Lifecycle Timeline
2DescriptionCVE.org
ColdFusion is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that could result in a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized write access. Exploitation of this issue does not require user interaction. Scope is changed.
AnalysisAI
OS command injection in Adobe ColdFusion 2023 and 2025 allows a low-privileged, network-authenticated attacker to bypass security controls and gain unauthorized write access to resources outside the application's normal permission boundary. The CVSS scope-change metric (S:C) confirms impact extends beyond the vulnerable component itself, meaning successful exploitation can affect the underlying operating system or adjacent system resources. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must possess a valid low-privileged ColdFusion application account (PR:L per CVSS vector) and network access to the ColdFusion server. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.7 score is well-supported by the vector components: AV:N (network-reachable without physical access), AC:L (no special race conditions or configuration quirks needed), PR:L (a low-privileged account suffices - any authenticated user), UI:N (fully automated exploitation once credentials are in hand), and S:C with I:H (high integrity impact across the broader system). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the update detailed in Adobe Security Bulletin APSB26-90, available at https://helpx.adobe.com/security/products/coldfusion/apsb26-90.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Adobe ColdFusion 2023 and 2025 instances in production and development environments; isolate any internet-facing deployments immediately. …
