      <title>GHSA-r29c-68gh-xp6x — Apache Tomcat - HTTP/2 request headers not validated</title>
      <link>https://db.gcve.eu/vuln/ghsa-r29c-68gh-xp6x</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Maven: org.apache.tomcat.embed:tomcat-embed-core, Maven: org.apache.tomcat:tomcat, Maven: org.apache.tomcat:tomcat-coyote&lt;/p&gt;
&lt;p&gt;Versions Affected:
Apache Tomcat 11.0.0-M1 to 11.0.21
Apache Tomcat 10.1.0-M1 to 10.1.54
Apache Tomcat 9.0.0.M1 to 9.0.117
Older, unsupported versions may also be affected&lt;/p&gt;
&lt;p&gt;Description:
HTTP/2 request headers were not validated which may have triggered
unexpected application behaviour if the application (quite reasonably)
assumed that header value exposed through the Servlet API would be
specification compliant.&lt;/p&gt;
&lt;p&gt;Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 11.0.22 or later
- Upgrade to Apache Tomcat 10.1.55 or later
- Upgrade to Apache Tomcat 9.0.118 or later&lt;/p&gt;
