CVSS 9.4 Critical EPSS 3.9% · p90

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 3.9%, percentile 90: FIRST’s model estimates a 3.9% chance of exploitation activity in the next 30 days, higher than 90% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
  • Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
  • Only applies if your dependency tree includes dedoc/scramble (Composer (PHP)) >= 0.13.2, <= 0.13.21, fixed in 0.13.22. Check your lockfile, including transitive dependencies.

What it is

Scramble generates API documentation for Laravel project. From 0.13.2 to before 0.13.22, when documentation endpoints are publicly accessible and validation rules reference user-controlled input, request supplied data may be evaluated during documentation generation, leading to execution of arbitrary PHP code in the application context. This vulnerability is fixed in 0.13.22.

From the GitHub advisory

Impact

A remote code execution (RCE) vulnerability affects versions 0.13.2 through 0.13.21.
