CVE-2025-52921 (GCVE-0-2025-52921)

Vulnerability from cvelistv5 – Published: 2025-06-23 00:00 – Updated: 2025-06-23 13:51
VLAI
Summary
In Innoshop through 0.4.1, an authenticated attacker could exploit the File Manager functions in the admin panel to achieve code execution on the server, by uploading a crafted file and then renaming it to have a .php extension by using the Rename Function. This bypasses the initial check that uploaded files are image files. The application relies on frontend checks to restrict the administrator from changing the extension of uploaded files to .php. This restriction is easily bypassed with any proxy tool (e.g., BurpSuite). Once the attacker renames the file, and gives it the .php extension, a GET request can be used to trigger the execution of code on the server.

CVE-2025-52968 (GCVE-0-2025-52968)

Vulnerability from cvelistv5 – Published: 2025-06-23 00:00 – Updated: 2025-06-23 16:18 Disputed
VLAI
Summary
xdg-open in xdg-utils through 1.2.1 can send requests containing SameSite=Strict cookies, which can facilitate CSRF. (For example, xdg-open could be modified to, by default, associate x-scheme-handler/https with the execution of a browser with command-line options that arrange for an empty cookie store, although this would add substantial complexity, and would not be considered a desirable or expected behavior by all users.) NOTE: this is disputed because integrations of xdg-open typically do not provide information about whether the xdg-open command and arguments were manually entered by a user, or whether they were the result of a navigation from content in an untrusted origin.

Vulnerability from cvelistv5 – Published: 2025-10-08 00:00 – Updated: 2025-10-08 17:18
VLAI
Summary
Framelink Figma MCP Server before 0.6.3 allows an unauthenticated remote attacker to execute arbitrary operating system commands via a crafted HTTP POST request with shell metacharacters in input that is used by a fetchWithRetry curl command. The vulnerable endpoint fails to properly sanitize user-supplied input, enabling the attacker to inject malicious commands that are executed with the privileges of the MCP process. Exploitation requires network access to the MCP interface.

CVE-2025-56558 (GCVE-0-2025-56558)

Vulnerability from cvelistv5 – Published: 2025-10-29 00:00 – Updated: 2026-01-13 21:16 Exclusively Hosted Service Disputed
VLAI
Summary
The Dyson MQTT server (2022 and possibly later) allows publications and subscriptions by a client that has the correct values of AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, and device serial number, even if a device (such as a Pure Hot+Cool device) has been removed and is not visible in the supported MyDyson app. This could allow an unexpected actor to obtain control and set the room temperature (up to 37 Celsius) if ownership of the device is transferred without wiping the device. NOTE: the Supplier's position is that this is a potential vulnerability that dates back 4 years ago in 2022 and "we are unable to replicate that anymore." Based on the submitted report, in order to leverage this issue, an attacker needs to own a Dyson device with full privileges, sniff for the AWS credentials, and then transfer ownership of that Dyson device to the victim. Even if these steps were successfully accomplished, the attacker only acquires the ability to configure the Dyson device within its safe operating range, and does not acquire the ability to execute code on the device or obtain sensitive information.

CVE-2025-59033 (GCVE-0-2025-59033)

Vulnerability from cvelistv5 – Published: 2025-09-08 00:00 – Updated: 2025-11-17 15:57
VLAI
Summary
The Microsoft vulnerable driver block list is implemented as Windows Defender Application Control (WDAC) policy. Entries that specify only the to-be-signed (TBS) part of the code signer certificate are properly blocked, but entries that specify the signing certificate's TBS hash along with a 'FileAttribRef' qualifier (such as file name or version) may not be blocked, whether hypervisor-protected code integrity (HVCI) is enabled or not. NOTE: The vendor disputes this CVE ID assignment and states that the driver blocklist is intended for use with HVCI.

CVE-2025-62001 (GCVE-0-2025-62001)

Vulnerability from cvelistv5 – Published: 2025-12-18 20:32 – Updated: 2026-01-15 19:51
VLAI
Title
BullWall Ransomware Containment hard-coded folder exclusions
Summary
BullWall Ransomware Containment supports configurable file and directory exclusions such as '$RECYCLE.BIN' to balance monitoring scope and performance. Certain exclusion patterns could allow an authenticated attacker to rename directories in a way that avoids monitoring. Fixed in 4.6.1.14 and 5.0.0.42, which remove hardcoded exclusion behavior and exposes exclusion handling as configurable settings.
