Descrição técnica

Conda Organization Infrastructure is a centralized location for infrastructure codes. Prior to commit 9c0f238, a GitHub Actions Pwn Request vulnerability appears to remain present in conda/conda. The affected workflow is .github/workflows/update.yml. It is triggered by issue_comment events containing @conda-bot render or @conda-bot recreate. For the render path, the workflow obtains the pull request head repository and branch from the PR API, checks out that PR-controlled repository/ref using secrets.SYNC_TOKEN, and then runs conda/actions/template-files@7f6830b1428a9bd47f0b068892c77eae95207037. The external template-files action reads its default configuration and templates from the checked-out working directory. In the confirmed finding, that action uses an unsandboxed Jinja2 environment to render attacker-controlled template content. This creates a Pwn Request chain in which an untrusted PR/comment path can reach template rendering in a privileged token context. This issue has been patched via commit 9c0f238.

———A vulnerability has been found in FlowCI flow-core-x up to 1.23.49. The affected element is the function ConditionManagerImpl.run of the file core/src/main/java/com/flowci/core/common/manager/ConditionManagerImpl.java of the component Groovy Script Evaluation. The manipulation of the argument condition leads to code injection. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.6h CVE-2026-1239924.3 MÉD

——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."23h 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.1d 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.1d 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.22h
