CVE-2025-31125: Vite has a `server.fs.deny` bypassed for `inline` and `raw` with `?import` query

HighCVSS 7.5 · v3.1KEVWeaponized Fix available

Noroxi assessment

Priority: Now (action score 82/100)

  • CISA has confirmed exploitation in the wild (Jan 22, 2026). Remediation deadline for US federal agencies: Feb 12, 2026.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 74.9% (FIRST EPSS); higher than 99.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: vitejs vite 6.2.4.
  • Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 7.5.

Patch today or shut off access. Upgrade to vitejs vite 6.2.4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

Vite is a frontend tooling framework for javascript. Vite exposes content of non-allowed files using ?inline&import or ?raw?import. Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected. This vulnerability is fixed in 6.2.4, 6.1.3, 6.0.13, 5.4.16, and 4.5.11.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jan 22, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Feb 12, 2026.
