CVE-2026-55864	High	2026-09-15	Mitigation candidate	Working exploit published	GeoNetwork is a catalog application to manage spatially referenced resources. Prior to 4.2.17 and 4.4.12, POST /api/tools/ogc/sld accepted a caller-supplied WMS server URL and performed a server-side HTTP GET without destination validation. An anonymous attacker could make the GeoNetwork server send requests to internal hosts that are not publicly reachable. When the outbound response was XML, the endpoint could store and return the fetched body, making the request forgery non-blind and enabling internal data disclosure, authorization bypass, and network reconnaissance. This issue is fixed in versions 4.2.17 and 4.4.12.
CVE-2025-27817	High	2025-06-10	Mitigation candidate	Exploited	A possible arbitrary file read and SSRF vulnerability has been identified in Apache Kafka Client. Apache Kafka Clients accept configuration data for setting the SASL/OAUTHBEARER connection with the brokers, including "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url". Apache Kafka allows clients to read an arbitrary file and return the content in the error log, or sending requests to an unintended location. In applications where Apache Kafka Clients configurations can be specified by an untrusted party, attackers may use the "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url" configuratin to read arbitrary contents of the disk and environment variables or make requests to an unintended location. In particular, this flaw may be used in Apache Kafka Connect to escalate from REST API access to filesystem/environment/URL access, which may be undesirable in certain environments, including SaaS products. Since Apache Kafka 3.9.1/4.0.0, we have added a system property ("-Dorg.apache.kafka.sasl.oauthbearer.allowed.urls") to set the allowed urls in SASL JAAS configuration. In 3.9.1, it accepts all urls by default for backward compatibility. However in 4.0.0 and newer, the default value is empty list and users have to set the allowed urls explicitly.
CVE-2025-27888	Medium	2025-03-20	Mitigation candidate	Working exploit published	Severity: medium (5.8) / important Server-Side Request Forgery (SSRF), Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Apache Druid. This issue affects all previous Druid versions. When using the Druid management proxy, a request that has a specially crafted URL could be used to redirect the request to an arbitrary server instead. This has the potential for XSS or XSRF. The user is required to be authenticated for this exploit. The management proxy is enabled in Druid's out-of-box configuration. It may be disabled to mitigate this vulnerability. If the management proxy is disabled, some web console features will not work properly, but core functionality is unaffected. Users are recommended to upgrade to Druid 31.0.2 or Druid 32.0.1, which fixes the issue.
CVE-2023-43795	Critical	2023-10-25	Mitigation candidate	Exploited	GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. The OGC Web Processing Service (WPS) specification is designed to process information from any server using GET and POST requests. This presents the opportunity for Server Side Request Forgery. This vulnerability has been patched in version 2.22.5 and 2.23.2.
CVE-2022-46364	Critical	2022-12-13	Mitigation candidate	Proof of concept only	A SSRF vulnerability in parsing the href attribute of XOP:Include in MTOM requests in versions of Apache CXF before 3.5.5 and 3.4.10 allows an attacker to perform SSRF style attacks on webservices that take at least one parameter of any type.
CVE-2022-40146	High	2022-09-22	Mitigation candidate	Proof of concept only	Server-Side Request Forgery (SSRF) vulnerability in Batik of Apache XML Graphics allows an attacker to access files using a Jar url. This issue affects Apache XML Graphics Batik 1.14.
CVE-2021-39152	High	2021-08-23	Mitigation candidate	Exploited	XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the [Security Framework](https://x-stream.github.io/security.html#framework), you will have to use at least version 1.4.18.
CVE-2020-10770	Medium	2020-12-15	Mitigation candidate	Exploited	A flaw was found in Keycloak before 13.0.0, where it is possible to force the server to call out an unverified URL using the OIDC parameter request_uri. This flaw allows an attacker to use this parameter to execute a Server-side request forgery (SSRF) attack.
