WordPress RCE (Remote Code Execution) Update to 7.0.4!

-

 


A WordPress RCE (Remote Code Execution) vulnerability is a security flaw that allows an attacker to execute arbitrary code on the web server hosting a WordPress site. Successful exploitation can lead to full site compromise, malware installation, data theft, account creation, or complete server takeover.

Recent WordPress RCE Examples

1. WP2Shell (CVE-2026-63030 + CVE-2026-60137)

In July 2026, WordPress disclosed a critical attack chain dubbed WP2Shell. The chain combined a REST API flaw and a SQL injection vulnerability, allowing unauthenticated attackers to achieve remote code execution on affected WordPress Core installations. Active exploitation was later confirmed, and CISA added the vulnerabilities to its Known Exploited Vulnerabilities catalog.
Affected versions:
  • WordPress 6.9.0 through 6.9.4
  • WordPress 7.0.0 through 7.0.1
Fixed in:
  • WordPress 6.9.5
  • WordPress 7.0.2

2. Imagick/Ghostscript RCE (CVE-2026-65640)

In August 2026, WordPress released version 7.0.4 to address an authenticated RCE vulnerability involving Imagick and Ghostscript. Attackers with Author-level access could upload a specially crafted file disguised as an image and trigger code execution on vulnerable systems.

Common Indicators of Compromise

  • Unexpected administrator accounts
  • Unknown plugins or themes
  • Suspicious PHP files in wp-content/uploads
  • Unusual outbound network traffic
  • Website redirects or defacements
  • Webshells such as cmd.php, shell.php, or obfuscated PHP code

Recommended Mitigations

  1. Update WordPress Core immediately to the latest supported version.
  2. Update all plugins and themes.
  3. Remove unused plugins/themes.
  4. Restrict file upload permissions.
  5. Implement a Web Application Firewall (WAF).
  6. Monitor for unexpected admin accounts and plugin installations.
  7. Enable MFA for administrator accounts.
  8. Regularly scan for malware and webshells.

For a Security Team

When investigating a reported "WordPress RCE vulnerability," gather:
  • WordPress version
  • Installed plugin and theme inventory
  • Web server type (Apache/Nginx)
  • PHP version
  • Whether the vulnerability is in WordPress Core or a plugin/theme
  • Relevant CVE number
With those details, I can help determine exposure, provide IOC checks, and recommend remediation steps.

WSUS CVE-2025-59287 Mitigation

-
Image
CVE-2025-59287 is a critical Remote Code Execution (RCE) vulnerability affecting Windows Server Update Services (WSUS) . Here's a detailed breakdown of what it is, how it works, and what you should do about it: Overview Disclosed: October 2025 Patch Tuesday CVSS Score: 9.8 (Critical) Affected Systems: Windows Server 2012 through 2025 (including Server Core installations) Exploitability: Microsoft rates it as “Exploitation More Likely” Technical Details The vulnerability arises from unsafe deserialization of untrusted data in WSUS. Specifically, the GetCookie() endpoint in WSUS processes encrypted AuthorizationCookie objects without proper type validation. The deserialization occurs via .NET BinaryFormatter , which is known to be insecure when handling untrusted input. Attackers can send a crafted SOAP request to WSUS over port 8530 , containing a malicious AuthorizationCookie . The cookie is decrypted using a hardcoded AES key and then deserialized, allow...

Cloud Infrastructures are Having a Bad Week

Image
  Today’s disruptions across Microsoft Azure and Amazon Web Services (AWS) were significant, but they’re not signs of cloud computing’s demise. Instead, they underscore the risks of centralization and the importance of designing systems that can withstand provider-level failures. What happened today? • Microsoft Azure outage: Azure’s Front Door service suffered a major disruption due to a misconfiguration, impacting services like Outlook, Xbox, Microsoft 365, and even third-party platforms like Starbucks and Alaska Airlines. The Azure website states a little more than disruption. "Azure Front Door - Connectivity issues - Observing recovery Starting at approximately 16:00 UTC on 29 October 2025, customers and Microsoft services leveraging Azure Front Door (AFD) may have experienced latencies, timeouts, and errors. We have confirmed that an inadvertent configuration change was the trigger event for this issue. Affected Azure services may have included, but were not limited to: App S...

