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 sanitize_text_field callback applied on save does not strip double-quote characters or on* event-handler attributes, and the output filter Vk_Call_To_Action::safe_kses_post() only rewrites disallowed iframe elements while returning all other content verbatim, leaving the injected payload intact in the rendered HTML."}],"title":"VK All in One Expansion Unit <= 9.118.0 - Authenticated (Author+) Stored Cross-Site Scripting via 'vkExUnit_cta_img_position' Post Meta","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/04b9c0c4-3f1a-4984-9b24-6de3dc78bde0?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.118.0/inc/call-to-action/package/block/index.php#L281"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.118.0/inc/block-editor-panels/enqueue.php#L195"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.118.0/inc/call-to-action/package/class-vk-call-to-action.php#L747"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.118.0/inc/call-to-action/package/view-actionbox.php#L72"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.116.0/inc/call-to-action/package/block/index.php#L281"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.116.0/inc/block-editor-panels/enqueue.php#L195"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.116.0/inc/call-to-action/package/class-vk-call-to-action.php#L747"},{"url":"https://plugins.trac.wordpress.org/browser/vk-all-in-one-expansion-unit/tags/9.116.0/inc/call-to-action/package/view-actionbox.php#L72"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3631372%40vk-all-in-one-expansion-unit&new=3631372%40vk-all-in-one-expansion-unit"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Kyokito"},{"lang":"en","type":"finder","value":"Athiwat Tiprasaharn (Jitlada)"},{"lang":"en","type":"finder","value":"Itthidej Aramsri (Boeing777)"}],"timeline":[{"time":"2026-09-17T18:47:48.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-18T14:37:01.052086Z","id":"CVE-2026-17586","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-18T14:42:33.350Z"}}]}}
