Critical 9.8
Undertow client not checking server identity presented by server certificate in https connections
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.

Remote Code execution in SnakeYAML
SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrust…

High 7.5
Denial of Service (DoS)
The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections.

High 7.5
Undertow: infinite loop in sslconduit during close
A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.

Stack exhaustion in json-smart leads to denial of service when parsing malformed JSON
[Json-smart](https://netplex.github.io/json-smart/) is a performance focused, JSON processor lib. When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively. It was discovered that the code does not have any lim…

High 7.5CVE-2023-20860 Public exploit
Spring Framework is vulnerable to security bypass via mvcRequestMatcher pattern mismatch
Spring Framework running version 6.0.0 - 6.0.6 or 5.3.0 - 5.3.25 using "**" as a pattern in Spring Security configuration with the mvcRequestMatcher creates a mismatch in pattern matching between Spring Security and Spring MVC, and the potential for a securit…

DoS in SnakeYAML
Using snakeYAML to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow.

Spring Framework vulnerable to denial of service via specially crafted SpEL expression
In Spring Framework versions 6.0.0 - 6.0.6, 5.3.0 - 5.3.25, 5.2.0.RELEASE - 5.2.22.RELEASE, and older unsupported versions, it is possible for a user to provide a specially crafted SpEL expression that may cause a denial-of-service (DoS) condition.

Qemu: 9pfs: improper access control on special files
A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. The 9pfs server did not prohibit opening special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a dev…

Stack Overflow in Snakeyaml
Those using Snakeyaml to parse untrusted YAML files may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stack overflow. This effect may suppor…
