CVE-2026-73157
Overview
CVE-2026-73157 is a known-severity vulnerability. It was published on August 11, 2026.
Technical Description
Affected versions of cti-transmute render data obtained from a remote MISP instance into the event-browser interface using HTML interpolation. Because fields such as event IDs, event information, organization names, tags, tag colors, TLP labels, distribution labels, and error/flash text may be controlled by the remote MISP server, a malicious or compromised remote instance could return crafted values that inject HTML or script-capable content into the cti-transmute interface.
The patch explicitly notes that remote-derived values must not reach innerHTML, and replaces string-built rows and badges with DOM nodes populated through textContent. It also restricts remote-controlled tag colors to six-digit hexadecimal values, preventing malicious CSS values such as url(...).
