CVE-2020-13935 7 Apache, Canonical, Debian and 4 more 18 Tomcat, Ubuntu Linux, Debian Linux and 15 more 2026-08-25 5.0 MEDIUM 7.5 HIGH
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.
CVE-2020-1938 7 Apache, Blackberry, Debian and 4 more 21 Geode, Tomcat, Good Control and 18 more 2026-08-25 7.5 HIGH 9.8 CRITICAL
When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
CVE-2020-36182 4 Debian, Fasterxml, Netapp and 1 more 45 Debian Linux, Jackson-databind, Cloud Backup and 42 more 2026-08-25 6.8 MEDIUM 8.1 HIGH
FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to org.apache.tomcat.dbcp.dbcp2.cpdsadapter.DriverAdapterCPDS.
CVE-2020-9484 7 Apache, Canonical, Debian and 4 more 26 Tomcat, Ubuntu Linux, Debian Linux and 23 more 2026-08-25 4.4 MEDIUM 7.0 HIGH
When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed.
CVE-2020-24616 4 Debian, Fasterxml, Netapp and 1 more 25 Debian Linux, Jackson-databind, Active Iq Unified Manager and 22 more 2026-08-25 6.8 MEDIUM 8.1 HIGH

CVE-2020-10673 4 Debian, Fasterxml, Netapp and 1 more 31 Debian Linux, Jackson-databind, Steelstore Cloud Integrated Storage and 28 more 2026-08-25 6.8 MEDIUM 8.8 HIGH
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to com.caucho.config.types.ResourceRef (aka caucho-quercus).
CVE-2016-8735 6 Apache, Canonical, Debian and 3 more 19 Tomcat, Ubuntu Linux, Debian Linux and 16 more 2026-08-25 7.5 HIGH 9.8 CRITICAL
Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.
CVE-2020-36187 4 Debian, Fasterxml, Netapp and 1 more 45 Debian Linux, Jackson-databind, Cloud Backup and 42 more 2026-08-25 6.8 MEDIUM 8.1 HIGH
FasterXML jackson-databind 2.x before 2.9.10.8 mishandles the interaction between serialization gadgets and typing, related to org.apache.tomcat.dbcp.dbcp.datasources.SharedPoolDataSource.
CVE-2021-25329 3 Apache, Debian, Oracle 12 Tomcat, Debian Linux, Agile Product Lifecycle Management and 9 more 2026-08-25 4.4 MEDIUM 7.0 HIGH
The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.
CVE-2020-11111 4 Debian, Fasterxml, Netapp and 1 more 25 Debian Linux, Jackson-databind, Steelstore Cloud Integrated Storage and 22 more 2026-08-25 6.8 MEDIUM 8.8 HIGH
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.apache.activemq.* (aka activemq-jms, activemq-core, activemq-pool, and activemq-pool-jms).
CVE-2020-36186 4 Debian, Fasterxml, Netapp and 1 more 45 Debian Linux, Jackson-databind, Cloud Backup and 42 more 2026-08-25 6.8 MEDIUM 8.1 HIGH
