Multiple race conditions in HtmlCleaner before 2.6, as used in Open-Xchange AppSuite 7.2.2 before rev13 and other products, allow remote authenticated users to read the private e-mail of other persons in opportunistic circumstances by leveraging lack of thread safety and performing a rapid series of (1) mail-sending or (2) draft-saving operations.

Security readout for executives and security teams

This flaw could let a logged-in user see someone else’s private email when rapid mail-send or draft-save actions hit a race condition. The cited issue affects HtmlCleaner before 2.6 and Open-Xchange AppSuite 7.2.2 before rev13. The main business risk is email confidentiality loss in legacy deployments. Exposure is most plausible in legacy Open-Xchange AppSuite 7.2.2 builds before rev13 or products bundling HtmlCleaner before 2.6. The source bundle does not identify specific additional products, deployment prevalence, or supported-version status. Treat as a priority legacy confidentiality issue if Open-Xchange AppSuite or bundled HtmlCleaner is present. It is not enough to rely on perimeter controls because the described attacker is already authenticated. Mitigation focus: Upgrade HtmlCleaner to version 2.6 or later where directly used.; Upgrade Open-Xchange AppSuite 7.2.2 to rev13 or later.; Identify products bundling HtmlCleaner and check vendor guidance..