Broadcom is dismantling of VMware Cloud Service Providers (VCSPs)

-
Image
  What Broadcom Is Doing to the VCSP Program 1. Broadcom is shutting down the existing VCSP program Multiple sources confirm that Broadcom issued formal non‑renewal notices to many VMware Cloud Service Providers, ending contracts as of January 26, 2026 . Partners may finish existing commitments but cannot renew or create new long‑term contract commitments . 2. Moving to an invite‑only VCSP ecosystem Broadcom is replacing the open VCSP model with a highly selective, invite‑only program , keeping only a small fraction of providers . For example: • Only 19 providers in the U.S. were retained out of thousands. • Hundreds of European providers are being cut loose. 3. White Label program sunset (critical for smaller providers) The White Label model—previously the path for smaller CSPs—has been terminated (or will be phased out depending on region). This effectively eliminates market access for many small providers. 4. Providers that are cut must hand off customers Broadcom directs ...

FBI Seizes RAMP Cybercrime Forum

-
Image
The FBI has taken down RAMP (Russian Anonymous Marketplace) , one of the most active cybercrime forums used by ransomware gangs, initial access brokers, malware sellers, and extortion groups . The takedown affected both the clearnet and dark‑web (Tor) domains, which now display official FBI/DOJ seizure notices. Why RAMP Was Significant RAMP was: Known as “the only place ransomware allowed.” A major hub for groups including LockBit, ALPHV/BlackCat, Conti, DragonForce, Qilin, RansomHub , and more. A high‑trust marketplace offering malware, exploits, tutorials, and escrow services . Home to 14,000+ vetted users , some paying fees for anonymity. Impact of the Seizure 1. Major Disruption to Criminal Infrastructure The takedown is seen as a meaningful blow against ransomware‑as‑a‑service communities. 2. Forced Migration to Other Forums Criminal groups are already shifting activity to alternative platforms like Rehub . These migrations are chaotic and risky for criminals due to: Loss of rep...

Instagram Data Leak Update

  Instagram Data Leak What Happened? Cybersecurity firm Malwarebytes discovered a dataset containing personal information from approximately 17.5 million Instagram accounts circulating on dark web forums. The leaked data reportedly includes: Usernames Email addresses Phone numbers Partial physical addresses In some cases, location details .  How Did It Occur? The data appears to have been scraped via Instagram’s API , likely exploiting weaknesses in rate-limiting or privacy safeguards. A threat actor using the alias “Solonik” posted the dataset on BreachForums, claiming it originated from a 2024 API leak . Meta (Instagram’s parent company) denies any breach of internal systems , stating that the surge in password reset emails was due to a bug that allowed external parties to trigger reset requests, not unauthorized access. Risks to Users Phishing & Social Engineering: Attackers can craft convincing messages using real account details. SIM-Swapping & Account Takeove...

Notepad++ update service was compromised

-
Image
  Notepad++ update service was compromised Multiple independent security investigations confirm that Notepad++’s update infrastructure was hijacked between June and December 2025 . This was a supply-chain attack originating from a compromise at the hosting‑provider level , not from Notepad++’s code. What exactly was compromised? 1. Update traffic was intercepted and redirected Attackers manipulated the update endpoint ( getDownloadUrl.php ) so that some users requesting updates were silently redirected to malicious servers serving tampered executables . 2. It was targeted , not widespread All sources emphasize that only specific users were affected, likely in an espionage‑focused campaign , not a mass malware distribution effort. 3. Hosting provider compromise, not a Notepad++ bug The attackers gained access to the shared hosting environment , losing direct access in September 2025 but maintaining stolen internal service credentials through December 2, 2025.
