CVE-2026-48282: Adobe ColdFusion Path Traversal Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run Adobe ColdFusion. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-07-07, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-07-10; treat that as the outer limit, not the target.
• EPSS 42.4%, percentile 99: FIRST’s model estimates a 42.4% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). 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.
