#vulnerability

### Summary The `env` and `expandenv` template functions which is enabled by default in [Sprig](https://masterminds.github.io/sprig/) enables capturing of env variables on host. While this may not be a problem on single-user (super admin) installations, on multi-user installations, this allows non-super-admin users with campaign or template permissions to use the `{{ env }}` template expression to capture sensitive environment variables. **Upgrade to [v5.0.2](https://github.com/knadh/listmonk/releases/tag/v5.0.2)** to mitigate. --------- # Demonstration ### Description A critical template injection vulnerability exists in Listmonk's campaign preview functionality that allows authenticated users with minimal privileges (campaigns:get & campaigns:get_all) to extract sensitive system data, including database credentials, SMTP passwords, and admin credentials due to some dangerous function being allowed. ### Proof of Concept - Create a user and give him `campaigns:get` and `campaigns...

A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster

The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.

Open source has always been paradoxical: it's software developed by passionate developers and given away for free, yet it's monetized and funded by some of the largest companies in the world. An underdog, once called "a cancer," and yet it's the single largest driver of innovation and technological progress we have ever seen. In the world of open source, paradox will always exist, but nowhere more so than in the understanding of security vulnerabilities.Twenty-five years ago, the Common Vulnerabilities and Exposures (CVE) program was established to standardize the naming and tracking of softw

Red Hat is built on open source, a global decentralized and transparent community of international engineers who put security at the forefront of technology. Red Hat Enterprise Linux (RHEL) is the trusted operating system (OS) used by more than 90% of Fortune 500 companies and customers in more than 174 countries. This trust is earned largely due to RHEL's reliability and stability as well as Red Hat's long history of actively contributing to open source projects. There is one key factor that is often discounted with respect to the Linux OS, however, which is its reputation for having enhanced

### Overview A flaw in Jackson-core's `JsonLocation._appendSourceDesc` method allows up to 500 bytes of unintended memory content to be included in exception messages. When parsing JSON from a byte array with an offset and length, the exception message incorrectly reads from the beginning of the array instead of the logical payload start. This results in possible **information disclosure** in systems using **pooled or reused buffers**, like Netty or Vert.x. ### Details The vulnerability affects the creation of exception messages like: ``` JsonParseException: Unexpected character ... at [Source: (byte[])...] ``` When `JsonFactory.createParser(byte[] data, int offset, int len)` is used, and an error occurs while parsing, the exception message should include a snippet from the specified logical payload. However, the method `_appendSourceDesc` ignores the `offset`, and always starts reading from index `0`. If the buffer contains residual sensitive data from a previous request, such a...

### Summary A **Denial of Service (DoS)** vulnerability was discovered in the CoreDNS DNS-over-QUIC (DoQ) server implementation. The server previously created a new goroutine for every incoming QUIC stream without imposing any limits on the number of concurrent streams or goroutines. A remote, unauthenticated attacker could open a large number of streams, leading to uncontrolled memory consumption and eventually causing an Out Of Memory (OOM) crash — especially in containerized or memory-constrained environments. ### Impact - **Component**: `server_quic.go` - **Attack Vector**: Remote, network-based - **Attack Complexity**: Low - **Privileges Required**: None - **User Interaction**: None - **Impact**: High availability loss (OOM kill or unresponsiveness) This issue affects deployments with `quic://` enabled in the Corefile. A single attacker can cause the CoreDNS instance to become unresponsive using minimal bandwidth and CPU. ### Patches The patch introduces two key mitigation m...
