### Summary A vulnerability in Zitadel's token verification prematurely marked sessions as authenticated when only one factor was verified. ### Impact Zitadel provides an API for managing sessions, enabling custom login experiences in a dedicated UI or direct integration into applications. Session Tokens are issued for active sessions, which can be used as Bearer tokens to call the Zitadel API. Starting from 2.55.0 (see other affected versions below), Zitadel only required multi factor authentication in case the login policy has either enabled `requireMFA` or `requireMFAForLocalUsers`. If a user has set up MFA without this requirement, Zitadel would consider single factor auhtenticated sessions as valid as well and not require multiple factors. Bypassing second authentication factors weakens multifactor authentication and enables attackers to bypass the more secure factor. An attacker can target the TOTP code alone, only six digits, bypassing password verification entirely and po...

### Summary A vulnerability in Zitadel allowed brute-force attack on OTP, TOTP and password allowing to impersonate the attacked user. ### Impact An attacker can perform an online brute-force attack on OTP, TOTP, and passwords. While Zitadel allows preventing online brute force attacks in scenarios like TOTP, Email OTP, or passwords using a lockout mechanism. The mechanism is not enabled by default and can cause a denial of service for the corresponding user if enabled. Additionally, the mitigation strategies were not fully implemented in the more recent resource-based APIs. ### Affected Versions All versions within the following ranges, including release candidates (RCs), are affected: - **4.x**: `4.0.0` to `4.4.0` (including RC versions) - **3.x**: `3.0.0` to `3.4.2` (including RC versions) - **2.x**: `v2.0.0` to `2.71.17` ### Patches The vulnerability has been addressed in the latest releases. The patch resolves the issue by enforcing the lockout policy on all OTP, TOTP and p...

### Impact A potential vulnerability exists in ZITADEL's password reset mechanism. ZITADEL utilizes the Forwarded or X-Forwarded-Host header from incoming requests to construct the URL for the password reset confirmation link. This link, containing a secret code, is then emailed to the user. If an attacker can manipulate these headers (e.g., via host header injection), they could cause ZITADEL to generate a password reset link pointing to a malicious domain controlled by the attacker. If the user clicks this manipulated link in the email, the secret reset code embedded in the URL can be captured by the attacker. This captured code could then be used to reset the user's password and gain unauthorized access to their account. It's important to note that this specific attack vector is mitigated for accounts that have Multi-Factor Authentication (MFA) or Passwordless authentication enabled. ### Affected Versions Systems running one of the following versions: - **4.x**: `4.0.0` to `4.5...

# Patch This is fixed with [commit b953092](https://github.com/PixarAnimationStudios/OpenUSD/commit/b9530922b6a8ea72cd43661226b693fff8abbe4c), with the fix available in OpenUSD 25.11 and onwards. # Summary We have been advised by Zero Day Initiative that our usage of the USD framework may constitute a Use-After-Free Remote Code Execution Vulnerability. They have sent us the attached file illustrating the issue. Indeed, we see a use after free exception when running the file through our importer with an address sanitizer. [zdi-23709-poc0.zip](https://github.com/user-attachments/files/17474297/zdi-23709-poc0.zip) Thanks in advance.

### Impact Session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim's browser or steal the victim's currently valid session. Session identifiers are now regenerated after each login. ### Patches This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4 ### References [https://en.wikipedia.org/wiki/Session_fixation](https://en.wikipedia.org/wiki/Session_fixation)

### Summary The default HTML editor provider allows unauthenticated file uploads and images can overwrite existing files. ### Description An unauthenticated user can upload and replace existing files allowing defacing a website and combined with other issue, injection XSS payloads.

### Summary The out-of-box experience for HTML editing allows unauthenticated users to upload files. This opens a potential vector to other security issues and is not needed on most implementations. ### Details The new out-of-box experience blocks that endpoint to unauthenticated users. If there is a real need for the implementation to allow unauthenticated uploads, then the web.config can be edited by the implementer to remove that block and open the endpoint to the public.
