### Summary It's possible for an attacker to construct an XLSX file which links media from external URLs. When opening the XLSX file, PhpSpreadsheet retrieves the image size and type by reading the file contents, if the provided path is a URL. By using specially crafted `php://filter` URLs an attacker can leak the contents of any file or URL. Note that this vulnerability is different from [GHSA-w9xv-qf98-ccq4](https://github.com/PHPOffice/PhpSpreadsheet/security/advisories/GHSA-w9xv-qf98-ccq4), and resides in a different component. ### Details When an XLSX file is opened, the XLSX reader calls `setPath()` with the path provided in the `xl/drawings/_rels/drawing1.xml.rels` file in the XLSX archive: ```php if (isset($images[$embedImageKey])) { // ...omit irrelevant code... } else { $linkImageKey = (string) self::getArrayItem( $blip->attributes('http://schemas.openxmlformats.org/officeDocument/2006/relationships'), 'link' ); if (isset($images[$linkImag...

Get the scoop before it's too late! ⚡ Threat of the Week Double Trouble: Evil Corp & LockBit Fall: A consortium of international law enforcement agencies took steps to arrest four

Internet infrastructure provider Cloudflare fends off a massive 3.8 Tbps DDoS attack, surpassing the previous record. Learn how…

Continuous Threat Exposure Management (CTEM) is a strategic framework that helps organizations continuously assess and manage cyber risk. It breaks down the complex task of managing security threats into five distinct stages: Scoping, Discovery, Prioritization, Validation, and Mobilization. Each of these stages plays a crucial role in identifying, addressing, and mitigating vulnerabilities -

NIST standardized three algorithms for post-quantum cryptography. What does that mean for the information and communications technology (ICT) industry?

Organizations that get relieved of credentials to their cloud environments can quickly find themselves part of a disturbing new trend: Cybercriminals using stolen cloud credentials to operate and resell sexualized AI-powered chat services. Researchers say these illicit chat bots, which use custom jailbreaks to bypass content filtering, often veer into darker role-playing scenarios, including child sexual exploitation and rape.

Amid the noise of new solutions and buzzwords, understanding the balance between securing infrastructure and implementing runtime security is key to crafting an effective cloud strategy.

Cybersecurity researchers have uncovered a new cryptojacking campaign targeting the Docker Engine API with the goal of co-opting the instances to join a malicious Docker Swarm controlled by the threat actor. This enabled the attackers to "use Docker Swarm's orchestration features for command-and-control (C2) purposes," Datadog researchers Matt Muir and Andy Giron said in an analysis. The attacks

Hold onto your hats, folks, because the cybersecurity world is anything but quiet! Last week, we dodged a bullet when we discovered vulnerabilities in CUPS that could've opened the door to remote attacks. Google's switch to Rust is paying off big time, slashing memory-related vulnerabilities in Android. But it wasn't all good news – Kaspersky's forced exit from the US market left users with more
