| CVE-2026-39830 | Cri | 9.1 | < 18.6.8-r17 | 18.6.8-r17 | May 22, 2026 | A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now | |
| CVE-2026-39829 | Hig | 7.5 | < 18.6.8-r17 | 18.6.8-r17 | May 22, 2026 | The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification.

| CVE-2026-39827 | Med | 6.5 | < 18.6.8-r17 | 18.6.8-r17 | May 22, 2026 | An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state | |

If a crafted image provides an `/etc/passwd` file mapping this large numeric string to root, the con | |
| CVE-2026-41506 | Med | 4.7 | < 18.6.8-r13 | 18.6.8-r13 | May 8, 2026 | go-git is an extensible git implementation library written in pure Go. Prior to versions 5.18.0 and 6.0.0-alpha.2, go-git may leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations. This issue has been patched in versions 5.18.0 | |
| CVE-2026-42501 | Hig | 7.5 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | A malicious module proxy can exploit a flaw in the go command's validation of module checksums to bypass checksum database validation.

| CVE-2026-42499 | Hig | 7.5 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322. | |
| CVE-2026-39836 | Hig | 7.5 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0). | |
| CVE-2026-39826 | Med | 6.1 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | If a trusted template author were to write a tag containing an empty 'type' attribute or a 'type' attribute with an ASCII whitespace, the execution of the template would incorrectly escape any data passed into the block. | |
| CVE-2026-39825 | Med | 5.3 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.Pa | |
| CVE-2026-39823 | Med | 6.1 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a tag's attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the attribute, the escaper would fail to similarly escape it, le | |
| CVE-2026-39820 | Hig | 7.5 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations. | |
| CVE-2026-39819 | Med | 5.3 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | The "go bug" command writes to two files with predictable names in the system temporary directory (for example, "/tmp"). An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink. | |
| CVE-2026-39817 | Med | 5.9 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | The "go tool pack" subcommand (usually used only by the compiler as an internal tool with known-good inputs) does not sanitize output filenames. Extracting a malicious archive file with the "pack" subcommand can write files to arbitrary locations on the filesystem. | |
| CVE-2026-33814 | Hig | 7.5 | < 18.6.8-r17 | 18.6.8-r17 | May 7, 2026 | When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0. | |
| CVE-2026-33811 | Hig | 7.5 | < 18.6.8-r14 | 18.6.8-r14 | May 7, 2026 | When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C memory and a crash. |
