Mattermost versions 9.5.x <= 9.5.9 fail to properly filter the channel data when ElasticSearch is enabled which allows a user to get private channel names by using cmd+K/ctrl+K.

Mattermost versions 9.10.x <= 9.10.2, 9.11.x <= 9.11.1, 9.5.x <= 9.5.9 fail to check that the origin of the message in an integration action matches with the original post metadata which allows an authenticated user to delete an arbitrary post.

Apache NiFi 1.10.0 through 1.27.0 and 2.0.0-M1 through 2.0.0-M3 support a description field for Parameters in a Parameter Context configuration that is vulnerable to cross-site scripting. An authenticated user, authorized to configure a Parameter Context, can enter arbitrary JavaScript code, which the client browser will execute within the session context of the authenticated user. Upgrading to Apache NiFi 1.28.0 or 2.0.0-M4 is the recommended mitigation.

Sophos CEO Joe Levy says the $859 million deal to acquire SecureWorks from majority owner Dell Technologies will put the Taegis platform — with network detection and response, vulnerability detection and response, and identity threat detection and response capabilities — at the core.

Windows 11 machines remain open to downgrade attacks, where attackers can abuse the Windows Update process to revive a patched driver signature enforcement (DSE) bypass.

The nation leads in the number of capture-the-flag tournaments sponsored by government and industry — a strategy from which Western nations could learn.

LLMs tend to miss the forest for the trees, understanding specific instructions but not their broader context. Bad actors can take advantage of this myopia to get them to do malicious things, with a new prompt-injection technique.

### Impact IdentityServer's local API authentication handler performs insufficient validation of the `cnf` claim in DPoP access tokens. This allows an attacker to use leaked DPoP access tokens at local api endpoints even without possessing the private key for signing proof tokens. Note that this only impacts custom endpoints within an IdentityServer implementation that have explicitly used the `LocalApiAuthenticationHandler` for authentication. It does not impact: - OAuth or OIDC protocol endpoints defined by IdentityServer, such as the authorize and token endpoints. - Typical UI pages within an IdentityServer implementation, which are not normally authorized with the local API authentication handler. - The use of DPoP to create sender-constrained tokens in IdentityServer that are consumed by external API resources. - The use of DPoP to sender-constrain refresh tokens issued to public clients. ## Are you affected? This vulnerability only affects IdentityServer implementations that a...

### Summary An issue on Coder's login page allows attackers to craft a Coder URL that when clicked by a logged in user could redirect them to a website the attacker controls, e.g. https://google.com. ### Details On the login page, Coder checks for the presence of a `redirect` query parameter. On successful login, the user would be redirected to the location of the parameter. Improper sanitization allows attackers to specify a URL outside of the Coder application to redirect users to. ### Impact Coder users could potentially be redirected to a untrusted website if tricked into clicking a URL crafted by the attacker. Coder authentication tokens are **not** leaked to the resulting website. To check if your deployment is vulnerable, visit the following URL for your Coder deployment: - `https://<coder url>/login?redirect=https%3A%2F%2Fcoder.com%2Fdocs` ### Patched Versions This vulnerability is remedied in - v2.16.1 - v2.15.3 - v2.14.4 All versions prior to 2.3.1 are not affected. ###...
