The Rank Math SEO WordPress plugin before 1.0.277 does not verify that a user is allowed to edit the object being modified before updating its SEO indexing metadata, allowing users with the Author role and above to alter that metadata on content, taxonomy terms and user profiles they do not own, and to remove other users' content from the site's sitemap and search engine index.
AnalysisAI
Rank Math SEO WordPress plugin before version 1.0.277 allows any authenticated user with at least the Author role to modify SEO indexing metadata on WordPress content, taxonomy terms, and user profiles they do not own, due to a missing object-ownership check. This enables authors to suppress other users' content from the site's XML sitemap and search engine index, causing targeted de-indexing attacks in multi-author environments. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress session with at least the Author role (Author, Editor, or Administrator). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 2.7 base score (AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N) accurately captures the limited integrity-only impact but the PR:H metric likely overstates the privilege required - WordPress Author is a standard content-contributor role far below administrative level and is conventionally mapped to PR:L in WordPress ecosystem security assessments, which would raise the calculated score modestly. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: 1.0.277. … Detailed patch versions, workarounds, and compensating controls in full report. |
