WordPress 7.1.3 is a maintenance and security release that fixes seven security problems and four software bugs. WordPress.org recommends updating immediately. The security work covers stored cross-site scripting, private-comment disclosure, second-order SQL injection, denial of service, an Author-role capability weakness, unsafe Imgur embeds, and a dynamic-hook collision issue.
Site owners should back up the database and files, install the update, clear page and object caches, and verify the public site plus administrator workflows. This is an important update, but the individual flaws have different prerequisites; not every issue lets an anonymous visitor take over a site.
Key takeaways
- WordPress 7.1.3 was released on October 6, 2026, with seven security fixes and four bug fixes.
- One stored-XSS path begins with a pending comment and can affect the Comments administration screen.
- Another flaw could expose comments attached to private or unpublished posts without authentication.
- Several issues require Contributor, Author, or administrator access, so account permissions still matter.
- Security fixes are being backported to eligible older branches, but WordPress says only the latest release is actively maintained.

What does WordPress 7.1.3 fix?
The official announcement lists seven security fixes. The following table combines that announcement with technical access details published by WPScan and Patchstack.
| Issue | Likely starting access | Practical concern |
|---|---|---|
| Stored XSS through pending comments | Unauthenticated submission; administrator or moderator interaction is relevant | Malicious content could execute on the Comments administration page |
Denial of service in WP_Http::make_absolute_url() | Contributor or higher, according to WPScan | Crafted URL-detail processing could consume resources |
| Second-order SQL injection in WXR export | Author or higher, according to WPScan | Stored data becomes dangerous during a later export operation |
| Author users could make posts sticky | Author | A role could perform an action outside its intended capability |
| Private-post comment disclosure | Unauthenticated | Comments on private or unpublished posts could be exposed |
| Imgur embed XSS | Contributor or higher, according to WPScan | Untrusted embedded content could execute script |
| Dynamic hook action-name collision | Requires crafted status/type parameters | Forgeable values could collide with an unrelated WordPress action name |
The release also contains four maintenance fixes. WordPress does not describe 7.1.3 as a feature release, so site owners should expect security and stability improvements rather than a redesigned editor or new publishing workflow.
How serious are the WordPress 7.1.3 vulnerabilities?
The pending-comment stored XSS is the highest-severity item listed by WPScan, while several other issues are rated in the medium or low range. Risk depends on how a site is configured and who has accounts.
Public sites that accept comments have a wider exposure surface than sites with commenting disabled. Multi-author publications, membership sites, and stores should also review Contributor and Author accounts because several fixes involve authenticated roles. A site with no public comments and one trusted administrator has fewer reachable paths, but that is not a reason to leave core outdated.
There is no need to invent a worst-case scenario for every bug. The sensible response is to update promptly, review user roles, and inspect unusual recent activity. If you maintain many installations, prioritize internet-facing and multi-user sites first, then complete the rest of the fleet.
For broader protection beyond this release, use our Linux server hardening checklist and keep plugins, themes, PHP, and the operating system supported.
What changed for Imgur embeds?
One fix addresses cross-site scripting through Imgur embeds. Patchstack reports that WordPress removed Imgur from its trusted oEmbed providers. That means an Imgur URL is no longer automatically treated as trusted embedded content in the same way.
There is an important cleanup detail: updating core does not necessarily erase previously cached oEmbed records. If your site has embedded Imgur content, clear WordPress caches and review existing embeds after updating. Do not delete legitimate content blindly; check how each affected post renders and replace an embed with a normal link or safe media workflow where needed.
Are older WordPress versions patched?
WordPress says the fixes are being backported, where necessary, to branches eligible for security fixes through WordPress 4.7. The release archive shows new maintenance versions across many older branches on October 6.
However, the same archive states that only the newest 7.1 release is actively maintained. A courtesy security backport is not the same as full ongoing support. If compatibility permits, the clean target is WordPress 7.1.3 rather than remaining indefinitely on an old branch.
| Current situation | Recommended action |
|---|---|
| Already on WordPress 7.1.x | Update to 7.1.3 now |
| On a supported older branch with a new October 6 build | Install that security build, then plan a tested move to 7.1.3 |
| On an older branch without a confirmed patched build | Do not assume it is protected; check the official archive and prepare an upgrade |
| Managed host controls core updates | Confirm the deployed version rather than assuming the host finished |
Our earlier WordPress 7.1 guide explains the major-release changes. Version 7.1.3 is the security update sites on that branch should now run.
How to update WordPress 7.1.3 safely
- Confirm that you can access a recent database and files backup.
- Check available disk space and note the current WordPress, PHP, plugin, and theme versions.
- Update WordPress from Dashboard → Updates, or use your managed deployment process.
- Clear page, object, CDN, and browser caches after the core update.
- Sign out and back in, then confirm the footer or Updates screen reports WordPress 7.1.3.
- Test the homepage, login, editor, comments, forms, checkout or membership flows, scheduled jobs, and REST API integrations relevant to your site.
- Review administrator, Editor, Author, and Contributor accounts and remove access that is no longer required.
WP-CLI users can update with:
wp core update wp core version wp core verify-checksums
Run WP-CLI as the correct website owner, not as an unrestricted root user. A successful checksum check confirms core files match the official package; it does not scan plugins, themes, uploads, or the database for malware.
How do you verify the update worked?
Verification should cover more than the version number. Load the public site in a private browser window, submit and moderate a test comment if comments are enabled, open the editor with a non-administrator test account when your workflow uses one, and check server and PHP logs for new errors.
If an update fails, avoid repeatedly clicking the updater. Preserve the error message, check filesystem permissions and available storage, and use the backup only when you understand what must be restored. On a production site, a short maintenance window is safer than improvising while users are active.
Our assessment: WordPress 7.1.3 deserves a prompt update because it closes multiple independent paths across comments, exports, embeds, roles, and hooks. The evidence does not support treating every site as already compromised, but delaying a routine, available security update adds avoidable risk.
Frequently asked questions
Is WordPress 7.1.3 a security update?
Yes. It contains seven security fixes and four maintenance fixes. WordPress.org recommends updating immediately.
Is WordPress 7.1.3 under active exploitation?
The official release announcement does not say these seven issues are under active exploitation. Update promptly without presenting unconfirmed exploitation as fact.
Will automatic updates install WordPress 7.1.3?
WordPress says sites that support automatic background updates will begin receiving it. Administrators should still verify the installed version on every site.
Do I need to update plugins and themes too?
Core 7.1.3 fixes the listed WordPress core issues. Plugins and themes have separate release and security cycles, so review their updates independently.
