On April 18th 2025, Microsoft announced Exchange Server Security Changes for Hybrid Deployments and accompanying non-security Hot Fix. Microsoft made these changes in the general interest of improving the security of hybrid Exchange deployments. Following further investigation, Microsoft identified specific security implications tied to the guidance and configuration steps outlined in the April announcement. Microsoft is issuing CVE-2025-53786 to document a vulnerability that is addressed by taking the steps documented with the April 18th announcement. Microsoft strongly recommends reading the information, installing the April 2025 (or later) Hot Fix and implementing the changes in your Exchange Server and hybrid environment.
CVAT is an open source interactive video and image annotation tool for computer vision. In versions 1.1.0 through 2.41.0, email verification was not enforced when using Basic HTTP Authentication. As a result, users could create accounts using fake email addresses and use the product as verified users. Additionally, the missing email verification check leaves the system open to bot signups and further usage. CVAT 2.42.0 and later versions contain a fix for the issue. CVAT Enterprise customers have a workaround available; those customers may disable registration to prevent this issue.
HCL IEM is affected by an improper invalidation of access or JWT token vulnerability. A token was not invalidated which may allow attackers to access sensitive data without authorization.
Improper Authentication vulnerability in Samsung Electronics MagicINFO 9 Server allows Authentication Bypass.This issue affects MagicINFO 9 Server: less than 21.1080.0.
Insufficient protection against brute-force and runtime manipulation in the local authentication component in Two App Studio Journey 5.5.6 on iOS allows local attackers to bypass biometric and PIN-based access control via repeated PIN attempts or dynamic code injection.
An improper access control vulnerability was found in the EZ Sync Manager of ADM, which allows authenticated users to copy arbitrary files from the server file system into their own EZSync folder. The vulnerability is due to a lack of authorization checks on the file parameter of the HTTP request. Attackers can exploit this flaw to access files outside their authorized scope, provided the file has readable permissions for other users on the underlying OS. This can lead to unauthorized exposure of sensitive data.
Affected products and versions include: from ADM 4.1.0 to ADM 4.3.3.RH61 as well as ADM 5.0.0.RIN1 and earlier.
An attacker of Secrets Manager, Self-Hosted installations that route traffic from Secrets Manager to AWS through a misconfigured network device can reroute authentication requests to a malicious server under the attacker’s control. CyberArk believes there to be very few installations where this issue can be actively exploited, though Secrets Manager, Self-Hosted (formerly Conjur Enterprise) prior to versions 13.5.1 and 13.6.1 and Conjur OSS prior to version 1.22.1 may be affected. Conjur OSS version 1.22.1 and Secrets Manager, Self-Hosted versions 13.5.1 and 13.6.1 fix the issue.
Vulnerabilities* in ActADUR local server product, developed and maintained by ProTNS, allows Remote Code Inclusion on host systems.
* vulnerabilities:
*
Improper Neutralization of Special Elements used in a Command ('Command Injection')
* Use of Hard-coded Credentials
* Improper Authentication
* Binding to an Unrestricted IP Address
The vulnerability has been rated as critical.This issue affects ActADUR: from v2.0.1.9 before v2.0.2.0., hence updating to version v2.0.2.0.or above is required.
In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade.
Only configurations using "SSLEngine optional" to enable TLS upgrades are affected. Users are recommended to upgrade to version 2.4.64, which removes support for TLS upgrade.
Press, a Frappe custom app that runs Frappe Cloud, manages infrastructure, subscription, marketplace, and software-as-a-service (SaaS). Users can circumvent 2FA login for users due to a lack of server side validation for the same. This vulnerability is fixed in commit ddb439f8eb1816010f2ef653a908648b71f9bba8.
Improper Authentication vulnerability in Wikimedia Foundation Mediawiki - CentralAuth Extension allows : Bypass Authentication.This issue affects Mediawiki - CentralAuth Extension: from 1.39.X before 1.39.13, from 1.42.X before 1.42.7, from 1.43.X before 1.43.2.
authentik is an open-source identity provider. After authorizing access to a RAC endpoint, authentik creates a token which is used for a single connection and is sent to the client in the URL. This token is intended to only be valid for the session of the user who authorized the connection, however this check is missing in versions prior to 2025.6.3 and 2025.4.3. When, for example, using RAC during a screenshare, a malicious user could access the same session by copying the URL from the shown browser.authentik 2025.4.3 and 2025.6.3 fix this issue. As a workaround, it is recommended to decrease the duration a token is valid for (in the RAC Provider settings, set Connection expiry to `minutes=5` for example). The maintainers of authentik also recommend enabling the option Delete authorization on disconnect.
Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. A vulnerability present in versions 0.9.10 through 0.9.16 allows a user to authenticate to a Linux host via Himmelblau using an *invalid* Linux Hello PIN, provided the host is offline. While the user gains access to the local system, Single Sign-On (SSO) fails due to the network being down and the inability to issue tokens (due to a failure to unlock the Hello key). The core issue lies in an incorrect assumption within the `acquire_token_by_hello_for_business_key` function: it was expected to return a `TPMFail` error for an invalid Hello key when offline, but instead, a preceding nonce request resulted in a `RequestFailed` error, leading the system to erroneously transition to an offline success state without validating the Hello key unlock. This impacts systems using Himmelblau for authentication when operating in an offline state with Hello PIN authentication enabled. Rocky Linux 8 (and variants) are not affected by this vulnerability. The problem is resolved in Himmelblau version 0.9.17. A workaround is available for users who cannot immediately upgrade. Disabling Hello PIN authentication by setting `enable_hello = false` in `/etc/himmelblau/himmelblau.conf` will mitigate the vulnerability.
Hikka, a Telegram userbot, has vulnerability affects all users on all versions of Hikka. Two scenarios are possible.1. Web interface does not have an authenticated session: attacker can use his own Telegram account to gain RCE to the server by authorizing in the dangling web interface.2. Web interface does have an authenticated session: due to insufficient warning in the authentication message, users were tempted to click "Allow" in the "Allow web application ops" menu. This gave an attacker access not only to remote code execution, but also to Telegram accounts of owners. Scenario number 2 is known to have been exploited in the wild. No known patches are available, but some workarounds are available. Use `--no-web` flag and do not start userbot without it; after authorizing in the web interface, close the port on the server and/or start the userbot with `--no-web` flag; and do not click "Allow" in your helper bot unless it is your explicit action that needs to be allowed.
Hikka is a Telegram userbot. A vulnerability affects all users of versions below 1.6.2, including most of the forks. It allows an unauthenticated attacker to gain access to Telegram account of a victim, as well as full access to the server. The issue is patched in version 1.6.2. No known workarounds are available.
ControlID iDSecure On-premises versions 4.7.48.0 and prior are vulnerable to an improper authentication vulnerability which could allow an attacker to bypass authentication and gain permissions in the product.
