Title
zcaceres markdownify-mcp webpage-to-markdown Markdownify.ts saveToTempFile random values
Summary
A flaw has been found in zcaceres markdownify-mcp up to 1.1.0. This impacts the function saveToTempFile of the file src/Markdownify.ts of the component webpage-to-markdown/youtube-to-markdown/bing-search-to-markdown. This manipulation causes insufficiently random values. The attack is restricted to local execution. A high degree of complexity is needed for the attack. The exploitability is said to be difficult. The exploit has been published and may be used. The pull request to fix this issue awaits acceptance.

CVE-2026-14570 (GCVE-0-2026-14570)

Vulnerability from cvelistv5 – Published: 2026-07-05 01:30 – Updated: 2026-07-06 13:42

Title
Crypt::DSA versions before 1.22 for Perl draw the DSA signing nonce and private key from a biased random generator, leading to private-key recovery
Summary
Crypt::DSA versions before 1.22 for Perl draw the DSA signing nonce and private key from a biased random generator, leading to private-key recovery. "Crypt::DSA::Util::makerandom forces the high bit of every value it returns to obtain an exactly N-bit integer for prime search. The signing nonce and the private key are drawn from makerandom. Because the high bit is always set, the result is not uniform: its top bit is fixed, producing insecure values." An attacker who collects a modest number of signatures under an affected key, together with the public key, can recover the private key with a lattice attack. Keys used to sign with an affected version should be considered compromised and new keys should be generated.

CVE-2026-12272 (GCVE-0-2026-12272)

Vulnerability from cvelistv5 – Published: 2026-10-16 05:30 – Updated: 2026-10-16 17:06

Title
Lightweight Cookie Notice <= 1.19 - Sensitive Information Exposure via W3TC_DYNAMIC_SECURITY Constant
Summary
The Lightweight Cookie Notice – Cookie Banner for Cookie Consent plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.19 This is due to the W3TC_DYNAMIC_SECURITY constant being hardcoded to a publicly known value. This makes it possible for unauthenticated attackers to know the W3 Total Cache mfunc security key, which when W3 Total Cache is installed may allow arbitrary PHP code injection.
Severity
5.3 (Medium)

Title
chatchat-space Langchain-Chatchat Uploaded File openai_routes.py _get_file_id random values
Summary
A vulnerability was found in chatchat-space Langchain-Chatchat up to 0.3.1.3. The affected element is the function _get_file_id of the file libs/chatchat-server/chatchat/server/api_server/openai_routes.py of the component Uploaded File Handler. Performing a manipulation results in insufficiently random values. Access to the local network is required for this attack. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2026-3416 (GCVE-0-2026-3416)

Vulnerability from cvelistv5 – Published: 2026-09-03 12:35 – Updated: 2026-09-03 12:55

Title
Predictable Pseudorandom Number Generation via Webhook HMAC Secret Generation in Multiple WSO2 Products Allows Forged Event Payloads
Summary
The API Publisher component previously used a non-cryptographic pseudorandom number generator (PRNG) to create shared secrets for Webhook HMAC validation. This PRNG lacks sufficient entropy for security-sensitive operations, allowing a sophisticated attacker to predict future secrets. This enables malicious actors to forge event payloads with valid HMAC signatures, bypassing the API Gateway's authenticity verification. Successful exploitation could allow an attacker to predict shared secrets used for Webhook HMAC validation and forge event payloads with valid signatures. This may enable bypassing API Gateway authenticity checks, leading to unauthorized event injection, data manipulation, or downstream system compromise.

Mitigation
Architecture and Design
  • Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds.
  • In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts.
  • Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a "random enough" number.
Mitigation
Implementation

Consider a PRNG that re-seeds itself as needed from high quality pseudo-random output sources, such as hardware devices.

Mitigation MIT-2
Architecture and Design Requirements

Strategy: Libraries or Frameworks

Use products or modules that conform to FIPS 140-2 [REF-267] to avoid obvious entropy problems. Consult FIPS 140-2 Annex C ("Approved Random Number Generators").

CAPEC-112: Brute Force

In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset.

CAPEC-485: Signature Spoofing by Key Recreation

An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

CAPEC-59: Session Credential Falsification through Prediction

This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
