How to Fix CVE-2026-119977 in Wordpress

The two-minute check

1. Log into your WordPress dashboard and look at the bottom of any admin screen. It shows the installed version number.
2. Compare that number to the range the record names: versions 4.7 through 7.1.3 (NVD).
3. If a web developer or agency manages your site, ask them which version is currently running.

When you can stop reading

The record lists only wordpress and WordPress Core as affected. If you don't run a WordPress website on a server you control, this bug does not apply to you. You can close this tab.

What the official record says

This flaw carries a Common Vulnerability Scoring System (CVSS) score of 8.1, rated HIGH (NVD). The scoring detail shows the attack comes over the network, needs no password, and needs no click from anyone (NVD). It also shows the attack complexity is high, meaning the attacker needs specific conditions to line up, namely the site being mid-upgrade.

The Exploit Prediction Scoring System (EPSS) puts the probability of exploitation in the next 30 days at 1.0%, in the 63.5th percentile of all scored flaws (FIRST.org). That is a low chance of exploitation in the next 30 days. EPSS is a forecast of near-term attacker activity, not a measure of how damaging the flaw is if it does get used.

This flaw is on the Cybersecurity and Infrastructure Security Agency (CISA) Known Exploited Vulnerabilities (KEV) catalog, added November 3, 2026 (CISA KEV). Being on that list means criminals are already using this flaw against real websites. A vendor patch is available, covered below.

What that means for a business like yours

No password and no click needed means your website's normal defenses, like staff training or login screens, do not block this. The high attack complexity narrows the window to moments when the site is actively upgrading. That window still exists every time WordPress Core updates itself, so it is worth closing properly rather than ignoring.

If someone else manages your IT

Send this to your web developer, host, or IT provider. Keep it short and specific.

• "Please confirm our WordPress Core version."
• "Please update it to 7.1.4 or later, per the official release notes."
• "Please confirm the update is complete and tell me the new version number."

If you manage it yourself

1. Back up your website files and database before making any changes.
2. Log into your WordPress admin dashboard.
3. Go to the Updates screen, usually found under Dashboard in the left menu.
4. If a core update is offered, click "Update Now."
5. If no update shows, download WordPress 7.1.4 directly from the official release page and follow the install instructions there.
6. Once finished, confirm the version number shown in your dashboard footer reads 7.1.4 or later.

If your website handles sensitive data, it may also be worth reviewing who has admin access through privileged access management.

This flaw is on the CISA Known Exploited Vulnerabilities catalog, with a federal remediation due date of November 6, 2026 (CISA KEV catalog). That due date applies to federal agencies, but it is a useful signal for everyone. The honest answer for your business is: now.

Log back into your WordPress dashboard after updating. Check the version number shown at the bottom of any admin screen. It should read 7.1.4 or later, matching the version named in the official release notes. Do not rely on an update progress bar alone; confirm the number directly.

If you cannot update immediately, a few steps reduce exposure without removing it. None of these replace the patch.

• Avoid starting manual core upgrades until you can complete them in one sitting. This limits how often the vulnerable upgrade window opens.
• Restrict who has admin access to your WordPress dashboard. Fewer accounts that can trigger upgrades means fewer chances for the window to open unexpectedly.
• Ask your host or IT provider to watch server logs for unusual activity during any upgrade attempt. This won't stop an attack but can help you catch one early.

These are stopgaps, not fixes. Plan to apply the real update as soon as you reasonably can.

Do I have to do anything if I only use WordPress for a personal blog?

The record does not distinguish between personal and business sites. If the software is WordPress Core in the affected version range, the same check and update apply regardless of how you use the site.

Will updating WordPress break anything on my site?

The record doesn't say which plugins or themes might be affected by the update. Back up your site first, and check your plugins still work normally after updating.

Does this affect our hosting provider's servers directly, or just my website?

The record names WordPress Core as the affected product, not the underlying server operating system. The vulnerable code runs inside WordPress itself, during its own upgrade process.

How do I know if an attacker already used this against my site?

The record doesn't provide a way to detect past exploitation. If you're concerned, a free IT assessment can help review your site's current state.
