CWE-138 vulnerabilities

CVE-2026-62971 is a vulnerability in the OWASP core rule set (CRS) affecting versions prior to 3.3.10, 4.25.1, and 4.28.0. The issue involves improper neutralization of special elements in XML request bodies, where CRS rules inspect only element text nodes but not XML attribute values. This allows attackers to bypass detection by placing malicious payloads inside XML attributes. The vulnerability affects approximately 159 rules across nine rule files and applies to all paranoia levels except the 944 (Java) family, which is unaffected. The issue has been patched in the specified fixed versions.

CVE-2026-55841 is a vulnerability in Graylog2-server affecting the FortiGate key-value syslog parser. It mishandles field-like text inside quoted values, allowing crafted syslog messages to manipulate or remove security-log fields. This can enable an unauthenticated network sender to obscure malicious activity by evading logging. The issue is fixed in Graylog Server versions 6.3.12, 7.0.7, 7.1.2, and Graylog Forwarder version 7.3.

Improper neutralization of special elements used in a command ('command injection') in M365 Copilot allows an unauthorized attacker to disclose information over a network.

Improper neutralization of special elements in .NET allows an unauthorized attacker to perform spoofing over a network.

tarteaucitron.js is a compliant and accessible cookie banner. Prior to version 1.22.0, a vulnerability was identified in tarteaucitron.js where document.currentScript was accessed without verifying that it referenced an actual <script> element. If an attacker injected an HTML element, it could clobber the document.currentScript property. This causes the script to resolve incorrectly to an element instead of the <script> tag, leading to unexpected behavior or failure to load the script path correctly. This issue arises because in some browser environments, named DOM elements become properties on the global document object. An attacker with control over the HTML could exploit this to change the CDN domain of tarteaucitron. This issue has been patched in version 1.22.0.
