CVE Severity Published▾ Status Exploitation Description
CVE-2025-54988 Critical 2025-08-20 Protected by Waratek Exploited Critical XXE in Apache Tika (tika-parser-pdf-module) in Apache Tika 1.13 through and including 3.2.1 on all platforms allows an attacker to carry out XML External Entity injection via a crafted XFA file inside of a PDF. An attacker may be able to read sensitive data or trigger malicious requests to internal resources or third-party servers. Note that the tika-parser-pdf-module is used as a dependency in several Tika packages including at least: tika-parsers-standard-modules, tika-parsers-standard-package, tika-app, tika-grpc and tika-server-standard. Users are recommended to upgrade to version 3.2.2, which fixes this issue.
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-2021-45105 Medium 2021-12-18 Protected by Waratek Exploited Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.
