CVE-2020-35452 4 Apache, Debian, Fedoraproject and 1 more 6 Http Server, Debian Linux, Fedora and 3 more 2026-06-17 6.8 MEDIUM 7.3 HIGH
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow
CVE-2020-35451 1 Apache 1 Oozie 2026-06-17 1.9 LOW 4.7 MEDIUM
There is a race condition in OozieSharelibCLI in Apache Oozie before version 5.2.1 which allows a malicious attacker to replace the files in Oozie's sharelib during it's creation.
CVE-2020-28052 3 Apache, Bouncycastle, Oracle 20 Karaf, Bc-java, Banking Corporate Lending Process Management and 17 more 2026-06-17 6.8 MEDIUM 8.1 HIGH
An issue was discovered in Legion of the Bouncy Castle BC Java 1.65 and 1.66. The OpenBSDBCrypt.checkPassword utility method compared incorrect data when checking the password, allowing incorrect passwords to indicate they were matching with previously hashed ones that were different.
CVE-2020-27223 5 Apache, Debian, Eclipse and 2 more 16 Nifi, Solr, Spark and 13 more 2026-06-17 4.3 MEDIUM 5.2 MEDIUM
In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of “quality” (i.e. q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values.
CVE-2020-27218 5 Apache, Debian, Eclipse and 2 more 17 Kafka, Spark, Debian Linux and 14 more 2026-06-17 5.8 MEDIUM 4.8 MEDIUM
In Eclipse Jetty version 9.4.0.RC0 to 9.4.34.v20201102, 10.0.0.alpha0 to 10.0.0.beta2, and 11.0.0.alpha0 to 11.0.0.beta2, if GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection, and if an attacker can send a request with a body that is received entirely but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.
CVE-2020-27216 6 Apache, Debian, Eclipse and 3 more 19 Beam, Debian Linux, Jetty and 16 more 2026-06-17 4.4 MEDIUM 7.0 HIGH
In Eclipse Jetty versions 1.0 thru 9.4.32.v20200930, 10.0.0.alpha1 thru 10.0.0.beta2, and 11.0.0.alpha1 thru 11.0.0.beta2O, on Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.
CVE-2020-26259 4 Apache, Debian, Fedoraproject and 1 more 4 Struts, Debian Linux, Fedora and 1 more 2026-06-17 6.4 MEDIUM 6.8 MEDIUM
XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.15, is vulnerable to an Arbitrary File Deletion on the local host when unmarshalling. The vulnerability may allow a remote attacker to delete arbitrary know files on the host as log as the executing process has sufficient rights only by manipulating the processed input stream. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15. The reported vulnerability does not exist running Java 15 or higher. No user is affected, who followed the recommendation to setup XStream's Security Framework with a whitelist! Anyone relying on XStream's default blacklist can immediately switch to a whilelist for the allowed types to avoid the vulnerability. Users of XStream 1.4.14 or below who still want to use XStream default blacklist can use a workaround described in more detailed in the referenced advisories.
CVE-2020-26258 4 Apache, Debian, Fedoraproject and 1 more 4 Struts, Debian Linux, Fedora and 1 more 2026-06-17 5.0 MEDIUM 6.3 MEDIUM
XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.15, a Server-Side Forgery Request vulnerability can be activated when unmarshalling. The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15. The reported vulnerability does not exist if running Java 15 or higher. No user is affected who followed the recommendation to setup XStream's Security Framework with a whitelist! Anyone relying on XStream's default blacklist can immediately switch to a whilelist for the allowed types to avoid the vulnerability. Users of XStream 1.4.14 or below who still want to use XStream default blacklist can use a workaround described in more detailed in the referenced advisories.
