Descrição técnica

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, POSIX xonsh activation quote() uses repr() to write printable non-ASCII prompt or destination data into UTF-8 activate.xsh, while xonsh can read that script using $XONSH_ENCODING. Under a legacy multibyte codec such as GBK or Big5, a UTF-8 trail byte can consume the backslash before an adjacent quote, allowing the literal to close and attacker-influenced statements to execute when the user sources the generated script. This issue is fixed in version 21.14.9.

——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."16h CVE-2026-1209849.1 CRÍ

——0A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during the setup process. This allows an authenticated attacker with client management permissions to bypass security controls and upload a malicious JavaScript policy, which is then executed on the server when an authorization request is made. Successful exploitation could allow the attacker to run arbitrary code on the server, potentially compromising the entire system.20h CVE-2026-1025646.5 MÉD

——0The The Dynific Addons for Elementor (formerly Anywhere Elementor) plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.3.0 This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires the target site to have a public post rendered through an AE template that includes the AE Post Comments widget, and for the attacker's comment to be visible on that page — a barrier removed once the attacker has a previously approved comment or when comment moderation is relaxed.22h CVE-2026-1039176.5 MÉD

——6The The Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 11.2.7. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The submission nonce is dispensed to any unauthenticated caller by the public wp_ajax_nopriv_qsm_create_quiz_nonce endpoint, meaning it functions as a CSRF token rather than an authorization barrier and imposes no meaningful obstacle to exploitation.1d CVE-2026-1214919.0 CRÍ

——4The Fiber Admin WordPress plugin before 4.0.1 does not validate or escape a request header before writing it into a PHP file it regenerates on an unprotected admin hook, allowing unauthenticated attackers to execute arbitrary code when its custom database error page is enabled and they win a race against an administrator saving its settings.15h CVE-2026-173599.9 CRÍ

——18IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to execute arbitrary code due to improper control of generation of code. A user-supplied value can influence code that the product generates, which could lead to code execution.1d
