CVE-2026-47889 Aug 27, 06:17 HIGH This Week

WebFlux applications in Spring Framework running on the Jetty 12 Core reactive adapter omit the SameSite cookie attribute from serialized response cookies, exposing session and authentication cookies to cross-site request contexts. Affected versions span Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8, covering a substantial footprint of reactive Java deployments on Jetty 12. The vulnerability carries a vendor CVSS of 7.5 with C:H reflecting potential session-token disclosure; no public exploit code or active exploitation (CISA KEV) has been identified, and EPSS places exploitation probability at 0.14% (4th percentile).

CVE-2026-55688 Jul 01, 19:40 Maven MEDIUM PATCH GHSA This Month

Cookie tossing in AsyncHttpClient (AHC) library allows a malicious HTTP server to plant cookies scoped to an unrelated trusted domain, affecting versions 2.0.0-2.15.x and 3.0.0.Beta1-3.0.10. ThreadSafeCookieStore accepts and stores a cookie's Domain attribute value without verifying that the responding host is authorised to set cookies for that domain, so any server the client contacts can inject a cookie that AHC will automatically forward to the targeted domain on subsequent requests. Java applications sharing a single AHC instance - and therefore its default shared CookieStore - across calls to both attacker-influenced and trusted hosts are the primary attack surface; no public exploit has been identified at time of analysis, and vendor-released fixes are available in 2.16.0 and 3.0.11.
