Technical description

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via registration metadata in all versions up to, and including, 6.3.1 This is due to insufficient escaping in `ExceptionalElements::image_element()`, which concatenates a user-meta value straight into an `<img src="…">` attribute. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute whenever a user accesses a page rendering a Kirki users collection whose image element is bound to one of the nine registration meta fields. Requires public user registration to be enabled and a published page carrying a `kirki-register` element, which prints the required element nonce into the public markup.

———Improper Neutralization of Input During Web Page Generation (“Cross-site Scripting”) in ASUS router modules allows a remote attacker to read DOM information, modify router settings, and cause a denial-of-service condition when an authenticated user visits a crafted URL.Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information.13h CVE-2026-96594—

——0The Gitea API endpoint `GET /api/v1/repos/{owner}/{repo}/media/{filepath}` wrote files of up to 1 KiB that are stored directly in Git, not in LFS, to the response without the content type and disposition headers Gitea uses for user content. An HTML file committed to a repository was therefore rendered by the browser on the Gitea origin. A user who can push to a repository could run JavaScript in the session of a victim who opens the media URL and act with the victim's permissions.18h CVE-2026-1051114.7 MED

——0Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Apache Commons BCEL. This only happens when you're using Class2HTML to generate webpages for possibly-attacker-controlled class files, where Class2HTML emitters write attacker class-file strings into HTML unescaped (stored XSS in reports). This issue affects Apache Commons BCEL: before 6.13.0. Users are recommended to upgrade to version 6.13.0, which fixes the issue.9h CVE-2026-103667—

——0Gitea's container registry served blob downloads with a `Content-Type` taken from the media type declared in pushed image manifests, without a `Content-Disposition` or restrictive content security policy. A user who can push container images can publish a blob containing HTML and JavaScript with a `text/html` media type. When a victim who is authenticated to the instance opens the blob URL in a browser, the script runs on the Gitea origin and can perform actions as the victim, such as creating API tokens.20h CVE-2026-1011588.4 HIG

——0A missing input validation vulnerability in the Fileserver upload API allows an authenticated attacker with file upload privileges to execute stored cross-site scripting (XSS). Successful exploitation could enable the attacker to hijack another CloudVision user's web session, potentially granting full access to their account and administrative permissions.20h CVE-2026-1011578.7 HIG

——0A stored cross-site scripting (XSS) vulnerability may allow an unauthenticated attacker with adjacent-network access to inject malicious content that executes when an authenticated user views affected content. Successful exploitation may allow the attacker to compromise the victim's authenticated browser session, access sensitive data, modify system state, or disrupt affected services.19h
