Tabs & Accordions (tabsaccordions) 3.0.0 to below 3.1.0 - Authenticated Stored XSS via Crafted data-rlta-alias Attributes
Regular Labs Tabs & Accordions 3.0.0 through 3.0.5 is affected by CVE-2026-85191, fixed in 3.1.0 (released 13 September 2026). Crafted data-rlta-alias attributes were not sanitised, so JavaScript ran when a matching link was clicked. Exploitation requires the ability to author or edit content containing a Tabs & Accordions link, so this is an authenticated stored XSS that fires on visitor interaction rather than on page load. Update to 3.1.0 or later. 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: ≥ 3.0.0 and < 3.1.0
