# CVE-2026-77526: FacturaScripts: Path traversal in UploadedFile::move() via getClientOriginalName() — arbitrary file write outside MyFiles/ leading to   RCE

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes facturascripts/facturascripts (Composer (PHP)) >= 2025, <= 2026.2, fixed in 2026.3 . Check your lockfile, including transitive dependencies.
