A flaw was found in Keycloak. An active keycloak session can be hijacked by initiating a new authentication (having the query parameter prompt=login) and forcing the user to enter his credentials once again. If the user cancels this re-authentication by clicking Restart login, the account takeover could take place as the new session, with a different SUB, will have the same SID as the previous session.

A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field. #### Acknowledgements: Special thanks to Axel Flamcourt for reporting this issue and helping us improve our project.

A potential security flaw in the "checkLoginIframe" which allows unvalidated cross-origin messages, enabling potential DDoS attacks. By exploiting this vulnerability, attackers could coordinate to send millions of requests in seconds using simple code, significantly impacting the application's availability without proper origin validation for incoming messages. #### Acknowledgements Special thanks to Adriano Márcio Monteiro from BRZTEC for reporting this issue and helping us improve our project.

A flaw was found in keycloak 22.0.5. Errors in browser client during setup/auth with "Security Key login" (WebAuthn) are written into the form, send to Keycloak and logged without escaping allowing log injection.

# Microsoft Security Advisory CVE-2024-21409 | .NET Elevation of Privilege Vulnerability ## <a name="executive-summary"></a>Executive summary Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 6.0, .NET 7.0 ,and .NET 8.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A use-after-free vulnerability exists in WPF which may result in Elevation of Privilege when viewing untrusted documents. This is a Windows only vulnerability. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/303 ## <a name="mitigation-factors"></a>Mitigation factors This vulnerability affects only WPF-based applications. ## <a name="affected-software"></a>Affected software * Any .NET 7.0 application running on .NET 6.0.28 or earlier. * Any .NET 7.0 application running on .NET 7.0.17 or earlier. * Any .NET 8.0 application running on .N...

Using particular inputs with `@solana/web3.js` will result in memory exhaustion (OOM). If you have a server, client, mobile, or desktop product that accepts untrusted input for use with `@solana/web3.js`, your application/service may crash, resulting in a loss of availability.

### Impact Failing webhooks logs are available when solution is not in debug mode. Those logs can contain information that is critical. ### Affected Versions Umbraco versions 13.0.0 - 13.1.1 ### Patches 13.1.1 ### Workarounds Disabling webhooks functionality.

## Impact _What kind of vulnerability is it? Who is impacted?_ An attacker can use this bug to bypass the block gas limit and gas payment completely to perform a full Denial-of-Service against the chain. ## Disclosure Evmos versions below `v11.0.1` do not check for `MsgEthereumTx` messages that are nested under other messages. This allows a malicious actor to perform EVM transactions that do not meet the checks performed under `newEthAnteHandler`. This opens the possibility for the DOS of validators and consequently halt the chain through an infinite EVM execution. ### Additional details The attack scenario is as follows: 1. The attacker deploys a simple smart contract with an infinite loop to the chain. 2. The attacker calls the smart contract using an embedded transaction with an extremely high gas value (`uint64` max or similar). 3. Once the transaction is included in a block, nodes will try to execute the EVM transaction with almost infinite gas and get stuck. **This stops...

Due to a permissive regular expression hardcoded for filtering allowed hosts to register a dynamic client, a malicious user with enough information about the environment could benefit and jeopardize an environment with this specific Dynamic Client Registration with TrustedDomain configuration previously unauthorized. #### Acknowledgements: Special thanks to Bastian Kanbach for reporting this issue and helping us improve our security.

Keycloak allows arbitrary URLs as SAML Assertion Consumer Service POST Binding URL (ACS), including JavaScript URIs (javascript:). Allowing JavaScript URIs in combination with HTML forms leads to JavaScript evaluation in the context of the embedding origin on form submission. #### Acknowledgements: Special thanks to Lauritz Holtmann for reporting this issue and helping us improve our project.
