CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). |
| CVE-2025-66566 | High | 2025-12-05 | No exploit published | No public exploit | yawkat LZ4 Java provides LZ4 compression for Java. Insufficient clearing of the output buffer in Java-based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data. JNI-based implementations are not affected. This vulnerability is fixed in 1.10.1. |
| CVE-2025-12183 | High | 2025-11-28 | No exploit published | No public exploit | Out-of-bounds memory operations in org.lz4:lz4-java 1.8.0 and earlier allow remote attackers to cause denial of service and read adjacent memory via untrusted compressed input. |
| CVE-2025-59250 | High | 2025-10-14 | No exploit published | No public exploit | Improper input validation in JDBC Driver for SQL Server allows an unauthorized attacker to perform spoofing over a network. |
| CVE-2025-41249 | High | 2025-09-16 | No exploit published | No public exploit | The Spring Framework annotation detection mechanism may not correctly resolve annotations on methods within type hierarchies with a parameterized super type with unbounded generics. This can be an issue if such annotations are used for authorization decisions. Your application may be affected by this if you are using Spring Security's @EnableMethodSecurity feature. You are not affected by this if you are not using @EnableMethodSecurity or if you do not use security annotations on methods in generic superclasses or generic interfaces. This CVE is published in conjunction with CVE-2025-41248 https://spring.io/security/cve-2025-41248 . |
| CVE-2025-41248 | High | 2025-09-16 | No exploit published | No public exploit | The Spring Security annotation detection mechanism may not correctly resolve annotations on methods within type hierarchies with a parameterized super type with unbounded generics. This can be an issue when using @PreAuthorize and other method security annotations, resulting in an authorization bypass. Your application may be affected by this if you are using Spring Security's @EnableMethodSecurity feature. You are not affected by this if you are not using @EnableMethodSecurity or if you do not use security annotations on methods in generic superclasses or generic interfaces. This CVE is published in conjunction with CVE-2025-41249 https://spring.io/security/cve-2025-41249 . |
| CVE-2025-5115 | High | 2025-08-20 | No exploit published | No public exploit | In Eclipse Jetty, versions <=9.4.57, <=10.0.25, <=11.0.25, <=12.0.21, <=12.1.0.alpha2, an HTTP/2 client may trigger the server to send RST_STREAM frames, for example by sending frames that are malformed or that should not be sent in a particular stream state, therefore forcing the server to consume resources such as CPU and memory. For example, a client can open a stream and then send WINDOW_UPDATE frames with window size increment of 0, which is illegal. Per specification https://www.rfc-editor.org/rfc/rfc9113.html#name-window_update , the server should send a RST_STREAM frame. The client can now open another stream and send another bad WINDOW_UPDATE, therefore causing the server to consume more resources than necessary, as this case does not exceed the max number of concurrent streams, yet the client is able to create an enormous amount of streams in a short period of time. The attack can be performed with other conditions (for example, a DATA frame for a closed stream) that cause the server to send a RST_STREAM frame.

| CVE-2025-48989 | High | 2025-08-13 | No exploit published | No public exploit | Improper Resource Shutdown or Release vulnerability in Apache Tomcat made Tomcat vulnerable to the made you reset attack. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.9, from 10.1.0-M1 through 10.1.43 and from 9.0.0.M1 through 9.0.107. Older, EOL versions may also be affected. Users are recommended to upgrade to one of versions 11.0.10, 10.1.44 or 9.0.108 which fix the issue. |
| CVE-2025-52520 | High | 2025-07-10 | No exploit published | No public exploit | For some unlikely configurations of multipart upload, an Integer Overflow vulnerability in Apache Tomcat could lead to a DoS via bypassing of size limits. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.8, from 10.1.0-M1 through 10.1.42, from 9.0.0.M1 through 9.0.106. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 through 8.5.100. Other, older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.9, 10.1.43 or 9.0.107, which fix the issue. |
| CVE-2025-52999 | High | 2025-06-25 | No exploit published | No public exploit | jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large. jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. As a workaround, users should avoid parsing input files from untrusted sources. |
| CVE-2025-48976 | High | 2025-06-16 | No exploit published | No public exploit | Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in Apache Commons FileUpload. This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from 2.0.0-M1 before 2.0.0-M4. Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the issue. |
| CVE-2024-13009 | High | 2025-05-08 | No exploit published | No public exploit | In Eclipse Jetty versions 9.4.0 to 9.4.56 a buffer can be incorrectly released when confronted with a gzip error when inflating a request body. This can result in corrupted and/or inadvertent sharing of data between requests. |
| CVE-2025-22228 | High | 2025-03-20 | No exploit published | No public exploit | BCryptPasswordEncoder.matches(CharSequence,String) will incorrectly return true for passwords larger than 72 characters as long as the first 72 characters are the same. |
