Summary
Microsoft Internet Explorer 6, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, as demonstrated by Stephen Fewer as the first of three chained vulnerabilities during a Pwn2Own competition at CanSecWest 2011, aka "Object Management Memory Corruption Vulnerability."
Exploit prediction
40.88% chance of exploitation in the next 30 days, higher than 98% of all scored CVEs (FIRST EPSS, 2026-11-09).

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
