SCA: security update for form-data (GHSA-hmw2-7cc7-3qxx)

high Tenable Self-Hosted Container Security Plugin ID 443190

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - form-data is a library for creating readable multipart/form-data streams. In versions through 4.0.5, the
 `field` argument to `FormData#append` and the `filename` option are concatenated verbatim into the
 `Content-Disposition` header without escaping carriage return (CR), line feed (LF), or double-quote (")
 characters. An application that passes attacker-controlled data as a field name or filename (for example,
 an API gateway that turns JSON object keys into multipart field names) allows the attacker to terminate
 the header line and inject additional headers, or to smuggle entire additional multipart parts, into the
 request the application forwards to a backend. This can let the attacker add or override form fields (e.g.
 set `is_admin=true`) seen by the downstream parser. This is an instance of CWE-93 (CRLF injection). The
 fix escapes CR, LF, and `"` as `%0D`, `%0A`, and `%22` in field names and filenames, matching the
 serialization browsers use per the WHATWG HTML multipart/form-data encoding algorithm. Exploitation
 requires the consuming application to use untrusted input as a field name or filename; applications that
 use only fixed/trusted field names are not affected. Fixed in 2.5.6, 3.0.5, and 4.0.6. (CVE-2026-12143)

Solution

Update the form-data library and its related packages to version 2.5.6 or later.
