{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/75581?format=json","vulnerability_id":"VCID-r6cv-yqmb-j7gx","summary":"The Social Post Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Threads embed handler in all versions up to, and including, 2.0.1. This is due to insufficient input sanitization and output escaping on the user-supplied URL. 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.","aliases":[{"alias":"CVE-2026-6809"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-6809","reference_id":"","reference_type":"","scores":[{"value":"0.00046","scoring_system":"epss","scoring_elements":"0.14806","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00046","scoring_system":"epss","scoring_elements":"0.14898","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00046","scoring_system":"epss","scoring_elements":"0.14926","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00046","scoring_system":"epss","scoring_elements":"0.14927","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-6809"},{"reference_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4c16841d-8878-4328-a5dc-113d213cca33?source=cve","reference_id":"4c16841d-8878-4328-a5dc-113d213cca33?source=cve","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/4c16841d-8878-4328-a5dc-113d213cca33?source=cve"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L49","reference_id":"threads.php#L49","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L49"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L50","reference_id":"threads.php#L50","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L50"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L61","reference_id":"threads.php#L61","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.2/inc/threads.php#L61"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.1/inc/threads.php#L64","reference_id":"threads.php#L64","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-post-embed/tags/2.0.1/inc/threads.php#L64"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-post-embed/trunk/inc/threads.php#L64","reference_id":"threads.php#L64","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-04-28T12:37:03Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-post-embed/trunk/inc/threads.php#L64"}],"weaknesses":[{"cwe_id":79,"name":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","description":"The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users."}],"exploits":[],"severity_range_score":"6.4 - 6.4","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-r6cv-yqmb-j7gx"}
