The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 34.0 and SeaMonkey before 2.31 supports native-interface passing, which allows remote attackers to bypass intended DOM object restrictions via a call to an unspecified method.

Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allow remote attackers to spoof the address bar via a SELECT element with a persistent menu.

Mozilla Firefox before 34.0 and SeaMonkey before 2.31 provide stylesheets with an incorrect primary namespace, which allows remote attackers to bypass intended access restrictions via an XBL binding.

Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 do not ensure that the user approves the fullscreen and pointerlock settings, which allows remote attackers to cause a denial of service (UI outage), or conduct clickjacking or spoofing attacks, via a crafted web site.

If a specific sequence of actions is performed when opening a new tab, the triggering principal associated with the new tab may have been incorrect. The triggering principal is used to calculate many values, including the `Referer` and `Sec-*` headers, meaning there is the potential for incorrect security checks within the browser in addition to incorrect or misleading information sent to remote websites. *This bug only affects Firefox for Android. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 127.

Northern.tech Mender Server before 3.7.11 and 4.x before 4.0.1 has Incorrect Access Control.

FirstUseAuthenticator is a JupyterHub authenticator that helps new users set their password on their first login to JupyterHub. When JupyterHub is used with FirstUseAuthenticator, a vulnerability in versions prior to 1.0.0 allows unauthorized access to any user's account if `create_users=True` and the username is known or guessed. One may upgrade to version 1.0.0 or apply a patch manually to mitigate the vulnerability. For those who cannot upgrade, there is no complete workaround, but a partial mitigation exists. One can disable user creation with `c.FirstUseAuthenticator.create_users = False`, which will only allow login with fully normalized usernames for already existing users prior to jupyterhub-firstuserauthenticator 1.0.0. If any users have never logged in with their normalized username (i.e. lowercase), they will still be vulnerable until a patch or upgrade occurs.

A vulnerability classified as critical was found in Totolink N350RT 9.3.5u.6265. This vulnerability affects unknown code of the file /cgi-bin/cstecgi.cgi of the component Setting Handler. The manipulation leads to improper access controls. The attack can be initiated remotely. It is recommended to upgrade the affected component. VDB-250786 is the identifier assigned to this vulnerability.

To successfully make the attack you must use a username that is not part of the site to bypass the auth checks. For more details and workaround guidance see the referenced GitHub security advisory.

A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sonoma 14.1. An app may gain unauthorized access to Bluetooth.

A vulnerability was found in Metasoft 美特软件 MetaCRM up to 6.4.2. It has been rated as problematic. Affected by this issue is some unknown functionality of the file /env.jsp. The manipulation leads to information disclosure. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

CryptPad is a collaboration suite. Prior to version 2025.3.0, enforcement of Two-Factor Authentication (2FA) in CryptPad can be trivially bypassed, due to weak implementation of access controls. An attacker that compromises a user's credentials can gain access to the victim's account, even if the victim has 2FA set up. This is due to 2FA not being enforced if the path parameter is not 44 characters long, which can be bypassed by simply URL encoding a single character in the path. This issue has been patched in version 2025.3.0.

A vulnerability classified as critical has been found in Weitong Mall 1.0.0. This affects an unknown part of the file /historyList of the component Product History Handler.

An issue was discovered on IROAD Dashcam V devices. It uses an unregistered public domain name as an internal domain, creating a security risk. During analysis, it was found that this domain was not owned by IROAD, allowing an attacker to register it and potentially intercept sensitive device traffic. If the dashcam or related services attempt to resolve this domain over the public Internet instead of locally, it could lead to data exfiltration or man-in-the-middle attacks.
