A vulnerability in the Go standard library's net/http package allows for HTTP/1 server connection desynchronization after a 2xx CONNECT response. This issue can lead to potential request smuggling in certain scenarios. The vulnerability arises when an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, causing the server to improperly continu [truncated]
A vulnerability in the Go standard library's handling of Range headers can lead to excessive CPU consumption when parsing large numbers of small ranges. This issue affects the FileServer, ServeContent, and ServeFile functions in the net/http package. The vulnerability is identified as CVE-2026-78667 and is tracked by the CVE Program. The issue arises from the lack of a limit on the size of parsed Range he [truncated]
A vulnerability in the Go standard library's net/http package can lead to cross-user response poisoning in reverse proxies that forward CONNECT requests through a shared Transport. This occurs when http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, and the server rejects the CONNECT request with a non-2xx keep-alive response. The connection may be returned to the idle pool in a [truncated]
A vulnerability in the Go standard library's `os` package allows an attacker to create a directory outside the intended root directory on Windows when using `Root.Mkdir` or `Root.MkdirAll` with a junction pointing to an empty location. This issue arises when the target of these operations is a junction pointing to an empty location, enabling the creation of a directory at the junction target even if it's [truncated]
The Go standard library's html/template package did not correctly escape the 'yield' keyword, potentially allowing for template injection attacks. This has been addressed in versions 1.26.9 and 1.27.2. A trusted template author may have previously written a valid template wherein the use of the 'yield' keyword would not be correctly escaped. We now ensure that valid keyword uses are escaped and non-keywor [truncated]
This PatchSiren debrief is based on the supplied source corpus for CVE-2026-94448, which involves a context tracking issue in the html/template package of the Go standard library. The issue arises when consecutive expressions are present in a JavaScript template literal, leading to improper context tracking state reset. This could potentially impact the accurate recognition and escaping of subsequent regu [truncated]

The NVD entry is currently Awaiting Analysis. This CVE-2026-56862 vulnerability involves potential issues with handshake messages, such as KeyUpdate. A malicious client could potentially force a server to perform indefinite key derivation operat [truncated]
The CVE-2026-56859 vulnerability affects the DecodeElement function in the Go programming language, potentially leading to stack exhaustion and denial-of-service (DoS) conditions. This HIGH-severity vulnerability, with a CVSS score of 7.5, requires immediate attention. Affected systems and components should be identified, and patches or updates provided by the Go vendor should be reviewed and applied. Com [truncated]
A vulnerability was found in an unknown product, potentially allowing a passive network observer to de-anonymize handshakes that used Encrypted Client Hello due to the disclosure of pre-shared key identities in the unencrypted client hello. The vulnerability affects systems utilizing Encrypted Client Hello handshakes. Security teams should review the vulnerability details and assess the potential impact o [truncated]
A vulnerability in the Go standard library's os.Root component improperly handles symbolic links, potentially allowing unauthorized file access. This issue affects various versions of the Go programming language. The vulnerability arises when the final path component of a path is a symbolic link and the path ends in /. To address this, developers should assess their exposure, verify affected versions, and [truncated]
