CVE-2026-88038[0]: | cookies is a Node.js library for reading and writing HTTP cookies, | used by Koa via ctx.cookies. In versions before 0.9.2 the library | validates the cookie name and value against character sets that | reject the semicolon separator, but the domain and path options are | checked only against a permissive RFC 7230 field-content matcher | that allows semicolons, and both are written into the Set-Cookie | header unescaped. An application that passes untrusted or request- | derived data into the domain or path option can therefore inject | additional cookie attributes, overriding SameSite, Secure, HttpOnly, | or Domain on the cookies the application issues. This is a Set- | Cookie attribute injection issue (CWE-74). The issue is fixed in | cookies 0.9.2, which validates domain and path against RFC 6265 | character sets. As a workaround, keep domain and path application- | set rather than derived from untrusted input. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