CVE-2020-26217 5 Apache, Debian, Netapp and 2 more 15 Activemq, Debian Linux, Snapmanager and 12 more 2026-06-17 9.3 HIGH 8.0 HIGH
XStream before version 1.4.14 is vulnerable to Remote Code Execution.The vulnerability may allow a remote attacker to run arbitrary shell commands only by manipulating the processed input stream. Only users who rely on blocklists are affected. Anyone using XStream's Security Framework allowlist is not affected. The linked advisory provides code workarounds for users who cannot upgrade. The issue is fixed in version 1.4.14.
CVE-2020-25649 6 Apache, Fasterxml, Fedoraproject and 3 more 39 Iotdb, Jackson-databind, Fedora and 36 more 2026-06-17 5.0 MEDIUM 7.5 HIGH

CVE-2020-1964 1 Apache 1 Heron 2026-06-17 7.5 HIGH 9.8 CRITICAL
It was noticed that Apache Heron 0.20.2-incubating, Release 0.20.1-incubating, and Release v-0.20.0-incubating does not configure its YAML parser to prevent the instantiation of arbitrary types, resulting in a remote code execution vulnerabilities (CWE-502: Deserialization of Untrusted Data).
CVE-2020-1963 1 Apache 1 Ignite 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Apache Ignite uses H2 database to build SQL distributed execution engine. H2 provides SQL functions which could be used by attacker to access to a filesystem.
CVE-2020-1961 1 Apache 1 Syncope 2026-06-17 7.5 HIGH 9.8 CRITICAL
Vulnerability to Server-Side Template Injection on Mail templates for Apache Syncope 2.0.X releases prior to 2.0.15, 2.1.X releases prior to 2.1.6, enabling attackers to inject arbitrary JEXL expressions, leading to Remote Code Execution (RCE) was discovered.
CVE-2020-1960 1 Apache 1 Flink 2026-06-17 1.9 LOW 4.7 MEDIUM
A vulnerability in Apache Flink (1.1.0 to 1.1.5, 1.2.0 to 1.2.1, 1.3.0 to 1.3.3, 1.4.0 to 1.4.2, 1.5.0 to 1.5.6, 1.6.0 to 1.6.4, 1.7.0 to 1.7.2, 1.8.0 to 1.8.3, 1.9.0 to 1.9.2, 1.10.0) where, when running a process with an enabled JMXReporter, with a port configured via metrics.reporter.reporter_name>.port, an attacker with local access to the machine and JMX port can execute a man-in-the-middle attack using a specially crafted request to rebind the JMXRMI registry to one under the attacker's control. This compromises any connection established to the process via JMX, allowing extraction of credentials and any other transferred data.
CVE-2020-1959 1 Apache 1 Syncope 2026-06-17 7.5 HIGH 9.8 CRITICAL
A Server-Side Template Injection was identified in Apache Syncope prior to 2.1.6 enabling attackers to inject arbitrary Java EL expressions, leading to an unauthenticated Remote Code Execution (RCE) vulnerability. Apache Syncope uses Java Bean Validation (JSR 380) custom constraint validators. When building custom constraint violation error messages, they support different types of interpolation, including Java EL expressions. Therefore, if an attacker can inject arbitrary data in the error message template being passed, they will be able to run arbitrary Java code.
CVE-2020-1958 1 Apache 1 Druid 2026-06-17 3.5 LOW 6.5 MEDIUM
When LDAP authentication is enabled in Apache Druid 0.17.0, callers of Druid APIs with a valid set of LDAP credentials can bypass the credentialsValidator.userSearch filter barrier that determines if a valid LDAP user is allowed to authenticate with Druid. They are still subject to role-based authorization checks, if configured. Callers of Druid APIs can also retrieve any LDAP attribute values of users that exist on the LDAP server, so long as that information is visible to the Druid server. This information disclosure does not require the caller itself to be a valid LDAP user.
CVE-2020-1957 2 Apache, Debian 2 Shiro, Debian Linux 2026-06-17 7.5 HIGH 9.8 CRITICAL
Apache Shiro before 1.5.2, when using Apache Shiro with Spring dynamic controllers, a specially crafted request may cause an authentication bypass.
