Summary

Interpretation conflict between Internet Explorer and other web browsers such as Mozilla, Opera, and Firefox might allow remote attackers to modify the visual presentation of web pages and possibly bypass protection mechanisms such as content filters via ASCII characters with the 8th bit set, which could be stripped by Internet Explorer to render legible text, but not when using other browsers. NOTE: there has been significant discussion about this issue, and as of 20060625, it is not clear where the responsibility for this issue lies, although it might be due to vagueness within the associated standards. NOTE: this might only be exploitable with certain encodings.

Exploit prediction

13.53% chance of exploitation in the next 30 days, higher than 96% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns 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.
