| CVE-2024-4027 | Hig | 0.42 | 7.5 | 0.00 | Jan 30, 2026 | A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack. | ||
| CVE-2024-3884 | Hig | 0.42 | 7.5 | 0.00 | Dec 3, 2025 | A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack. | ||
| CVE-2025-60537 | Med | 0.42 | 6.5 | 0.00 | Oct 14, 2025 | Improper input validation in the component /kafka/ui/serdes/CustomSerdeLoader.java of kafka-ui v0.6.0 to v0.7.2 allows attackers to execute arbitrary code via supplying crafted data. | ||
| CVE-2025-62162 | Hig | 0.42 | 7.5 | 0.00 | Oct 10, 2025 | cel-rust is a Common Expression Language interpreter written in Rust. Starting in version 0.10.0 and prior to version 0.11.4, parsing certain malformed CEL expressions can cause the parser to panic, terminating the process. When the crate is used to evaluate untrusted expressions (e.g., user-supplied input over an API), an attacker can send crafted input to trigger a denial of service (DoS). Version 0.11.4 fixes the issue. | ||
| CVE-2025-7507 | Med | 0.42 | 6.4 | 0.00 | Aug 15, 2025 | The elink – Embed Content plugin for WordPress is vulnerable to Malicious Redirect in all versions up to, and including, 1.1.0. This is due to the plugin not restricting URLS that can be supplied through the elink shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to supply an HTML file that can be leverged to redirect users to a malicious domain. | ||
| CVE-2025-53502 | Med | 0.42 | 6.5 | 0.00 | Jul 3, 2025 | Improper Input Validation vulnerability in Wikimedia Foundation Mediawiki - FeaturedFeeds Extension allows Cross-Site Scripting (XSS).This issue affects Mediawiki - FeaturedFeeds Extension: 1.39.X, 1.42.X, 1.43.X. | ||
