CVE-2026-39963: CWE-565: Reliance on Cookies without Validation and Integrity Checking in s9y SerendipityCVE-2026-39963 0 Serendipity versions prior to 2. 6. 0 contain a vulnerability where the function serendipity_setCookie() uses the HTTP Host header without validation when setting cookies. This allows an attacker who can manipulate the Host header during login to cause authentication cookies to be scoped to an attacker-controlled domain. The vulnerability enables session fixation, token leakage, and potential privilege escalation if an administrator logs in under a manipulated Host header. The issue is fixed in version 2. 6. 0.
