Emergency Response to PHP RCE in the Wild

Out of an abundance of caution we are selectively shutting down all of our public web sites in response to a severe PHP RCE that was going to be disclosed tomorrow morning.  Unfortunately, it looks like there are already functional proof-of-concept exploits for the two problems in the wild.  This includes webmail, forums, membertools, sonic.com, as well as ancillary other services, including sonicstatus.com.  We will work on restoring all of these services as quickly as possible once this fixes become available tomorrow or we are confident that we’re able to use local mitigations to close the exploit paths.

Update Wed Oct 21 09:46:46 PDT 2026: PHP released their fixed versions this morning and we’ve been working on rolling out the updates as quickly as possible to restore all affected services. We expect that all disabled systems except for members.sonic.net to be back online in the next hour. -Kelsey

Update Wed Oct 21 10:42:42 PDT 2026: All disabled systems except for members.sonic.net are back online, members.sonic.net relies on a version of php which has not been patched yet.  -Kelsey

Update Wed Oct 21 12:15:02 PDT 2026: All disabled systems except for members.sonic.net are back online for real this time, webmail had been fixed but the static maintenance page was accidentally left in place.  -Kelsey

Update Wed Oct 21 18:12:02 PDT 2026:  members.sonic.net has been returned to service and all remediation work for external resources has been completed.  -Kelsey, and the rest of the Systems and Programming.

  1. What is PCP?
    What is RCE?
    Please don’t use initials such as these when communicating with the general public, who may not be familiar with industry-specific terminology.

  2. PHP is a free, open-source, server-side scripting language designed primarily for web development. Originally created by Rasmus Lerdorf in 1993, it has grown to become the foundational backbone of the modern internet, powering nearly 70% of all websites with a known server-side language.

    An RCE (Remote Code Execution) is a critical security vulnerability or attack that allows an unauthorized threat actor to run malicious code or commands on a target system, server, or network from a remote location without physical access.

  3. I’m still getting the same emergency maintenance message when I try to log in to webmail.

  4. Kathleen, sorry to hear that. If you’re on a computer, hold down the shift key while you click the refresh button on your browser. This should clear the issue up.

  5. Like Kathleen Johnson, I still can’t access my webmail, but I opened my Apple mail and it seems to be able to download my web mail as a work-around. I hope this is helpful for others.

  6. Mine is still showing the “Emergency Maintenance
    webmail.sonic.net has been taken offline for emergency maintenance and will be returned to service as soon as possible.
    Please see our MOTD entry for more details.”
    message.

  7. Hi. I am trying to access email on Safari on my iPhone but I still can’t access it. I still receive the emergency maintenance message. Is there a fix for this? Thanks in advance

  8. Steve, I think it’s probably a caching problem on the iPhone, I’m not positive how to force a cache clear and reload on one.

  9. \IT’S 6:07 AND MY EMAIL IS STILL NOT UP. I HAVE RESTARTED MY COMPUTER SEVERAL TIMES. PLEASE ADVISE

  10. Susan, if you’re still having trouble I would suggest reaching out to support.

  11. I was also still getting the “emergency maintenance” message this evening, but looked here and noticed Mike’s suggestion to Kethleen this morn to hold down the shift key while you click the refresh button on your browser. That worked right away. Thanks, Mike!
