What it is about

ColdFusion ist ein Applikationsserver sowie Framework zur Erstellung von Web basierten Applikationen. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Adobe ColdFusion ausnutzen, um beliebigen Code auszuführen, erweiterte Berechtigungen zu erlangen, Sicherheitsmaßnahmen zu umgehen, Cross-Site-Scripting-Angriffe durchzuführen, Daten zu manipulieren oder vertrauliche Informationen offenzulegen.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

  • beliebigen Code auszuführen
  • erweiterte Berechtigungen zu erlangen
  • Sicherheitsmaßnahmen zu umgehen
  • Cross-Site-Scripting-Angriffe durchzuführen
  • Daten zu manipulieren oder vertrauliche Informationen offenzulegen

Am I affected?

Affected according to the BSI:

  • Adobe ColdFusion ColdFusion 2025 <Update 10
  • Adobe ColdFusion ColdFusion 2023 <Update 21

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Adobe ColdFusion ColdFusion 2025 Update 10
  • Adobe ColdFusion ColdFusion 2023 Update 21

Is the vulnerability already being exploited?

  • CVE-2026-48282: exploited in the wild according to CISA, in the catalogue since 07.07.2026.
