A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.3, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.14 and 7.4 GA through update 92 allows an remote authenticated attacker to inject JavaScrip in the _com_liferay_users_admin_web_portlet_UsersAdminPortlet_assetTagNames parameter

A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.3, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.14 and 7.4 GA through update 92 allows an remote non-authenticated attacker to inject JavaScript in web content for friendly urls.

A stored DOM-based Cross-Site Scripting (XSS) vulnerability in Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.5, 2025.Q1.0 through 2025.Q1.15, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.19 and 7.4 GA through update 92 exists in the Asset Publisher configuration UI within the Source.js module. This vulnerability allows attackers to inject arbitrary JavaScript via DDM structure field labels which are then inserted into the DOM using innerHTML without proper encoding.

A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.8 and 2025.Q1.0 through 2025.Q1.15 allows a remote authenticated user to inject JavaScript code via _com_liferay_journal_web_portlet_JournalPortlet_backURL parameter.

### Summary In the default configuration of mermaid 11.9.0, user supplied input for sequence diagram labels is passed to `innerHTML` during calculation of element size, causing XSS. ### Details Sequence diagram node labels with KaTeX delimiters are passed through `calculateMathMLDimensions`. This method passes the full label to `innerHTML` which allows allows malicious users to inject arbitrary HTML and cause XSS when mermaid-js is used in it's default configuration (with KaTeX support enabled). The vulnerability lies here: ```ts export const calculateMathMLDimensions = async (text: string, config: MermaidConfig) => { text = await renderKatex(text, config); const divElem = document.createElement('div'); divElem.innerHTML = text; // XSS sink, text has not been sanitized. divElem.id = 'katex-temp'; divElem.style.visibility = 'hidden'; divElem.style.position = 'absolute'; divElem.style.top = '0'; const body = document.querySelector('body'); body?.insertAdjacentElemen...

### Summary In the default configuration of mermaid 11.9.0, user supplied input for architecture diagram icons is passed to the d3 `html()` method, creating a sink for cross site scripting. ### Details Architecture diagram service `iconText` values are passed to the d3 `html()` method, allowing malicious users to inject arbitrary HTML and cause XSS when mermaid-js is used in it's default configuration. The vulnerability lies here: ```ts export const drawServices = async function ( db: ArchitectureDB, elem: D3Element, services: ArchitectureService[] ): Promise<number> { for (const service of services) { /** ... **/ } else if (service.iconText) { bkgElem.html( `<g>${await getIconSVG('blank', { height: iconSize, width: iconSize, fallbackPrefix: architectureIcons.prefix })}</g>` ); const textElemContainer = bkgElem.append('g'); const fo = textElemContainer .append('foreignObject') .attr('width', iconSize) .attr('he...

A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q2.0 through 2025.Q2.8, 2025.Q1.0 through 2025.Q1.15, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13 and 2024.Q1.1 through 2024.Q1.19 allows a remote authenticated user to inject JavaScript code via _com_liferay_expando_web_portlet_ExpandoPortlet_displayType parameter. Liferay Portal is fixed on the master branch from commit acc4771.

### Summary In affected versions of `astro`, the image optimization endpoint in projects deployed with on-demand rendering allows images from unauthorized third-party domains to be served. ### Details On-demand rendered sites built with Astro include an `/_image` endpoint which returns optimized versions of images. The `/_image` endpoint is restricted to processing local images bundled with the site and also supports remote images from domains the site developer has manually authorized (using the [`image.domains`](https://docs.astro.build/en/reference/configuration-reference/#imagedomains) or [`image.remotePatterns`](https://docs.astro.build/en/reference/configuration-reference/#imageremotepatterns) options). However, a bug in impacted versions of `astro` allows an attacker to bypass the third-party domain restrictions by using a protocol-relative URL as the image source, e.g. `/_image?href=//example.com/image.png`. ### Proof of Concept 1. Create a new minimal Astro project (`as...
