Technical description

A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

CVE-2026-121632—

———Data::MuForm versions through 0.05 for Perl render attribute values and option labels into HTML without escaping. process_attrs writes each attribute value into the markup as is. The select, radio group and checkbox group renderers pass each option to it, so an option's value becomes an unescaped attribute. Option and option group labels are also unescaped, the group label inside a label attribute and the others in element content. Any application whose option list is built from data rather than literals, using an options_<field_name> method, a build_options method or a DBIC model, allows attacker-influenced text in an option value or label that can embed JavaScript in rendered pages. Attribute values built from data, such as through element_attr, are affected the same way.5h CVE-2026-121008—

———SQL::Abstract::Tree versions before 2.000001_04 for Perl allow cross-site scripting via unescaped SQL text and bind values in the html profile. The html profile wraps keywords and placeholders in span elements and breaks lines with br elements, so its output is meant to go into a page as is. The format method does not HTML-escape the SQL text or the bind values it fills in around that markup. An application that renders SQL formatted with the html profile, such as in a debug panel or query log, allows an attacker who controls a bind value or part of the SQL text to embed JavaScript in the page.5h CVE-2026-1204216.1 MED

———In Eclipse Mojarra versions 2.2.0 through 4.0.28, 4.1.0 through 4.1.19, and 5.0.0-M1 through 5.0.0-M11, when URL client window mode is enabled (`jakarta.faces.CLIENT_WINDOW_MODE=url`), the client window id from the `jfwid` or `jakarta.faces.ClientWindow` request parameter is appended to generated URLs without URL-encoding. `h:button` renders such a URL into a JavaScript string literal, which allows reflected cross-site scripting. With `com.sun.faces.enableCspNonce=true`, the injected script runs on page load inside the nonce script element, bypassing the Content Security Policy.5h CVE-2026-114627—

———Web::Simple versions before 0.036 for Perl do not escape values interpolated into double-quoted strings in HTML::Tags output. Under use HTML::Tags or use XML::Tags, a double-quoted string literal becomes a StringThing object that holds each interpolated value as a separate part. The escaping step passes such objects through, and stringify joins their interpolated parts as is. A value passed on its own, as in <p>, $value, </p>, is entity-escaped, but the same value in "Hello $value" is not. An attacker who controls a value that an application interpolates into a double-quoted string can inject script into the generated page.5h CVE-2026-1194687.1 HIG

———The Remove Google Fonts – Disable, Block, or Replace with Bunny Fonts for GDPR Compliance plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Field via Regex-Mangled Output Buffer in all versions up to, and including, 1.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires the plugin's Remove mode to be active and the malicious comment to be published, either through auto-approval for known commenters or manual moderator approval.4h
