Last modified

CVE-2025-8154 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In Webhook API invocations, the component accepts user-supplied input for HTTP request headers without sufficient validation or sanitization, allowing these headers to be injected into HTTP responses. By exploiting this vulnerability, a malicious actor can inject or overwrite arbitrary HTTP response headers. This can lead to various adverse effects, including the manipulation of browser caching, alteration of security-related headers, and the injection of sensitive information such as cookie values, potentially enabling session hijacking or other malicious activities.. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
