Bugzilla 2.20rc1 through 2.20 and 2.21.1, when using RSS 1.0, allows remote attackers to conduct cross-site scripting (XSS) attacks via a title element with HTML encoded sequences such as ">", which are automatically decoded by some RSS readers. NOTE: this issue is not in Bugzilla itself, but rather due to design or documentation inconsistencies within RSS, or implementation vulnerabilities in RSS readers. While this issue normally would not be included in CVE, it is being identified since the Bugzilla developers have addressed it.

Security readout for executives and security teams

This issue affects older Bugzilla RSS 1.0 output and can expose users to cross-site scripting through RSS reader behavior. The CVE notes the weakness is tied to RSS design or reader handling, not Bugzilla core, but Bugzilla developers still addressed it. Exposure is likely limited to organizations running the listed Bugzilla versions with RSS 1.0 feeds consumed by vulnerable or permissive RSS readers. Treat as a legacy exposure cleanup item unless old Bugzilla RSS 1.0 feeds are still in use. Prioritize remediation for internet-facing trackers or teams using RSS readers heavily. Mitigation focus: Identify Bugzilla instances running 2.20rc1 through 2.20 or 2.21.1.; Apply Bugzilla vendor updates or fixes referenced by the Bugzilla security advisory.; Review whether RSS 1.0 feeds are enabled and needed..
