Modals (modals) 16.0.0 to below 17.0.0 - Authenticated Stored XSS via JavaScript URLs and JavaScript Events
Regular Labs Modals 16.0.0 through 16.2.0 is affected by two vendor-confirmed security defects, both fixed in 17.0.0 (released 13 September 2026). CVE-2026-85189: modal links accepted javascript: URLs, so a crafted link executed script when the modal was opened. CVE-2026-88853: JavaScript Events could be attached by any user able to author content; 17.0.0 restricts them to selected article author groups by default. Both require the ability to author or edit content containing Modals links or tags, making this an authenticated stored XSS. Update to 17.0.0 or later. Note that 17.0.0 is flagged by the vendor as a BC BREAK: the JavaScript Events restriction is enabled by default and has to be re-opened deliberately per author group, so review those settings after updating. As at 13 September 2026 the CVE record(s) for this advisory are RESERVED and not yet published, so no official CVSS score exists yet and the severity recorded here is mySites.guru's own assessment, to be revised when the records go live.
Affected versions: ≥ 16.0.0 and < 17.0.0
