    Formidable relies on hexoid to prevent guessing of filenames for untrusted executable content

    CVE-2025-46653 · GHSA-75v8-2h7p-7m2m

    Affected
    • npm formidable >= 3.1.1-canary.20211030, < 3.5.3; >= 2.1.0, < 2.1.3
    Fixed in
    3.5.32.1.3· Vendor fix available
    Issue
    Formidable (aka node-formidable) 2.x before 2.1.3 and 3.x before 3.5.3 relies on hexoid to prevent guessing of filenames for untrusted executable content; however, hexoid is documented as not "cryptographically secure." (Also, there is a scenario in which only the last two characters of a hexoid string need to be guessed, but this is not often relevant.) NOTE: this does not imply that, in a typical use case, attackers will be able to exploit any hexoid behavior to upload and execute their own content.

    Recommended action: Upgrade to 3.5.3 or 2.1.3 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
