CVE-2025-46653
Last modified
CVE-2025-46653 is a low-severity vulnerability rated 3.1/10 on the CVSS scale. Formidable (aka node-formidable) 2.1.0 through 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.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
