Affected: CleanStart: langfuse-worker

Package langfuse-worker version 3.216.0-r1 fixes 29 vulnerabilities: ghsa-frvp-7c67-39w9, ghsa-p63j-vcc4-9vmv, ghsa-55q2-fjhq-7xh7, ghsa-c2j3-45gr-mqc4, CVE-2026-69192...

undici's setCookie function does not fully sanitize cookie attributes. In undici before 6.28.0, from 7.0.0 up to before 7.29.0, and from 8.0.0 up to before 8.9.0, a domain value is not checked for semicolons and entries in the unparsed array are not sanitized, so attacker-influenced input can inject additional cookie attributes. For example, a domain value containing a semicolon can append attributes such as SameSite, and an unparsed entry can inject attributes such as HttpOnly, without the caller setting them. Applications that pass user-controlled input to these fields, such as multi-tenant or reverse-proxy servers that scope session cookies to a tenant-supplied domain, can have SameSite CSRF protections bypassed, or the Secure, HttpOnly, and SameSite attributes forced, stripped, or overridden. The issue is fixed in undici 6.28.0, 7.29.0, and 8.9.0.

Affected: npm: undici

## Impact

The `setCookie` function has two attribute injection paths. `validateCookieDomain` does not reject semicolons (`validateCookiePath` already does at 0x3B), so a `domain` value like `example.com; SameSite=None` lands verbatim as `Domain=example.com; SameSite=None`. The `unparsed` array's loop only checks each entry contains `=` and does not sanitize values, so an entry like `X-Custom=val; HttpOnly` lands unchanged, injecting `HttpOnly` without the caller setting `cookie.httpOnly = true`.

Applications that pass user-controlled input to these fields, typically multi-tenant or reverse-proxy servers that scope session cookies to a tenant-supplied domain, can have SameSite CSRF protections bypassed, `Secure` or `HttpOnly` forced or stripped, or the intended SameSite tier overridden.

## Patches

Patched in undici v6.28.0, v7.29.0, and v8.9.0.

## Workarounds

- Sanitize `domain` values against the RFC 1034 letter-digit-hyphen set before passing to `setCookie`. - Do not pass user-controlled data to the `unparsed` field.
