PDF_JBIG2_ACTIVE_CONTENT
What it means
PDF uses JBIG2Decode/JBIG2 data alongside active content.
Why it fires
JBIG2 plus active content is a high-value parser-exploit indicator for families including CVE-2021-30860 and CVE-2009-0658. The rule matches /JBIG2Decode or JBIG2 signatures plus active content such as JavaScript, XFA, or RichMedia; it does not uniquely identify either CVE.
