Security readout for executives and security teams
This is an old reflected XSS issue in Brown Bear Software Calcium web calendar. A malicious link or request could cause a user’s browser to run attacker-supplied script in the calendar site’s context. The sources do not provide CVSS scoring, active exploitation evidence, or a confirmed vendor fix. Exposure is most likely limited to organizations still running Brown Bear Software Calcium 3.10 or 4.0.4, especially public-facing Calcium40.pl calendar endpoints. Modern environments are exposed only if this legacy application remains deployed. Treat this as a legacy application exposure issue. It is not currently evidenced as actively exploited, but public-facing obsolete calendar software can create reputational, session, and data-access risk if still in use. Mitigation focus: Check Brown Bear Software or archive vendor guidance for patches or upgrade paths.; Retire or replace unsupported public Calcium deployments where feasible.; Restrict public access to legacy Calcium instances until risk is resolved..
