Sep 18, 2026VK All in One Expansion Unit: Stored Cross-Site ScriptingCVE-2026-17586 · WordPress plugins & themes · reported by WordfenceMedium 6.4
The VK All in One Expansion Unit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'vkExUnit_cta_img_position' Post Meta in all versions up to, and including, 9.118.0 due to insufficient input sanitization and output escaping. 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.

Nov 18, 2025VK All in One Expansion Unit: Stored Cross-Site ScriptingCVE-2025-11265 · WordPress plugins & themes · reported by WordfenceMedium 6.4
The VK All in One Expansion Unit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vkExUnit_cta_url' and 'vkExUnit_cta_button_text' parameters in all versions up to, and including, 9.112.1.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
