Threat briefs

An authenticated administrator in Microweber CMS through version 2.0.20 is vulnerable to server-side template injection due to an unsandboxed Twig environment, allowing for arbitrary OS command execution by injecting malicious Twig expressions into mail templates, which are executed automatically upon mail dispatch and can compromise the underlying server.

A critical type confusion vulnerability, CVE-2026-59940, in `seroval.fromJSON()` versions prior to 1.5.3 allows attackers to provide malicious JSON input that misleads Promise control nodes into operating on attacker-controlled values, potentially leading to arbitrary method invocation and remote code execution or server compromise in downstream server frameworks like TanStack Start that deserialize untrusted input with plugins enabled.

An unsafe deserialization vulnerability (CVE-2026-57516) exists in the WebDataset reader of the Ray framework prior to version 2.56.0, allowing remote attackers to achieve arbitrary code execution on Ray remote workers by supplying a malicious tar archive to the `read_webdataset()` function, which then unconditionally calls `pickle.loads()` on .pkl/.pickle entries or `torch.load()` with `weights_only=False` on .pt/.pth entries, executing arbitrary code.

An authorization bypass vulnerability in the `@better-auth/stripe` library allows authenticated users to perform subscription actions (cancel, change plan, restore, open billing portal) against other organizations they are a member of, but not authorized to manage. This occurs due to inconsistent handling of organization IDs between the middleware, which approves the ID from the request query string, and the route handler, which acts on the active organization ID from the session or request body. This flaw enables users to access sensitive billing details and manipulate subscriptions for unintended organizations.

An attacker can perform a pre-account hijacking attack against the `better-auth` library if it uses magic-link or email-OTP plugins alongside open email and password registration and allows unverified accounts. The attacker first registers an account using the victim's email with a password they control. When the legitimate victim later uses a passwordless flow to verify their account, the attacker's pre-set password remains active, granting them persistent, unauthorized access to the victim's account and data, potentially leading to account takeover and user lockout.

The `@better-auth/scim` package is affected by multiple vulnerabilities, including a critical provider-ID collision flaw that allows authenticated users to craft SCIM tokens impersonating existing account providers, leading to unauthorized account access, profile modification, and user deletion, while additional issues include failed user deactivation and email update vulnerabilities bypassing uniqueness checks in versions `1.4.0-beta.27` through `1.6.21` and `1.7.0-beta.0` through `1.7.0-beta.9`.

The Easy Appointments plugin for WordPress, in versions up to and including 3.12.27, is vulnerable to unauthorized data modification due to a missing capability check and nonce verification on the `ea_delete_multiple_connections` AJAX action, allowing authenticated attackers with Contributor-level access or higher to delete arbitrary connection records and disrupt core booking functionality.

A high-severity vulnerability in the `httplib2` Python client library allows a remote attacker to trigger a denial-of-service condition by sending a crafted HTTP response with a small, highly compressed payload that expands excessively upon decompression, causing memory exhaustion or OOM-kill in the client process.

A vulnerability (CVE-2026-55575) in the LiquidJS templating library's `pop` filter, affecting versions up to and including 10.27.0, allows an attacker to bypass the `memoryLimit` accounting, leading to uncontrolled memory allocation and potential denial of service when processing untrusted, large arrays in templates.

An unauthenticated attacker can exploit CVE-2026-55685 in React Router versions 7.0.0 through 7.17.x, when used in Framework Mode applications, to cause a denial-of-service condition by repeatedly accessing the manifest endpoint, leading to heavy server load and slow response times.

A vulnerability, CVE-2026-54673, in `electron-builder`'s `builder-util-runtime` package, specifically in its HTTP redirect handler, allows credential headers like `PRIVATE-TOKEN` (GitLab personal access tokens) and mixed-case `Authorization` tokens to be improperly forwarded to attacker-controlled cross-origin redirect destinations, resulting in credential disclosure and enabling unauthorized access to private GitLab resources.

A high-severity vulnerability (CVE-2026-54672) in the `app-builder-lib` component of Electron Builder allows an attacker to achieve arbitrary code execution by placing a malicious shared library in the current working directory when a vulnerable AppImage is executed, due to an uncontrolled search path element in the `LD_LIBRARY_PATH` environment variable.

Numerous vulnerabilities across MongoDB Core Server and Compass, identified as CVE-2026-13055 through CVE-2026-13078, CVE-2026-14881, and CVE-2026-9737, enable attackers to bypass security policies and induce denial-of-service conditions, necessitating immediate patching.
