CVE-2026-66753 tiny-http 0.12.0 HTTP Response Splitting via Header Injection

tiny-http through 0.12.0 contains an HTTP header injection vulnerability that allows attackers to inject carriage return 0x0D and line feed 0x0A bytes into HTTP header values on both request and response sides due to insufficient validation in header parsing and serialization. Attackers can explo...

TBK DVR4104/DVR4216 Devices - Authentication Bypass

TBK DVR4104 and DVR4216 devices, as well as Novo, CeNova, QSee, Pulnix, XVR 5 in 1, Securus, Night OWL, DVR Login, HVR Login, and MDVR Login, which run re-branded versions of the original TBK DVR4104 and DVR4216 series, allow remote attackers to bypass authentication via a "Cookie: uid=admin"...

undici: undici: Weakening of cookie SameSite policy due to incorrect parsing of Set-Cookie header

A flaw was found in undici. When undici processes Set-Cookie headers, it incorrectly interprets the SameSite attribute, accepting partial matches instead of exact ones. This allows a malicious server to downgrade a cookie's SameSite policy to a less secure setting, potentially leading to unintend...

EUVD-2026-43639

In Eclipse Vert.x versions up to and including 4.5.29 4.x branch and 5.1.4 5.x branch, DefaultRedirectHandler vertx-core propagates all request headers as-is across cross-origin HTTP 30x redirects. Only Content-Length is stripped; no origin comparison scheme, host, port is performed before copyin...

CVE-2026-15075

CVE-2026-15075 affects Eclipse Vert.x up to 4.5.29 (4.x) and 5.1.4 (5.x). The DefaultRedirectHandler in vertx-core forwards all request headers across cross-origin HTTP 30x redirects, stripping only Content-Length. No origin check is performed before copying headers to the redirect target. This a...

CVE-2026-15076

In versions up to and including 4.5.29 4.x branch and 5.1.4 5.x branch, the WebClientSession component of Eclipse Vert.x Web Client does not validate that the Domain attribute of a Set-Cookie response header matches the originating server's domain, in violation of RFC 6265 section 5.3. An attacke...

PYSEC-2026-2647 Kiota abstractions RedirectHandler leaks Cookie/Proxy-Authorization headers on cross-host redirect

Summary The RedirectHandler middleware in microsoft/kiota-java com.microsoft.kiota:microsoft-kiota-http-okHttp v1.9.0 and other Kiota libraries fails to strip sensitive HTTP headers when following 3xx redirects to a different host or scheme. This vulnerability is present in the RedirectHandlers...
