Mermaid: Improper sanitization of configuration leads to CSS injection

Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. Prior to 10.9.6 and 11.15.0, Mermaid's default configuration allows injecting CSS that applies outside of the Mermaid diagram via the fontFamily, themeCSS, and altFontFamily configuration options. The injected CSS exploits stylis's & (scope reference) handling. :not(&) escapes the #mermaid-xxx automatic scoping, applying styles to all page elements. Global at-rules (@font-face, @keyframes, @counter-style) are also injectable as stylis hoists them to top level. This allows page defacement and DOM attribute exfiltration via CSS :has() selectors. This vulnerability is fixed in 10.9.6 and 11.15.0.

WP Photo Album Plus <= 9.1.13.005 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'subtext' Shortcode Attribute

The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'subtext' parameter in all versions up to, and including, 9.1.13.005 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. A contributor-level attacker can embed the malicious [photo] shortcode in a post submitted for review, causing the stored payload to execute when an administrator or any other user views the post.

Stored cross-site scripting vulnerability in GitHub Enterprise Server allowed arbitrary JavaScript execution via crafted Discussion titles in the Q&A category

A stored cross-site scripting vulnerability was identified in GitHub Enterprise Server that allowed an authenticated attacker to execute arbitrary JavaScript in another user's browser by injecting a crafted payload into the title of a Discussion in the Q&A category. The AnsweredQuestionStructuredDataComponent did not escape user-controlled Discussion titles before embedding them in a <script type="application/ld+json"> block, allowing the title to break out of the script context. The injection was escalated to a full cross-site scripting attack on GitHub Enterprise Server by leveraging JSONP callback support in the REST API to bypass the Content Security Policy. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.21 and was fixed in versions 3.20.4, 3.19.8, 3.18.11, 3.17.17, 3.16.20. This vulnerability was reported via the GitHub Bug Bounty program.

Cross-site Scripting in StoneFly Storage Concentrator

Storage Concentrator (SC & SCVM) is vulnerable to reflected cross-site scripting due to unsanitized content being echoed back in 404 error pages. An attacker can craft a malicious URL that, when visited by an authenticated user, causes arbitrary script content to execute within the victim's browser session in the context of the application. This could be leveraged to steal session cookies, redirect users, or perform unauthorized actions on behalf of the victim.

SeaweedFS < 4.30 - Cross-Origin Information Disclosure via Unvalidated JSONP callback Parameter

SeaweedFS before 4.30 reflects the callback query parameter verbatim into responses served with Content-Type application/javascript in the shared writeJson helper (weed/server/common.go), with no callback-name validation, no X-Content-Type-Options: nosniff header, and no CORS allow-list. Every JSON endpoint that uses writeJson - including the unauthenticated master endpoints /dir/status, /dir/lookup and /cluster/status, the volume server /status, and the filer directory listing, all reachable in the default configuration (no -whiteList, no security.toml, bound to 0.0.0.0) - can therefore be loaded cross-origin via a script tag with a chosen callback, letting a third-party web page read cluster topology, volume server URLs and gRPC ports, file identifiers, and directory listings. Because the callback string is reflected at the start of the body and no nosniff header is sent, MIME-sniffing clients may also interpret the reflected content as HTML.

FV Flowplayer Video Player <= 7.5.51.7212 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'video_player' Shortcode

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'video_player' shortcode 'align' attribute in all versions up to, and including, 7.5.51.7212 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

ColdFusion | Cross-site Scripting (Reflected XSS) (CWE-79)

ColdFusion versions 2025.9, 2023.20 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially resulting in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious link. Scope is changed.

LearnPress <= 4.4.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'class_wrapper_form' Shortcode Attribute

The LearnPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class_wrapper_form' shortcode attribute in versions up to, and including, 4.4.0. This is due to insufficient input sanitization and output escaping in the FilterCourseTemplate::sections() method at line 98, where the attacker-controlled attribute is inserted into an HTML class attribute via sprintf('<form class="%s">', $class_wrapper_form) without esc_attr() escaping. The FilterCourseShortcode::render() handler does not apply shortcode_atts() filtering, so raw user attributes flow directly through do_action('learn-press/filter-courses/layout', $data) into the template. 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.

Flowise - Session Hijacking via Weak Default Express Session Secret

Flowise before 3.1.0 (affected versions 3.0.13 and earlier) uses a weak hardcoded default secret ('flowise') for the express-session middleware when the EXPRESS_SESSION_SECRET environment variable is not set (packages/server/src/enterprise/middleware/passport/index.ts). Because this default secret is publicly visible in the source code, an attacker can forge valid signed session cookies to impersonate any user and bypass authentication.

WP Google Review Slider <= 18.1 - Reflected Cross-Site Scripting via 'place' Parameter

The Wp Google Places Review Slider plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'place' parameter in versions up to, and including, 18.1. This is due to insufficient input sanitization and output escaping in admin/partials/googlecrawl_dfs.php, where the $_GET['place'] value is URL-decoded, stripslashes()'d, and echoed directly into an HTML value attribute with no esc_attr() call when the supplied place is not already a stored key in the wprev_google_crawls option. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.

This is due to insufficient output escaping and missing server-side validation of the Animated Box widget's animation_effect setting before it is rendered inside an HTML class attribute. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
