   Published 2026-10-28

   High·CVSS 8.2 EPSS 0.32%

   decode-uri-component provides a more robust alternative to decodeURIComponent. Prior to 0.5.1, decodeUriComponent in index.js falls back to customDecodeURIComponent after native decoding throws, and the fallback collects every distinct percent-encoded run before performing a full...

4. CVE-2026-110879 jackson-databind: PolymorphicTypeValidator bypass via generic type arguments and array element types allows arbitrary class instantiation (incomplete fix for CVE-2026-54512)

   Published 2026-10-28

   Critical·CVSS 9.8 EPSS 1.2%

   jackson-databind validates the outer class of a class-name type ID but accepts attacker-selected classes inside its generic arguments, even when those classes violate the declared type or would be rejected as direct type IDs. This bypasses the generic-argument validation added fo...

5. CVE-2026-116591 compress zstd: Panic on two-block frames

   Published 2026-10-26

   High·CVSS 8.7 EPSS 0.33%

   compress provides various compression algorithms. Prior to 1.20.2, the zstd DecodeAll and streaming decoder paths can panic when a crafted two-block frame reaches huff0.ReadTable with an FSE normalized count of 32768 that readNCount stores in int16 as -32768. The wrapped count al...

6. CVE-2026-111943 Distrust compromised intermediate certificates in crypto/x509

   Published 2026-10-21

   Medium·CVSS 6.8 EPSS 0.40%

10. CVE-2026-97032 HTTP/2 server crash due to HPACK encoder race in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.68%

    HTTP/2 servers could end up crashing due to inadvertently modifying its HPACK encoder concurrently. This happens because the server modifies the HPACK encoder from two goroutines without synchronization: one uses the encoder to encode a HEADERS frame as part of a response sent to...

11. CVE-2026-94439 HTTP/1 server connection desynchronization after 2xx CONNECT response in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.53%

    When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tun...

12. CVE-2026-78669 Excessive CPU consumption from repeated initial window changes in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.85%

    A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGS_INITIAL_WINDOW_SIZE values.

13. CVE-2026-78667 Lack of limit on size of parsed Range headers in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.66%

    When parsing a Range header containing a large number of small ranges, FileServer(FS), ServeContent, and ServeFile(FS) can consume an excessive amount of CPU.

14. CVE-2026-78663 Double flow control refund on HTTP/2 server streams in net/http

    Published 2026-10-08

    Critical·CVSS 9.1 EPSS 0.86%

    The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream (refunding data for any sent-but-unread portion of the stream), and again when a request handler reads the buffered data. A malicious client can exploit this to...

15. CVE-2026-78660 HTTP/2 transport accepts malformed framing-related headers in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.54%

    Historically, we have been rather lax about malformed framing-related headers in our HTTP/2 implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client...

16. CVE-2026-97031 Reject malformed ECH outer extension references in crypto/tls

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.72%

    Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory ampli...

17. CVE-2026-94440 Memory limit bypass when parsing MIME headers in net/textproto, mime/multipart

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.71%

    Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when the remaining limit at the start of a part is less than 400 bytes.

18. CVE-2026-78659 HTTP/2 server memory exhaustion due to Trailer headers in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.87%

    When "Trailer" headers are sent by a client, the HTTP server internally uses the header values to populate the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs memory overhead. For HTTP/2 servers, a malicious client can exploit...

19. CVE-2026-56866 HTTP/1 client connection desynchronization after CONNECT rejection in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.60%

    When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connecti...

20. CVE-2026-97030 Recognize yield as regexp preceder keyword in html/template

    Published 2026-10-08

    Medium·CVSS 6.1 EPSS 0.29%

    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-keyword uses are not escaped.

21. CVE-2026-94448 Reset context tracking on consecutive template expressions in html/template

    Published 2026-10-08

    Medium·CVSS 6.1 EPSS 0.29%

    When a JavaScript template literal contains consecutive expressions, the context tracking state was not properly reset upon entering a new expression. We now ensure that template-literal expression entries correctly reset context variables so all subsequent regular expression lit...

22. CVE-2026-71888 CMS AuthenticatedData exposes attacker-inserted authAttrs when digestAlgorithm is absent
