WebApp JSP Snoop page XSS in jetty though 6.1.21.

XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 via an about: page, as demonstrated by ephy-about:overview when a user visits an XSS payload page often enough to place that page on the Most Visited list.

JSP Dump and Session Dump Servlet XSS in jetty before 6.1.22.

Zabbix before 3.0.32rc1, 4.x before 4.0.22rc1, 4.1.x through 4.4.x before 4.4.10rc1, and 5.x before 5.0.2rc1 allows stored XSS in the URL Widget.

In Action View before versions 5.2.4.4 and 6.0.3.3 there is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped. This is patched in versions 6.0.3.3 and 5.2.4.4. A workaround without upgrading is proposed in the source advisory.

Cross-site scripting (XSS) vulnerability in the tag cloud search script (horde/services/portal/cloud_search.php) in Horde before 3.2.4 and 3.3.3, and Horde Groupware before 1.1.5, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Horde IMP before 4.2.2 and 4.3.3 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors to (1) smime.php, (2) pgp.php, and (3) message.php.

The default error page for VelocityView in Apache Velocity Tools prior to 3.1 reflects back the vm file that was entered as part of the URL. An attacker can set an XSS payload file as this vm file in the URL which results in this payload being executed. XSS vulnerabilities allow attackers to execute arbitrary JavaScript in the context of the attacked website and the attacked user. This can be abused to steal session cookies, perform requests in the name of the victim or for phishing attacks.

An issue was discovered in Roundcube Webmail before 1.3.12 and 1.4.x before 1.4.5. include/rcmail_output_html.php allows XSS via the username template object.

An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. Query parameters generated by the Django admin ForeignKeyRawIdWidget were not properly URL encoded, leading to a possibility of an XSS attack.

Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1.x before 1.1.14 allows remote attackers to bypass the same origin policy and conduct cross-site scripting (XSS) attacks via an XBL binding to an "unloaded document."

Unspecified vulnerability in the session-restore feature in Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19 allows remote attackers to bypass the same origin policy, inject content into documents associated with other domains, and conduct cross-site scripting (XSS) attacks via unknown vectors related to restoration of SessionStore data.

An issue was discovered in Roundcube Webmail before 1.4.4. There is a cross-site scripting (XSS) vulnerability in rcube_washtml.php because JavaScript code can occur in the CDATA of an HTML message.

GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code.

In affected versions of WordPress, a vulnerability in the stats() method of class-wp-object-cache.php can be exploited to execute cross-site scripting (XSS) attacks. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).

In Kaminari before 1.2.1, there is a vulnerability that would allow an attacker to inject arbitrary code into pages with pagination links. This has been fixed in 1.2.1.

In jQuery starting with 1.12.0 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.

This has been patched in WordPress 5.3.1, along with all the previous WordPress versions from 3.7 to 5.3 via a minor release.

http_protocol.c in (1) IBM HTTP Server 6.0 before 6.0.2.13 and 6.1 before 6.1.0.1, and (2) Apache HTTP Server 1.3 before 1.3.35, 2.0 before 2.0.58, and 2.2 before 2.2.2, does not sanitize the Expect header from an HTTP request when it is reflected back in an error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated using a Flash SWF file.

Roundcube before 1.4.14, 1.5.x before 1.5.4, and 1.6.x before 1.6.3 allows XSS via text/plain e-mail messages with crafted links because of program/lib/Roundcube/rcube_string_replacer.php behavior.

WordPress before 5.2.4 is vulnerable to a stored XSS attack to inject JavaScript into STYLE elements.

DOMPurify before 2.0.1 allows XSS because of innerHTML mutation XSS (mXSS) for an SVG element or a MATH element, as demonstrated by Chrome and Safari.

WordPress before 5.2.3 allows XSS in media uploads because wp_ajax_upload_attachment is mishandled.

Roundcube before 1.4.13 and 1.5.x before 1.5.2 allows XSS via an HTML e-mail message with crafted Cascading Style Sheets (CSS) token sequences.

XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 when View Source mode or Reader mode is used, as demonstrated by a a page title.

Wikimedia MediaWiki 1.30.0 through 1.32.1 has XSS. Loading user JavaScript from a non-existent account allows anyone to create the account, and perform XSS on users loading that script. Fixed in 1.32.2, 1.31.2, 1.30.2 and 1.27.6.

Roundcube before 1.3.17 and 1.4.x before 1.4.12 is prone to XSS in handling an attachment's filename extension when displaying a MIME type warning message.

dojox is vulnerable to Cross-site Scripting in all versions before version 1.16.1, 1.15.2, 1.14.5, 1.13.6, 1.12.7 and 1.11.9. This is due to dojox.xmpp.util.xmlEncode only encoding the first occurrence of each character, not all of them.

jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of various `*Text` options of the Datepicker widget from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. The values passed to various `*Text` options are now always treated as pure text, not HTML. A workaround is to not accept the value of the `*Text` options from untrusted sources.
