Cross-site scripting in Znuny's AgentTicketEmailResend template allows a high-privileged authenticated attacker to inject malicious script that executes within other agents' browser sessions, enabling session hijacking or unauthorized agent-level actions. All Znuny LTS versions prior to 6.5.22 are affected per CPE cpe:2.3:a:znuny:znuny:*:*:*:*:*:*:*:* and the vendor advisory at znuny.org/en/advisories/zsa-2026-12. No public exploit or active exploitation has been identified at time of analysis; the high privilege requirement substantially constrains the realistic threat surface.
Reflected cross-site scripting in Znuny's AdminCommunicationLog (communication log administration view) allows a low-privileged authenticated attacker to inject arbitrary JavaScript that executes in the context of other users' browsers, with changed scope indicating impact beyond the vulnerable component itself. Affected releases are Znuny LTS before 6.5.21 and Znuny before 7.3.3. No public exploit identified at time of analysis and this CVE does not appear in CISA KEV, though the low-complexity, network-accessible attack vector and changed scope elevate practical concern for deployments with untrusted low-privilege users.
Stored cross-site scripting in Znuny's user preferences mechanism allows an authenticated low-privileged attacker to inject persistent malicious scripts that execute in other users' browsers, crossing security boundaries (S:C) to potentially compromise administrator sessions or perform unauthorized actions on their behalf. Both the LTS branch (before 6.5.21) and the main release branch (before 7.3.3) are affected. Vendor-released patches exist for both branches; no public exploit identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog.
