Detection & IOCs extracted from sources · hover to see the quote

• → Trigger involves a crafted DOM structure with a float:left element containing a complex element styled with 'float:left; width:100%' and a ':first-line { clear:left }' pseudo-element, combined with nested position:fixed, position:relative, table, and unknown elements, followed by a dynamic class attribute change via setAttribute to provoke the out-of-bounds read in MSHTML SRunPointer::SpanQualifier/RunType ↗

• · The PoC as published only demonstrates an out-of-bounds read (crash/DoS); it does not include a working RCE payload, so in-the-wild exploitation for code execution would require additional heap-shaping/shellcode not present in this sample ↗
