CVE-2026-1205974.3 MED—
——0A vulnerability was identified in Welcart e-Commerce Plugin up to 2.12.6 on WordPress. This affects the function ESCOTT_MAIN::error_page_message of the file classes/paymentESCOTT.main.class.php. Such manipulation of the argument ResponseCd leads to cross site scripting. The attack can be launched remotely. The exploit is publicly available and might be used. Upgrading to version 2.12.7 mitigates this issue. It is recommended to upgrade the affected component. The value is now escaped with esc_html() before output. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.16hCVE-2026-865969.8 CRÍ—
——0The s2Member plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, <= 260927 via the 'item_name' parameter parameter. This is due to insufficient sanitization in strip_php_tags_deep(), which only strips literal '<?' sequences, combined with a post-interpolation placeholder cleanup that reassembles a valid '<?php' opener after the attacker-controlled value has already been embedded in the email template. This makes it possible for authenticated attackers, with custom-level access and above, to execute code on the server.17hCVE-2026-105600——
——0Joomla Extension - php-web-design.com - RCE via setting strings in StageIt 1.0-5.7.5, 6.0-6.3.522hCVE-2026-102802——
——0Joomla Extension - regularlabs.com - PHP code injection vector in Sourcerer extension < 17.0.1 when used with Articles Anywhere extension < 20.1.1 - Sourcerer can restrict PHP in articles according to article-author trust; the exact creator and last-editor rule varies by release. Articles Anywhere can insert the text or full layout of one article into another. In the affected combination, when Articles Anywhere processes an inclusion before Sourcerer and Force Content Triggers is off, the included article's Sourcerer code can be evaluated using the enclosing article's trusted identity rather than the included article's own identity. The resulting gap is between the authority of the article supplying the code and the authority used to decide whether to run it. Ordinary Articles Anywhere output is not itself the issue.22hCVE-2026-1203497.3 ALT—
