CVE-2026-105701 (GCVE-0-2026-105701)

Vulnerability from cvelistv5 – Published: 2026-10-06 06:42 – Updated: 2026-10-06 16:06

Title

ACPT (Premium) <= 2.0.66 - Authenticated (Subscriber+) Remote Code Execution via REST API Email Template

Summary

The ACPT (Premium) plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.0.66 via the render function. This is due to missing capability check on the REST API form creation endpoint and unsandboxed Twig environment rendering email templates. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. The exploit requires the attacker to first create a form with malicious email_settings via the REST API endpoint, then trigger form submission to execute the injected Twig expressions.

Severity

8.8 (High)

CVE-2026-105679 (GCVE-0-2026-105679)

Vulnerability from cvelistv5 – Published: 2026-10-05 19:22 – Updated: 2026-10-05 19:51

Title

Ghost: Stored XSS via File Uploads on Local Storage

Summary

Ghost is a Node.js content management system. From 6.22.1 until 6.64.0, Ghost restricted the content type used to serve uploaded files to prevent browsers from executing them. On sites using the default local storage adapter, this restriction was not applied, so files uploaded by any staff user were served with a content type derived from their file extension. This could be used to host scripts on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.64.0.

Severity

7.3 (High)

Title

Ghost: Stored XSS via Bookmark Card Images

Summary

Ghost is a Node.js content management system. From 5.94.0 until 6.64.0, when creating a bookmark card, Ghost could store non-image files fetched from an external website as bookmark icons or thumbnails. This allowed any staff user, including Contributors, to host arbitrary HTML on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.64.0.

Severity

7.3 (High)

An attacker who convinced an Administrator to import a crafted file could host scripts on the site's domain, possibly resulting in compromise of staff users' admin sessions. This issue is fixed in version 6.67.0.

CVE-2026-105630 (GCVE-0-2026-105630)

Vulnerability from cvelistv5 – Published: 2026-10-05 17:54 – Updated: 2026-10-05 18:41

Title

Plane: Stored XSS via SVG attachment served inline on the application origin (account takeover)

Summary

Plane is an open-source project management tool. Prior to 1.4.0, an authenticated low-privilege workspace member, including a Guest, can upload an image/svg+xml file as a generic or issue attachment. The file retains the attacker-controlled Content-Type, and the asset-download endpoint creates a presigned URL with Content-Disposition: inline. In the default self-hosted MinIO deployment, the asset URL is served from the same origin as the Plane application, allowing embedded SVG JavaScript to execute in the application's security context. A victim, including a workspace administrator, who opens the link can have the session compromised through stored XSS, leading to account takeover. This issue is fixed in 1.4.0.

Severity

8.7 (High)

CVE-2026-105606 (GCVE-0-2026-105606)

Vulnerability from cvelistv5 – Published: 2026-11-02 19:01 – Updated: 2026-11-05 18:01

Title

Joomla Extension - joomlaboat.com - Unauthenticated arbitrary file upload in Custom Tables < 3.7.8

Summary

Joomla Extension - joomlaboat.com - Unauthenticated arbitrary file upload in Custom Tables < 3.7.8 - An unauthenticated attacker can upload a polyglot file with an attacker-controlled extension to the web-accessible tmp directory of any Joomla site that exposes a public Custom Tables submission form, and the stored path is disclosed in the response. By default the uploaded file is served as static content, so the primary impact is an unauthenticated arbitrary file write to a web-accessible directory, which allows hosting of attacker-controlled content (for example phishing or malware pages) under the victim's domain.

Severity

9.5 (Critical)

Mitigation

Architecture and Design

Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.[REF-422] [REF-423]

Mitigation MIT-21

Architecture and Design

Strategy: Enforcement by Conversion

When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.

Mitigation

Architecture and Design

Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically. [REF-423]

Mitigation MIT-5

Implementation

Strategy: Input Validation

Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
For example, limiting filenames to alphanumeric characters can help to restrict the introduction of unintended file extensions.

Mitigation

Architecture and Design

Define a very limited set of allowable extensions and only generate filenames that end in these extensions. Consider the possibility of XSS (CWE-79) before allowing .html or .htm file types.

Mitigation

Implementation

Strategy: Input Validation

Ensure that only one extension is used in the filename. Some web servers, including some versions of Apache, may process files based on inner extensions so that "filename.php.gif" is fed to the PHP interpreter.[REF-422] [REF-423]

Mitigation

Implementation

When running on a web server that supports case-insensitive filenames, perform case-insensitive evaluations of the extensions that are provided.

Mitigation MIT-15

Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation

Implementation

Do not rely exclusively on sanity checks of file contents to ensure that the file is of the expected type and size. It may be possible for an attacker to hide code in some file segments that will still be executed by the server. For example, GIF images may contain a free-form comments field.

Mitigation

Implementation

Do not rely exclusively on the MIME content type or filename attribute when determining how to render a file. Validating the MIME content type and ensuring that it matches the extension is only a partial solution.

Mitigation MIT-17

Architecture and Design Operation

Strategy: Environment Hardening

Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

Mitigation MIT-22

Architecture and Design Operation

Strategy: Sandbox or Jail

Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
Be careful to avoid CWE-243 and other weaknesses related to jails.

CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
