CWE-79

Wagtail is an open source content management system built on Django. A cross-site scripting vulnerability exists in versions 2.13-2.13.1, versions 2.12-2.12.4, and versions prior to 2.11.8. When the `{% include_block %}` template tag is used to output the value of a plain-text StreamField block (`CharBlock`, `TextBlock` or a similar user-defined block derived from `FieldBlock`), and that block does not specify a template for rendering, the tag output is not properly escaped as HTML. This could allow users to insert arbitrary HTML or scripting. This vulnerability is only exploitable by users with the ability to author StreamField content (i.e. users with ‘editor’ access to the Wagtail admin). Patched versions have been released as Wagtail 2.11.8 (for the LTS 2.11 branch), Wagtail 2.12.5, and Wagtail 2.13.2 (for the current 2.13 branch). As a workaround, site implementors who are unable to upgrade to a current supported version should audit their use of `{% include_block %}` to ensure it is not used to output `CharBlock` / `TextBlock` values with no associated template. Note that this only applies where `{% include_block %}` is used directly on that block (uses of `include_block` on a block _containing_ a CharBlock / TextBlock, such as a StructBlock, are unaffected). In these cases, the tag can be replaced with Django’s `{{ … }}` syntax – e.g. `{% include_block my_title_block %}` becomes `{{ my_title_block }}`.

wire-webapp is the web version of Wire, an open-source messenger. A cross-site scripting vulnerability exists in wire-webapp prior to version 2021-06-01-production.0. If a user is instructed to open an image in a new tab (right click -> open in new tab, or copy the URL and paste it in the URL bar), an the image payload is executed on the domain hosting the app (app.wire.com). In particular, if an image contains malicious code in addition to the actual picture, this code is executed on app.wire.com. This allows the attacker to fully control the user account. The vulnerability was patched in version 2021-06-01-production.0. As a workaround, users should not try to open image URLs.

Multiple improper neutralization of input during web page generation (CWE-79) in FortiManager and FortiAnalyzer versions 7.0.0, 6.4.5 and below, 6.2.7 and below user interface, may allow a remote authenticated attacker to perform a Stored Cross Site Scripting attack (XSS) by injecting malicious payload in GET parameters.

An improper neutralization of input during web page generation vulnerability (CWE-79) in FortiPortal GUI 6.0.4 and below, 5.3.6 and below, 5.2.6 and below, 5.1.2 and below, 5.0.3 and below, 4.2.2 and below, 4.1.2 and below, 4.0.4 and below may allow a remote and unauthenticated attacker to perform an XSS attack via sending a crafted request with an invalid lang parameter or with an invalid org.springframework.web.servlet.i18n.CookieLocaleResolver.LOCALE value.

Share/IncomingWizard.htm in SolarWinds Serv-U before 15.2.3 mishandles the user-supplied SenderEmail parameter, aka “Share URL XSS.”

Apache Superset up to and including 1.1 does not sanitize titles correctly on the Explore page. This allows an attacker with Explore access to save a chart with a malicious title, injecting html (including scripts) into the page.
