What we check for

HighCVE-2026-1007512026-09-27

Tabs & Accordions (tabsaccordions) 2.3.0 to below 3.2.0 - Authenticated Stored XSS via JavaScript URLs in data-rlta-url Attributes

Regular Labs Tabs & Accordions 3.0.0 through 3.1.x is affected by a security issue fixed in 3.2.0 (released 27 September 2026). data-rlta-url attributes accepted executable JavaScript URLs, so script supplied by a content author ran in the browser of a visitor who used the tab or accordion. Exploitation requires the ability to author or edit content, so this is an authenticated stored XSS. The vendor tags the fix PRO, so Free installs on the same version numbers are unlikely to be affected, but mySites.guru cannot tell the two editions apart by version number and flags both. Update to 3.2.0 or later. This is a separate issue from the data-rlta-alias XSS fixed in 3.1.0, so sites that updated to 3.1.0 on 13 September need to update again. No CVE record for this fix has been published yet.

Affected versions: ≥ 2.3.0 and < 3.2.0

HighCVE-2026-851912026-09-13

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. The CVE record was published on 14 September 2026 with a CVSS 4.0 base score of 7.5 (High), vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/S:N/AU:N.

Affected versions: ≥ 3.0.0 and < 3.1.0
