CVE-2026-28280Network attack vector

Stored script execution via unsanitized query rendering

Published Feb 26, 2026 · Updated Feb 26, 2026

Stored XSS in JMP Sec osctrl before 0.5.0 allows remote authenticated users to execute JavaScript through saved on-demand queries. The osctrl-admin query list builds DataTables cells from stored query text by string concatenation without HTML escaping, so browsers interpret injected markup as script. Query-level access is sufficient, but execution requires another user to open the list; an administrator's session can expose CSRF tokens and privileged actions.
