    The mechanism binding API-uploaded files to the uploader's authentication method is not working correctly and the same session token is used for all token-based API users. Since API-uploaded files are refered to by randomly generated UUIDs and only exist for a day, there is virtually no risk, but it renders the added protection mechanism useless.

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.
