This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability occurs because the plugin uses a custom wp_kses implementation with permissive allowed HTML tags, and then performs a str_replace operation that injects HTML after sanitization, allowing event handlers to be introduced through the %total placeholder in the style attribute.","published_at":"2026-05-28T08:27:38.853000Z","last_modified_at":null,"cvss_v3_score":6.4,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e037d22a-3d4d-4f70-a749-6d6c552c7553?source=cve","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1143","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1144","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L965","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L868","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3532532%40shariff&new=3532532%40shariff&sfp_email=&sfph_mail="],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:24.582923Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"3uu","vendor_name":"3uu","product_slug":"shariff-wrapper","product_name":"Shariff Wrapper","version_start":"0","version_start_inclusive":true,"version_end":"4.6.20","version_end_inclusive":true,"cpe23_uri":"cve5:3uu:shariff-wrapper:0:4.6.20"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e037d22a-3d4d-4f70-a749-6d6c552c7553?source=cve","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1143","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1144","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L965","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L868","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3532532%40shariff&new=3532532%40shariff&sfp_email=&sfph_mail=","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-05-28T08:27:38.853000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:17.036284Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:17.036284Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:17.036284Z","label":"CVSS score revised","source":"cvelistv5"}]}
