A business logic vulnerability in Easy Appointments v1.5.1 allows attackers to cause a Denial of Service (DoS) via unspecified vectors.

Europol has announced the takedown of distributed denial of service (DDoS)-for-hire services that were used to launch thousands of cyber-attacks across the world. In connection with the operation, Polish authorities have arrested four individuals and the United States has seized nine domains that are associated with the now-defunct platforms. "The suspects are believed to be behind six separate

Polish authorities arrest 4 behind major DDoS-for-hire sites used in global attacks. Europol, US, Germany, and Dutch forces…

Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ. During unmarshalling of OpenWire commands the size value of buffers was not properly validated which could lead to excessive memory allocation and be exploited to cause a denial of service (DoS) by depleting process memory, thereby affecting applications and services that rely on the availability of the ActiveMQ broker when not using mutual TLS connections. This issue affects Apache ActiveMQ: from 6.0.0 before 6.1.6, from 5.18.0 before 5.18.7, from 5.17.0 before 5.17.7, before 5.16.8. ActiveMQ 5.19.0 is not affected. Users are recommended to upgrade to version 6.1.6+, 5.19.0+, 5.18.7+, 5.17.7, or 5.16.8 or which fixes the issue. Existing users may implement mutual TLS to mitigate the risk on affected brokers.

Threat actors have been observed actively exploiting security flaws in GeoVision end-of-life (EoL) Internet of Things (IoT) devices to corral them into a Mirai botnet for conducting distributed denial-of-service (DDoS) attacks. The activity, first observed by the Akamai Security Intelligence and Response Team (SIRT) in early April 2025, involves the exploitation of two operating system command

**Vulnerable MobSF Versions:** <= v4.3.2 **Details:** MobSF is a widely adopted mobile application security testing tool used by security teams across numerous organizations. Typically, MobSF is deployed on centralized internal or cloud-based servers that also host other security tools and web applications. Access to the MobSF web interface is often granted to internal security teams, audit teams, and external vendors. MobSF provides a feature that allows users to upload ZIP files for static analysis. Upon upload, these ZIP files are automatically extracted and stored within the MobSF directory. However, this functionality lacks a check on the total uncompressed size of the ZIP file, making it vulnerable to a ZIP of Death (zip bomb) attack. Due to the absence of safeguards against oversized extractions, an attacker can craft a specially prepared ZIP file that is small in compressed form but expands to a massive size upon extraction. Exploiting this, an attacker can exhaust the serv...

An XML External Entity (XXE) vulnerability exists in the gateway component of WSO2 API Manager due to insufficient validation of XML input in crafted URL paths. User-supplied XML is parsed without appropriate restrictions, enabling external entity resolution. This vulnerability can be exploited by an unauthenticated remote attacker to read files from the server’s filesystem or perform denial-of-service (DoS) attacks. * On systems running JDK 7 or early JDK 8, full file contents may be exposed. * On later versions of JDK 8 and newer, only the first line of a file may be read, due to improvements in XML parser behavior. * DoS attacks such as "Billion Laughs" payloads can cause service disruption.

### Impact When run as a server, OPA exposes an HTTP[ Data API](https://www.openpolicyagent.org/docs/latest/rest-api/#data-api) for reading and writing documents. Requesting a virtual document through the Data API entails policy evaluation, where a Rego query containing a single data document [reference](https://www.openpolicyagent.org/docs/latest/policy-language/#references) is constructed from the requested path. This query is then used for policy evaluation. A HTTP request path can be crafted in a way that injects Rego code into the constructed query. The evaluation result cannot be made to return any other data than what is generated by the requested path, but this path can be misdirected, and the injected Rego code can be crafted to make the query succeed or fail; opening up for oracle attacks or, given the right circumstances, erroneous policy decision results. Furthermore, the injected code can be crafted to be computationally expensive, resulting in a Denial Of Service (DoS) ...
