/rollbar.js/pull/1390 (3.x)

A Magento bug called SessionReaper is doing the rounds, and researchers warn it’s letting attackers hijack real shopping sessions.

### Impact **Development mode only**. Kottster contains a pre-authentication remote code execution (RCE) vulnerability when running in development mode. The vulnerability combines two issues: 1. The `initApp` action can be called repeatedly without checking if the app is already initialized, allowing attackers to create a new root admin account and obtain a JWT token 2. The `installPackagesForDataSource` action uses unescaped command arguments, enabling command injection An attacker with access to a locally running development instance can chain these vulnerabilities to: - Reinitialize the application and receive a JWT token for a new root account - Use this token to authenticate - Execute arbitrary system commands through `installPackagesForDataSource` **Production deployments were never affected.** ### Patches Fixed in [v3.3.2](https://github.com/kottster/kottster/releases/tag/v3.3.2). Specifically, `@kottster/server` [v3.3.2](https://www.npmjs.com/package/@kottster/server/v/3...
