5DescriptionCVE.org
The yootheme WordPress theme before 5.0.35 does not prevent its bundled front-end framework from treating certain HTML attributes, which are permitted by wp_kses_post(), as markup, allowing users with the Author role to perform Stored Cross-Site Scripting attacks that execute in the browser of any user who views the affected post.
AnalysisAI
Stored XSS in the yootheme WordPress theme before version 5.0.35 enables users holding the Author role to inject persistent malicious scripts into posts by exploiting a sanitization gap between WordPress's wp_kses_post() filter and the theme's bundled front-end framework, which interprets certain permitted HTML attributes as executable markup. Any visitor - including site administrators - who views an affected post triggers script execution in their browser, creating a realistic privilege escalation path on multi-author WordPress sites. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target WordPress installation must be running the yootheme theme in a version prior to 5.0.35 - no other theme is affected. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 6.8 with PR:H warrants scrutiny. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or obtains an Author account on a WordPress site running a vulnerable version of the yootheme theme, then publishes a post containing HTML attributes that pass wp_kses_post() sanitization but are subsequently interpreted as executable markup by the theme's front-end framework. When a site administrator or other user navigates to the published post, the injected payload executes in their browser, enabling session cookie theft, credential harvesting, or execution of privileged WordPress actions on their behalf. … |
| Remediation | Upgrade the yootheme WordPress theme to version 5.0.35 or later, which is the vendor-confirmed fix per the WPScan advisory (https://wpscan.com/vulnerability/89877758-50f1-4a4b-a622-e417571a5b14/) and EUVD-2026-41252. … Detailed patch versions, workarounds, and compensating controls in full report. |
