# CVE-2026-48313: ColdFusion | Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22)

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (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 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 3.0% , percentile 87: FIRST’s model estimates a 3.0% chance of exploitation activity in the next 30 days, higher than 87% 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.
- Editorial verdict: Check exposure. ColdFusion CVE-2026-48282: Exploited RDS Path Traversal — Every ColdFusion 2023/2025 server should already be on the June updates; if RDS was enabled without authentication and reachable, assume the box may be compromised and hunt.
