Threat actors are exploiting the newly disclosed PaperCut flaws to facilitate credential theft in attacks targeting the education sector in the U.S. and Europe. The Arctic Wolf Adversary Research Team said it observed attackers exploiting CVE-2026-81578 and CVE-2026-82078 – an authentication bypass and remote code execution chain – to conduct command execution and reconnaissance, as well as create privileged accounts. "Observed post-exploitation activity included delivery of Windows registry hive collection tools, Metasploit/Meterpreter-related Java payloads, and commands used to identify hosts, users, processes, and sensitive configuration data," Arctic Wolf said. The cybersecurity company told The Hacker News that the activity has targeted vulnerable PaperCut servers across the education sector, impacting organizations ranging from K-12 schools to major universities in the U.S. and Europe. Some of the identified malicious activity includes - Running discover...

PostgreSQL has released updates to address a security flaw that allows an account with the REPLICATION attribute to run arbitrary code as the operating-system user running the database server. The flaw, tracked as CVE-2026-6471 (CVSS score: 7.2), has been present since logical decoding was introduced in PostgreSQL 9.4 in 2014. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected. Exploitation requires an account carrying the REPLICATION attribute and a server running with wal_level = logical. Backup tools, standby servers, change data capture (CDC) pipelines, and monitoring systems routinely hold that attribute. The fix, shipped on August 13, adds a server parameter called output_plugin_libraries that lists which libraries may be loaded as logical decoding output plugins, defaulting to 'pgoutput, test_decoding'. Installations using any other output plugin, wal2json, and decoderbufs among them, will have logical decoding refused aft...

Threat actors are exploiting two critical security flaws in WordPress plugins Super Forms and Elementor Pro, according to findings from Wordfence. The vulnerabilities in question are - CVE-2026-14894 (CVSS score: 9.8) - A missing file type validation vulnerability in Super Forms – Drag & Drop Form Builder that allows unauthenticated attackers to upload files of any type, including executable PHP files, leading to remote code execution. (Fixed in version 6.3.314) CVE-2026-32475 (CVSS score: 9.0/9.8) - A vulnerability in Elementor Pro that allows unauthenticated attackers to upload files of any type, including executable PHP files, leading to remote code execution. (Fixed in version 4.2.2) As with arbitrary file upload vulnerabilities of this kind, an attacker can leverage them to write a PHP web shell to the site and execute arbitrary code, which can then be abused to create administrator accounts, exfiltrate data, or seize control of the entire WordPress site. It...

Plex is urging users to update their instances to the latest version following the release of an update that patches multiple security flaws. The fixes are available in Plex Media Server 1.43.3 and Plex Desktop 1.115.0. The streaming media service did not elaborate on what those issues are, but said CVE identifiers have been requested for them. "We recommend all server owners and Desktop users update to the latest version as soon as possible," Plex said in an announcement this week. "If you're running Plex Media Server on a NAS device, the updated version may not be available in their package manager yet, but you can install the package manually." In August 2025, Plex addressed a high-severity security flaw ( CVE-2025-34158 , CVSS score: 8.5), an authentication bug that stemmed from the "/myplex/account" endpoint incorrectly exposing the server owner's account details, including their administrative access token, even when accessed by any...

Google on Thursday released security updates to patch 12 vulnerabilities, including one that has come under active exploitation in the wild. The high-severity vulnerability, tracked as CVE-2026-85046 (CVSS score: 8.8), has been described as a type confusion bug in V8, Chrome's JavaScript and WebAssembly engine. "Type confusion in V8 in Google Chrome prior to 152.0.7977.82 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page," reads a description of the flaw in CVE.org. Security researcher Salvatore Gulizia (aka Serotav) has been credited with discovering and reporting the flaw on August 4, 2026. The researcher has been awarded a bug bounty of $1,000 for responsible disclosure. In a separate blog post detailing the issue, Gulizia  described it as a "V8 bug in the compilers that leads to an array containing PACKED_ELEMENTS to receive the map PACKED_SMI_ELEMENTS, this can be turned into arbitrary read/write on the J...
