Descripción técnica

The s2Member – Excellent for All Kinds of Memberships, Content Restriction Paywalls & Member Access Subscriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'date_format' parameter in all versions up to, and including, <= 261011 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload bypasses wp_kses_post() on save because it contains no literal angle brackets — only backslash-escaped sequences that PHP's date() materializes into HTML tag characters at render time after WordPress's shortcode_parse_atts() applies stripcslashes() to the attribute value.

——0A flaw has been found in DataEase up to 2.10.27. Affected by this issue is the function StaticResourceServer.validateSvgContent of the file core/core-backend/src/main/java/io/dataease/visualization/server/StaticResourceServer.java of the component SVG Handler. Executing a manipulation can lead to cross site scripting. It is possible to launch the attack remotely. The exploit has been published and may be used. Upgrading to version 2.10.28 can resolve this issue. This patch is called 0709fe98d6608c3507daee3e92cf433e7ff61370. You should upgrade the affected component. The vendor confirms: "The reported tab/entity-based URL bypass is covered by our previously implemented SVG security hardening. The fix replaces the blacklist-based checks with namespace-aware element and attribute allowlists, restricts permitted references to document-local fragments, and applies a restrictive Content Security Policy to uploaded SVG responses."19h CVE-2026-1234726.5 MED
