Users Anywhere (usersanywhere) below 2.0.0 - SSRF, Stored XSS and Sensitive Data Exposure

Regular Labs Users Anywhere before 2.0.0 is affected by issues fixed in the coordinated Regular Labs security release of 22 July 2026 (no CVE assigned): external image downloads accepting unsafe hosts, redirects, non-image responses or local download folders (SSRF); tag-provided field custom HTML overrides able to render unsafe markup (stored XSS); and tags able to expose authentication data or restricted contact details. Several fixes are BC breaks (field custom HTML now renders as escaped text). Update to Users Anywhere 2.0.0 or later. CVE ids assigned by the Joomla CNA for this extension in the 22 July 2026 Regular Labs security release: CVE-2026-64794, CVE-2026-64795, CVE-2026-64799, CVE-2026-65755.

MediumCVE-2026-851962026-09-13

Users Anywhere (usersanywhere) 2.0.0 to below 2.1.0 - Authenticated Stored and Reflected XSS via Unescaped Request Input

Regular Labs Users Anywhere 2.0.0 through 2.0.6 is affected by CVE-2026-85196, fixed in 2.1.0 (released 13 September 2026). Request input consumed by Users Anywhere data tags was not escaped, and the optional raw output mode was available to any article author, allowing script to be injected into rendered content. This is the same defect and the same CVE the vendor fixed in Articles Anywhere 20.0.0, the two extensions sharing the data-tag code. Exploitation requires the ability to author or edit content containing Users Anywhere tags, or a page that already feeds request input into one. Update to 2.1.0 or later. The CVE record was published on 14 September 2026 with a CVSS 4.0 base score of 5.3 (Medium), vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N.

Affected versions: ≥ 2.0.0 and < 2.1.0
