CVE-2025-13836: Excessive Read Buffering DoS in HTTP Client
Executive Summary
CVE-2025-13836 describes a vulnerability in the Python `http.client` module that can lead to a denial-of-service (DoS) attack. The vulnerability occurs when reading an HTTP response, and no read amount is specified, causing the client to read large amounts of data into memory.
Vulnerability Details
Affected Product: Python `http.client` module
Identifier: CVE-2025-13836
CVSS Score: Medium (CVSS v3.1: 5.3)
Exploitation Status: Undergoing analysis
Risk & Impact
Triage: Immediate action is recommended to mitigate the risk of potential DoS attacks.
Attack Vector: A malicious server sends a large or crafted Content-Length header, causing the client to read excessive data into memory.
Ease of Exploit: Exploitation is possible if the application uses the `http.client.HTTPResponse.read` function without specifying a byte limit and connects to a malicious server.
Action Plan
Immediate Action: Apply a mitigation by imposing an explicit, safe limit on data reads when using the `http.client.HTTPResponse.read` function. Upgrade to Python 3.14.2 or 3.13.11. (Strictly avoid 3.14.1 as it is superseded and potentially unstable).
Workaround: Specify a read amount when making HTTP requests to avoid relying on the Content-Length header.
Detection: Monitor traffic for suspicious Content-Length headers and excessive memory usage by Python applications.
Relevant professional terms
Denial of Service (DoS)
A cyber-attack that aims to make a machine or network resource unavailable to its intended users by flooding it with excessive requests or exploiting weaknesses in protocols.
HTTP client

CISA Orders Federal Agencies to Patch Actively Exploited MongoBleed Flaw
High
Executive Summary
CISA has ordered U.S. federal agencies to patch the MongoBleed vulnerability, CVE-2025-14847, which is being actively exploited to potentially steal credentials, API keys, and other sensitive data. This vulnerability is a high-severity unauthenticated memory leak affecting MongoDB.
Vulnerability Details
Affected Product: MongoDB Server versions since 2017 are potentially affected. Specifically, versions 4.4, 5.0, 6.0, 7.0, and 8.0 branches are impacted. Patches have been released for versions 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, and 4.4.30.
Identifier: CVE-2025-14847
CVSS Score: 8.7 (High)
Exploitation Status: Actively Exploited
Risk & Impact
Triage: Immediate patching or mitigation is required due to the high risk of sensitive data exposure.
Attack Vector: The vulnerability is triggered by sending specially crafted compressed payloads to a vulnerable MongoDB server, causing it to miscalculate the length of decompressed data and return unintended memory contents. This is done by exploiting the zlib compression handling logic.
Ease of Exploit: Public proof-of-concept exploit code is available, making exploitation easier. The vulnerability can be exploited without authentication, requiring only network access to the MongoDB service port.
Action Plan
Immediate Action: Upgrade to MongoDB versions 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, and 4.4.30.
Workaround: Disable zlib compression if patching cannot be immediately performed. Restrict network access to trusted IPs only.
Detection: Monitor logs for bursty connections with missing metadata from suspicious IPs. Look for malformed compressed requests, abnormal response sizes, and unusual protocol behavior. Use tools like Velociraptor and mongobleed-detector to identify exploitation attempts.
Relevant professional terms
Heap Memory
Dynamically allocated memory used by a program during its execution. It is used for storing data structures and objects, and its contents can include sensitive information.
Zlib Compression
A data compression library used to reduce the size of data for efficient network transfer. The MongoBleed vulnerability arises from improper handling of length parameter inconsistencies in the zlib compression protocol headers.

The Shai Hulud 2.0 campaign compromises the npm supply chain by targeting developer environments and CI/CD pipelines to harvest credentials and secrets. The goal is to steal credentials and secrets from cloud platforms and developer services, automating the backdooring of NPM packages.
Key TTPs
Initial Access: Compromised npm packages via malicious preinstall scripts.
Execution: Executes malicious code during the preinstall phase using setup_bun.js to load bun_environment.js.
Defense Evasion: Utilizes the preinstall hook to execute payloads before security checks.
Campaign Analysis
Shai-Hulud 2.0 introduces automation, faster propagation, and a broader target set compared to its predecessor. It compromises hundreds of packages and creates thousands of malicious GitHub repositories, leading to widespread credential theft and potential data breaches.
Targeting & Infrastructure
Target Profile: Targets developers, CI/CD pipelines, and cloud-connected workloads.
Infrastructure: Leverages compromised npm packages and GitHub repositories for credential exfiltration and backdoor access.
Actionable Intelligence
Domains: [github[.]com]
Relevant Terms
NPM: A package manager for JavaScript, used to share and manage code dependencies.

Ransomware attacks are becoming more sophisticated and impactful, leveraging AI to enhance their capabilities and target vulnerable systems, with the weekend being a prime time for attacks. Organizations must adapt their defenses to address these evolving threats.
Key Findings
Over half of organizations experienced ransomware attacks during weekends or holidays, exploiting periods of reduced vigilance.
From January to June 2025, publicly reported ransomware victims jumped by 70% compared to the same period in 2023 and 2024.
Only 23% of ransomware victims paid in Q3 2025, a historic low, indicating a growing resistance to paying ransoms.
The Bottom Line
The evolving ransomware landscape demands a proactive and adaptive security posture. Organizations must prioritize AI-driven security solutions, enhance incident response capabilities, and foster a culture of cyber resilience to effectively counter increasingly sophisticated attacks. Focusing on prevention, detection, and rapid response is crucial to minimizing the impact of ransomware incidents.
Relevant Terms
Ransomware-as-a-Service (RaaS): A business model where ransomware developers lease their tools to other cybercriminals, lowering the barrier to entry for launching attacks.
AI-Driven Phishing: The use of artificial intelligence to create highly convincing and personalized phishing emails, making them harder to detect.
