CVE-2023-1024: WP Meta SEO <= 4.5.3 - Missing Authorization in 'regenerateSitemaps'

The WP Meta SEO plugin for WordPress is vulnerable to unauthorized sitemap generation due to a missing capability check on the regenerateSitemaps function in versions up to, and including, 4.5.3. This makes it possible for authenticated attackers with subscriber-level access to generate sitemaps. This vulnerability occurred as a result of the plugin relying on nonce checks as a means of access control, and that nonce being accessible to all authenticated users regardless of role.

Security readout for executives and security teams

Plain-English summary

WP Meta SEO for WordPress allowed any logged-in user, including subscribers, to trigger sitemap regeneration in versions up to 4.5.3. This is not a data-theft issue, but it can let low-privileged accounts make unauthorized site-output changes that may affect SEO operations or publishing controls.

Executive priority

Treat as a moderate WordPress governance issue. It is unlikely to create immediate breach impact alone, but it weakens role-based control over SEO behavior and should be remediated during normal plugin security maintenance, faster on sites with open registration.

Technical view

CVE-2023-1024 is CWE-862 missing authorization in WP Meta SEO's regenerateSitemaps function. The plugin relied on nonce validation as access control, but the nonce was available to all authenticated users. CVSS 3.1 is 4.3: network reachable, low complexity, low privileges, no user interaction, integrity impact only.

Likely exposure

Exposure is limited to WordPress sites running WP Meta SEO versions up to and including 4.5.3, where untrusted or broadly distributed authenticated accounts exist. Sites without the plugin, without affected versions, or without low-privileged users are less exposed.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation evidence. The attacker needs authenticated subscriber-level access, so this is most relevant to membership, customer portal, community, or public-registration WordPress sites.

Researcher notes

The core issue is authorization confusion: nonce presence was treated as sufficient, but nonces were accessible to all authenticated roles. The useful validation focus is role/capability enforcement around regenerateSitemaps, not payload behavior. Source evidence names subscriber-level access and integrity-only impact.

Mitigation direction

  • Inventory WordPress sites for WP Meta SEO versions up to 4.5.3.
  • Update WP Meta SEO beyond affected versions after confirming vendor release guidance.
  • Temporarily disable the plugin if no safe update path is available.
  • Restrict untrusted subscriber-level accounts until remediation is complete.
  • Review plugin changelog for added capability checks on sitemap regeneration.

Validation and detection

  • Confirm whether WP Meta SEO is installed and record its version.
  • Identify sites allowing public registration or untrusted subscriber accounts.
  • Verify sitemap regeneration requires an appropriate administrative capability.
  • Review logs for unexpected sitemap regeneration by low-privileged users.
  • Confirm remediation against vendor guidance or the referenced WordPress changeset.
