An issue was discovered on Zyxel GS1900 devices with firmware before 2.50(AAHH.0)C0. Through an undocumented sequence of keypresses, undocumented functionality is triggered. A diagnostics shell is triggered via CTRL-ALT-t, which prompts for the password returned by fds_sys_passDebugPasswd_ret(). The firmware contains access control checks that determine if remote users are allowed to access this functionality. The function that performs this check (fds_sys_remoteDebugEnable_ret in libfds.so) always return TRUE with no actual checks performed. The diagnostics menu allows for reading/writing arbitrary registers and various other configuration parameters which are believed to be related to the network interface chips.

An issue was discovered on the Forvia Hella HELLA Driving Recorder DR 820. Bypassing of Device Pairing can occur. The pairing mechanism relies solely on the connecting device's MAC address.

SPID.AspNetCore.Authentication is an AspNetCore Remote Authenticator for SPID. Authentication using Spid and CIE is based on the SAML2 standard which provides two entities: Identity Provider (IDP): the system that authenticates users and provides identity information (SAML affirmation) to the Service Provider, in essence, is responsible for the management of the credentials and identity of users; Service Provider (SP): the system that provides a service to the user and relies on the Identity Provider to authenticate the user, receives SAML assertions from the IdP to grant access to resources. The validation logic of the signature is central as it ensures that you cannot create a SAML response with arbitrary assertions and then impersonate other users. There is no guarantee that the first signature refers to the root object, it follows that if an attacker injects an item signed as the first element, all other signatures will not be verified. The only requirement is to have an XML element legitimately signed by the IdP, a condition that is easily met using the IdP's public metadata. An attacker could create an arbitrary SAML response that would be accepted by SPs using vulnerable SDKs, allowing him to impersonate any Spid and/or CIE user. This vulnerability has been addressed in version 3.4.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.83.0, when JWT authentication is enabled (enable_jwt_auth: true), the OIDC userinfo cache uses token[:20] as the cache key. JWT headers produced by the same signing algorithm generate identical first 20 characters. This configuration option is not enabled by default. Most instances are not affected. An unauthenticated attacker can craft a token whose first 20 characters match a legitimate user's cached token. On cache hit, the attacker inherits the legitimate user's identity and permissions. This affects deployments with JWT/OIDC authentication enabled. Fixed in v1.83.0.

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, an unauthenticated attacker can overwrite the entire infrastructure configuration of a self-hosted Hoppscotch instance including OAuth provider credentials and SMTP settings by sending a single HTTP POST request with no authentication. The endpoint POST /v1/onboarding/config has no authentication guard and performs no check on whether onboarding was already completed. A successful exploit allows the attacker to replace the instance's Google/GitHub/Microsoft OAuth application credentials with their own, causing all subsequent user logins via SSO to authenticate against the attacker's OAuth app. The attacker captures OAuth tokens and email addresses of every user who logs in after the exploit. Additionally, the endpoint returns a recovery token that can be used to read all stored secrets in plaintext, including SMTP passwords and any other configured credentials. Version 2026.2.0 fixes the issue.

Sentry is a developer-first error tracking and performance monitoring tool. Versions 21.12.0 through 26.1.0 have a critical vulnerability in its SAML SSO implementation which allows an attacker to take over any user account by using a malicious SAML Identity Provider and another organization on the same Sentry instance. Self-hosted users are only at risk if the following criteria is met: ore than one organizations are configured (SENTRY_SINGLE_ORGANIZATION = True), or malicious user has existing access and permissions to modify SSO settings for another organization in a multo-organization instance. This issue has been fixed in version 26.2.0. To workaround this issue, implement user account-based two-factor authentication to prevent an attacker from being able to complete authentication with a victim's user account. Organization administrators cannot do this on a user's behalf, this requires individual users to ensure 2FA has been enabled for their account.
