Articles Anywhere (articlesanywhere) 19.0.0 to below 20.1.1 - Authenticated PHP Execution via Included Articles when Sourcerer is also installed
CVE-2026-102802 (CVE record reserved, not yet published). When Regular Labs Sourcerer is installed alongside Articles Anywhere, an article included through an Articles Anywhere tag had its Sourcerer PHP run under the trust of the HOST article rather than its own author. A content author whose own articles are not trusted to run Sourcerer PHP could therefore get their PHP executed by having their article pulled into a trusted article (for example by a category or latest-articles listing). Sites without Sourcerer are not affected by this issue. The fix is joint: update Articles Anywhere to 20.1.1 or later AND Sourcerer to 17.0.1 or later (31 October 2026); updating only one of the two leaves the site exposed. Free and Pro editions are both affected. Temporary mitigation: restrict which user groups can create or edit articles, or disable Sourcerer PHP in articles until both extensions are updated.
Affected versions: ≥ 19.0.0 and < 20.1.1
