Keycloak 26.6.x < 26.6.6 Multiple Vulnerabilities

The version of Keycloak installed on the remote host is 26.6.x prior to 26.6.6. It is, therefore, affected by multiple vulnerabilities: - A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak. The mechanism used to protect the account-linking process from unauthoriz...

CVE-2026-15571

A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC...

CVE-2026-15571

Keycloak's legacy client-initiated account-linking endpoint uses a predictable hash to protect against unauthorized requests. A malicious OIDC client can forge a valid linking URL after tricking a victim to authenticate, connecting the victim's account to the attacker's external identity and enab...

PT-2026-67467

osTicket 1.18.3 generates API keys using a predictable construction based on MD5 hashing. The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the ke...

EUVD-2026-30736

The Autoptimize WordPress plugin before 3.1.15, Clearfy Cache WordPress plugin before 2.4.2, Speed Optimizer WordPress plugin before 7.7.9 are vulnerable to unauthenticated Stored Cross-Site Scripting XSS due to a predictable replacement hash used during the HTML minification process and abusing ...

CVE-2026-5084 WebDyne::Session versions before 3.003_704 for Perl generate the session id insecurely

WebDyne::Session versions before 3.003704 for Perl generate the session id insecurely. The session handler generates the session id from an MD5 hash seeded with a call to the built-in rand function. The rand function is passed a maximum value based on the process id, the epoch time and the...

Magento LTS has Weak API Session ID — Predictable MD5 of Time-Derived Inputs

Affected Version: OpenMage LTS ≤ 20.16.0 confirmed on 20.16.0 Affected File: https://github.com/OpenMage/magento-lts/blob/main/app/code/core/Mage/Api/Model/Session.php – start method Summary The XML-RPC / SOAP API session ID is generated using an outdated, time-based construction rather than a...

nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions

A flaw was found in V8's string hashing mechanism within Node.js. A remote attacker can exploit this vulnerability by crafting requests containing integer-like strings. These specially crafted strings cause predictable hash collisions in V8's internal string table, particularly when processed by...

OpenML Frontend 安全漏洞

OpenML Frontend is an OpenML Frontend page from OpenML Open Source. A security vulnerability exists in OpenML Frontend version v2.0.20241110, which stems from the use of predictable MD5-based tokens that could lead to account takeover...

CVE-2025-25183 vLLM using built-in hash() from Python 3.12 leads to predictable hash collisions in vLLM prefix cache

vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Maliciously constructed statements can lead to hash collisions, resulting in cache reuse, which can interfere with subsequent responses and cause unintended behavior. Prefix caching makes use of Python's built-i...

GHSA-RM76-4MRF-V9R8 vLLM uses Python 3.12 built-in hash() which leads to predictable hash collisions in prefix cache

Summary Maliciously constructed prompts can lead to hash collisions, resulting in prefix cache reuse, which can interfere with subsequent responses and cause unintended behavior. Details vLLM's prefix caching makes use of Python's built-in hash function. As of Python 3.12, the behavior of hashNon...

CVE-2024-47188

Suricata (IDS/IPS/NSM engine) is affected by CVE-2024-47188 and related 7.x/8.x issues. PTSecurity entries describe heap overflow in logging verdict information (eve.alert/eve.drop) for Suricata versions prior to 7.0.13 and prior to 8.0.2, potentially crashing the process. A workaround mentioned ...

CVE-2024-47187 Suricata datasets: missing hashtable random seed leads to potential DoS

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to datasets having predictable hash table behavior. This can lead to dataset file loading to us...
