CVE-2026-56851

A flaw was found in golang.org/x/text. An attacker can cause a Denial of Service (DoS) by submitting specially crafted input to an application utilizing the Nickname profile. When transforming this input into an undersized destination buffer, an out-of-bounds slice indexing error occurs, causing the application to panic and crash.

7.5 (High)

Threats

Impact Important

CVE-2026-93450

A flaw was found in the `go-openapi/swag` library's `jsonutils` component. This vulnerability, caused by uncontrolled recursion during ordered JSON (JavaScript Object Notation) parsing and serialization, allows remote unauthenticated attackers to submit deeply nested JSON documents. This can lead to a stack overflow, terminating the process and causing a Denial of Service (DoS) for services that accept OpenAPI specifications.

7.5 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-770 - Allocation of Resources Without Limits or Throttling

Affected products

Fixed 3 products, the same list as for CVE-2026-56851

Threats

Impact Important

CVE-2026-102422

A flaw was found in shell-quote. This vulnerability allows an attacker to achieve arbitrary command execution by supplying crafted input containing line break characters after a comment marker. When input is quoted, the comment marker comments out subsequent quotes until a newline is encountered, causing any following text on new lines to be executed as shell commands by the underlying system.

8.1 (High)


                
                  CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Affected products

Fixed 3 products, the same list as for CVE-2026-56851

CVE-2026-102422 (GCVE-0-2026-102422)

Vulnerability from cvelistv5 – Published: 2026-09-29 03:47 – Updated: 2026-09-30 15:18

Title

shell-quote `quote()` command injection via a line terminator in a token after a `{ comment }` token

Summary

shell-quote's `quote()` function emits a `{ comment }` token as `#` followed by its text, which comments out the rest of the shell line, including the opening quote of any later string token. A line terminator (\n, \r, U+2028, U+2029) in that later string therefore ends the comment, and the rest of the string is parsed as shell input: `quote(['echo', 'ok', { comment: 'x' }, 'a\nid;#'])` runs `id` in sh, bash, dash, ksh and zsh. `parse()` emits a comment token for a `#` in the middle of a word (for example `http://example.com/#frag`), so callers that combine `parse()` output with another untrusted string, such as `quote(parse(untrustedCommand).concat(untrustedArg))`, are affected. The fix for CVE-2026-9277 rejected line terminators in the comment's own text, but not in the tokens after it. Fixed in 1.11.0: `quote()` throws a `TypeError` when a string after a `{ comment }` token contains a line terminator.

Title

go-openapi/swag jsonutils before 0.27.1 Uncontrolled Recursion in Ordered JSON Marshal and Unmarshal

Summary

go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests.
