Five Critical WordPress Plugin and Theme Flaws Enable Site Takeover or RCE

Five Critical WordPress Plugin and Theme Flaws Enable Site Takeover or RCE

Aug 29, 2026 Vulnerability / Web Security
Multiple critical security flaws have been disclosed in WordPress plugins and themes, including WPMU DEV Dashboard, Avada, TranslatePress, Pods, and GiveWP, that could lead to authentication bypass, account takeover, and arbitrary code execution. The vulnerabilities, according to Wordfence and Patchstack, are listed below - CVE-2026-76581 (CVSS score: 9.8) - An authentication bypass flaw in the WPMU DEV Dashboard plugin that could allow an unauthenticated attacker, on sites connected to WPMU DEV with Hub Single-Sign On (SSO) enabled and mapped to an administrator, to obtain administrator access and achieve site takeover. (Affects all versions up to, and including, 5.0.1) CVE-2026-18431 (CVSS score: 9.8) - An arbitrary file write flaw in the Avada theme for WordPress that makes it possible for an unauthenticated attacker to write attacker-controlled files to the server, which, in turn, can be exploited to create and execute arbitrary PHP files, resulting in remote code exec...
Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

Aug 28, 2026 Vulnerability / Blockchain
Cosmos Labs has warned that a critical balance-handling flaw in the shared Cosmos EVM module was exploited to drain funds from six blockchains between August 20 and August 25, 2026. The vulnerability, designated GHSA-7g4w-cg88-2cq2 , is rated Critical by Cosmos Labs and was published without a CVE identifier, a weakness classification, or a CVSS score. Affected versions are < 0.6.2 and >= 0.7.0 < 0.7.2 , and the fix shipped in v0.6.2 and v0.7.2 on August 19. Chain operators are told to upgrade to one of those releases or later, a change that is state-breaking and requires a coordinated network upgrade. Operators who cannot upgrade immediately are told to halt the chain rather than attempt a coordinated governance upgrade. In a post-mortem published August 28 , Cosmos Labs said the flaw was reported through its bug bounty program on April 25 and was assessed at the time as posing no risk to funds on live networks. "We were unable to reproduce the vulnerability ...
Attackers Chain Two PaperCut Flaws to Execute Code Without Authentication

Attackers Chain Two PaperCut Flaws to Execute Code Without Authentication

Aug 28, 2026 Vulnerability / Web Security
Malicious actors are exploiting a newly patched security flaw in PaperCut NG and MF to execute arbitrary code on susceptible instances, as the company released a fresh emergency fix with additional hardening. "This vulnerability gives an unauthenticated attacker remote control over PaperCut's trusted configuration, which could be used to execute arbitrary Java code inside the application's process," Huntress researchers John Hammond and Andrew Brandt said . Specifically, an attacker can leverage an unauthenticated request to make changes to the server configuration and ultimately achieve code execution. Huntress has explained the flaw as follows - In unpatched versions of PaperCut NG and PaperCut MF,  a specifically crafted request can refer to one page that is rendered for the response, and another page that owns the component or action being executed. PaperCut's authorization check could trust the rendered page and miss the permissions required by the...

ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

Aug 28, 2026 Vulnerability / Cyber Espionage
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical security flaw impacting ownCloud to its Known Exploited Vulnerabilities ( KEV ) catalog following reports that a Chinese-speaking threat actor weaponized the vulnerability to target a nuclear research body in the Philippines. The vulnerability, tracked as CVE-2023-49105 (CVSS score: 9.8), is a case of WebDAV API authentication bypass that could allow an attacker to access, modify or delete any file without authentication if the username of the victim is known and the victim has no signing-key configured, which is the default configuration. Disclosed by ownCloud in November 2023, the issue impacts "core" versions from 10.6.0 through 10.13.0. It was fixed in version 10.13.1. CISA's addition of the flaw to the KEV catalog comes a couple of days after Hunt.io said it identified an open directory on the host "31.58.209[.]241," which staged custom Python scripts, o...
Two Unitree G1 EDU Humanoid Robot Flaws Enable Root RCE, One Starts Over Bluetooth

Two Unitree G1 EDU Humanoid Robot Flaws Enable Root RCE, One Starts Over Bluetooth

Aug 28, 2026 Vulnerability / IoT Security
Security researcher Olivier Laflamme has disclosed two independent root remote code execution (RCE) chains affecting the Unitree G1 EDU , including a Bluetooth Low Energy (BLE) path that can reach root on the robot's Locomotion PC. The flaws are tracked as  CVE-2026-76639  and  CVE-2026-76640 , with the first involving a network-adjacent path through chat_go and bashrunner and the second beginning from BLE proximity. An exact fixed firmware release has not been verified in any accessible Unitree guidance, leaving G1 EDU owners without a confirmed release target for either vulnerability. Laflamme said Unitree patched the cloud account-to-robot ownership check in July 2026. As of the August 27 disclosure, the current cloud-assisted route requires an account bound to the target G1 or the relevant key material already in hand. Laflamme published the research on August 27, 2026, describing the two issues as separate root-RCE paths. The research timeline shows Laflamm...
