Security readout for executives and security teams
Horde before 2.2.4 allowed a malicious website to obtain a user's session ID from a referrer URL. If the user had an active Horde email session, the attacker could read or create email as that user. The issue is old, but exposed legacy Horde deployments remain business-relevant. Exposure is limited to organizations still running Horde versions before 2.2.4, especially internet-accessible webmail used by authenticated users. The bundle does not identify other affected products or maintained forks. Treat as high priority only if legacy Horde is still present. The business risk is email account compromise, including unauthorized reading and sending of mail. If Horde is absent or fully upgraded, this CVE should be closed as not applicable. Mitigation focus: Upgrade Horde to 2.2.4 or later where legacy deployments remain in use.; Check current vendor or distribution guidance for supported replacement packages.; Retire unsupported Horde instances where patching cannot be verified..
