Critical wp2shell WordPress flaws exploited to install webshells
Hackers are exploiting the “wp2shell” critical vulnerability suite (CVE-2026-63030 and CVE-2026-60137) affecting WordPress Core to deploy persistent webshells and install malicious plugins on affected servers. The critical exploit chain abuses the WordPress REST API’s batch-processing feature, allowing remote attackers to execute code on vulnerable installations without the need to authenticate. Although the technical details were not released, […]
WordPress Core “wp2shell” RCE flaws get public exploits, patch now
Public exploits have been released for the critical “wp2shell” remote code execution vulnerabilities affecting WordPress Core, making it imperative that administrators patch their sites immediately. The wp2shell attack consists of two flaws, tracked as CVE-2026-63030 and CVE-2026-60137, that can be chained together to achieve pre-authentication remote code execution against WordPress installs running versions 6.9.x and […]
Critical UniFi OS bug lets hackers gain root without authentication
Attackers can chain three already fixed vulnerabilities in the Ubiquiti UniFi OS server to execute remote code with root privileges and without authentication. The security issues are tracked as CVE-2026-34908, CVE-2026-34909, and CVE-2026-34910. They have been addressed in May and impact UniFi OS Server versions 5.0.6 and earlier. While all three flaws received the maximum severity […]

During the second day of Pwn2Own Berlin 2026, competitors collected $385,750 in cash awards after exploiting 15 unique zero-day vulnerabilities in multiple products, including Windows 11, Microsoft Exchange, and Red Hat Enterprise Linux for Workstations. The Pwn2Own Berlin 2026 hacking competition takes place at the OffensiveCon conference from May 14 to May 16 and focuses on enterprise technologies and […]
New Linux ‘Dirty Frag’ zero-day gives root on all major distros
A new Linux zero-day exploit, named Dirty Frag, allows local attackers to gain root privileges on most major Linux distributions with a single command. Security researcher Hyunwoo Kim, who disclosed it earlier today and published a proof-of-concept (PoC) exploit, says this local privilege escalation was introduced roughly nine years ago in the Linux kernel’s algif_aead cryptographic algorithm interface. Dirty […]
New Progress ShareFile flaws can be chained in pre-auth RCE attacks
Two vulnerabilities in Progress ShareFile, an enterprise-grade secure file transfer solution, can be chained to enable unauthenticated file exfiltration from affected environments. Progress ShareFile is a document sharing and collaboration product typically used by large and mid-sized companies. Such solutions are an attractive target for ransomware actors, as previously seen in Clop data-theft attacks exploiting bugs in Accellion […]
Coruna iOS exploit framework linked to Triangulation attacks
The Coruna exploit kit is an evolution of the framework used in the Operation Triangulation espionage campaign, which in 2023 targeted iPhones via zero-click iMessage exploits. The software has been expanded to target modern hardware, specifically including Apple’s A17 and M3 chips, as well as operating systems up to iOS 17.2. Coruna contains five full iOS […]
CISA orders feds to patch DarkSword iOS flaws exploited attacks
CISA ordered U.S. government agencies to patch three iOS vulnerabilities targeted in cryptocurrency theft and cyberespionage attacks using the DarkSword exploit kit. As Google Threat Intelligence Group (GTIG) and iVerify researchers revealed last week, the DarkSword delivery framework abuses a chain of six vulnerabilities tracked as CVE-2025-31277, CVE-2025-43529, CVE-2026-20700, CVE-2025-14174, CVE-2025-43510, and CVE-2025-43520. These flaws enable […]
New DarkSword iOS exploit used in infostealer attack on iPhones
A new exploit kit for iOS devices and delivery framework dubbed “DarkSword” has been used to steal a wide range of personal information, including data from cryptocurrency wallet apps. DarkSword targets iPhones running iOS 18.4 through 18.7 and is linked to multiple actors, including UNC6353, suspected to be Russian, who used the Coruna exploit chain disclosed earlier this month. […]
Apple patches older iPhones and iPads against Coruna exploits
Apple has released security updates to patch older iPhones and iPads against a set of vulnerabilities targeted in cyberespionage and crypto-theft attacks using the Coruna exploit kit. Some of these security flaws have already been addressed in earlier updates for newer iOS device models, starting in September 2023. “This fix associated with the Coruna exploit,” Apple […]
