User-context code execution via reflected script injection
Published Jun 30, 2026 · Updated Aug 27, 2026
Reflected XSS in Adobe ColdFusion 2025.9 and 2023.20 and earlier allows attackers to execute code in a user's context. Adobe has not disclosed the affected endpoint, input parameter, or the output-encoding operation that reflects attacker-controlled script content. Exploitation requires an unauthenticated attacker to induce the victim to open a malicious link; execution then occurs in that victim's context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=20
- Affected versionversion=0 <=9
