Mattermost versions 10.4.x <= 10.4.1, 9.11.x <= 9.11.7, 10.3.x <= 10.3.2, 10.2.x <= 10.2.2 fail to properly validate input when patching and duplicating a board, which allows a user to read any arbitrary file on the system via duplicating a specially crafted block in Boards.

Mattermost versions 9.11.x <= 9.11.6, 10.4.x <= 10.4.1 fail to invalidate all active sessions when converting a user to a bot, with allows the converted user to escalate their privileges depending on the permissions granted to the bot.

A list of topics we covered in the week of February 17 to February 23 of 2025

One month into his second term, President Trump's actions to shrink the government through mass layoffs, firings and withholding funds allocated by Congress have thrown federal cybersecurity and consumer protection programs into disarray. At the same time, agencies are battling an ongoing effort by the world's richest man to wrest control over their networks and data.

Plus: Apple turns off end-to-end encrypted iCloud backups in the UK after pressure to install a backdoor, and two spyware apps expose victim data—and the identities of people who installed the apps.

### Summary HTML can be arbitrarily injected into emails from Leantime due to improper neutralization of HTML tags in users' first names. This effectively allows for the creation of phishing emails from a Leantime instance's email address.

### Finding Description Application has functionality for a user to view profile information. It does not have an implemented authorization check for "Host" parameter which allows a user to view profile information of another user by replacing "Host" parameter. ### Impact By exploiting this vulnerability an attacker can able to view profile information (but not anything else or change anything)

### Impact A heap buffer overflow was found in Exiv2 versions v0.28.0 to v0.28.4. Versions prior to v0.28.0, such as v0.27.7, are **not** affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The heap overflow is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `fixiso`. ### Patches The bug is fixed in version v0.28.5. ### References Issue: https://github.com/Exiv2/exiv2/issues/3168 Fix: https://github.com/Exiv2/exiv2/pull/3174 ### For more information Please see our [s...

**CSRF** ### Summary A cross-site request forgery vulnerability allows a remote actor to create an account with Owner privileges. By luring an Owner or Administrator into clicking a button on an attacker-controlled website, a request will be issued, generating an account with the attacker's information and role of their choosing. ### Impact While the likelihood of a successful exploit is low, the impact would be high as the attacker could then gain complete control over the victim's environment.

### Summary A cross-site scripting (XSS) vulnerability has been identified in Leantime. The vulnerability allows an attacker to inject malicious scripts into certain fields, potentially leading to the execution of arbitrary code or unauthorized access to user-sensitive information. The code does not include any validation or sanitization of the $_GET["id"] parameter. As a result, it directly incorporates the user-supplied value into the source path without any checks.
