UBUNTU-CVE-2026-33818

Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures...

CVE-2026-56860

CVE-2026-56860 describes a performance-related fix in path resolution for relative paths containing .. segments. The prior approach performed string conversions and buffer rewrites at each step, yielding quadratic time complexity and high memory allocations. The fix now operates on a byte buffer ...

CVE-2026-56862 Limit handshake messages we are willing to accept post-handshake in crypto/tls

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not. As a result, a malicious client can keep sending KeyUpdate messages to force the server to keep performing key derivation operations indefinitely...

EUVD-2026-58513

A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist attacker-controlled module content to a local Go module cache. This attack allows for a malicious GOPROXY to serve malicious module content that...

A malicious GOPROXY was previously capable of forging up to two sumdb tiles that allow for a requested module to bypass the GOSUMDB check and persist attacker-controlled module content to a local Go module cache. This attack allows for a malicious GOPROXY to serve malicious module content that...

CVE-2026-56853 Apply ReadHeaderTimeout when doing unencrypted HTTP/2 check in net/http

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface. ReadHeaderTimeout is unexpectedly not being applied when doing this...

CVE-2026-56858 Fix Javascript regexp context tracking in html/template

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS...

EUVD-2026-58514

A malicious GOSUMDB was capable of serving arbitrary module content not contained within the transparency log. This attack allows for a coordinating GOPROXY and GOSUMDB to serve a client malicious module content that cannot be detected by evaluating the transparency log. In order to determine if...
