Liferay Portal 7.4.0 through 7.4.3.101, and Liferay DXP 2023.Q3.0 through 2023.Q3.4, 7.4 GA through update 92 and 7.3 GA though update 35 does not limit the number of objects returned from a GraphQL queries, which allows remote attackers to perform denial-of-service (DoS) attacks on the application by executing queries that return a large number of objects.

### Summary A flaw in the `bodyLimit` middleware could allow bypassing the configured request body size limit when conflicting HTTP headers were present. ### Details The middleware previously prioritized the `Content-Length` header even when a `Transfer-Encoding: chunked` header was also included. According to the HTTP specification, `Content-Length` must be ignored in such cases. This discrepancy could allow oversized request bodies to bypass the configured limit. Most standards-compliant runtimes and reverse proxies may reject such malformed requests with `400 Bad Request`, so the practical impact depends on the runtime and deployment environment. ### Impact If body size limits are used as a safeguard against large or malicious requests, this flaw could allow attackers to send oversized request bodies. The primary risk is denial of service (DoS) due to excessive memory or CPU consumption when handling very large requests. ### Resolution The implementation has been updated to alig...

A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in the Hugging Face Transformers library, specifically affecting the MarianTokenizer's `remove_language_code()` method. This vulnerability is present in version 4.52.4 and has been fixed in version 4.53.0. The issue arises from inefficient regex processing, which can be exploited by crafted input strings containing malformed language code patterns, leading to excessive CPU consumption and potential denial of service.

Microsoft on Tuesday addressed a set of 80 security flaws in its software, including one vulnerability that has been disclosed as publicly known at the time of release. Of the 80 vulnerabilities, eight are rated Critical and 72 are rated Important in severity. None of the shortcomings has been exploited in the wild as a zero-day. Like last month, 38 of the disclosed flaws are related to

### Overview A security review of the Cattown identified multiple weaknesses that could potentially impact its stability and security. ### Affected Versions - All versions below 1.0.2 ### Description of Vulnerabilities 1. CWE-1333: Inefficient Regular Expression Complexity The package used regular expressions with inefficient, potentially exponential worst-case complexity. This can cause excessive CPU usage due to excessive backtracking on crafted inputs, potentially leading to denial of service. 2. CWE-400: Uncontrolled Resource Consumption (Resource Exhaustion) The package was vulnerable to resource exhaustion, where processing malicious inputs could cause high CPU or memory usage, potentially leading to denial of service. ### Impact - Trigger excessive CPU consumption leading to denial of service - Cause resource exhaustion affecting service availability - Bypass protection mechanisms causing unexpected or insecure behavior ### Resolution These vulnerabilities have been fixed in...
