Jun 29, 2026APCu Manager: Does not escape APCu object-cache keys before rendering them in an admin-area pageCVE-2026-10083 · WordPress plugins & themes · reported by WPScanHigh 7.5
The APCu Manager WordPress plugin before 4.5.0 does not escape APCu object-cache keys before rendering them in an admin-area page, leading to a Stored Cross-Site Scripting vulnerability. When a persistent object cache is enabled, cache keys derived from unsanitised user input (e.g. a transient name created by another APCu Manager WordPress plugin before 4.5.0 from an unauthenticated request) are output without escaping and execute arbitrary JavaScript in the session of an administrator viewing the page.

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.
