    Amavis before 2.12.3 and 2.13.x before 2.13.1, in part because of its use of MIME-tools, has an Interpretation Conflict (relative to some mail user agents) when there are multiple boundary parameters in a MIME email message. Consequently, there can be an incorrect check for banned files or malware.

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.
