Executive Summary
In August 2026, Adobe disclosed a critical vulnerability (CVE-2026-48449) in its Campaign Classic platform, rated with a CVSS score of 10.0. This flaw, stemming from incorrect authorization, allows attackers to execute arbitrary code without user interaction, potentially compromising systems running affected versions. Additionally, a high-severity SQL injection vulnerability (CVE-2026-48448) was identified, enabling unauthorized file reads. Adobe has released updates to address these issues and recommends immediate application to mitigate risks.
The disclosure underscores the persistent threat posed by authorization and input validation vulnerabilities in enterprise software. Organizations are urged to prioritize patch management and conduct regular security assessments to prevent exploitation of such critical flaws.
Why This Matters Now
The recent discovery of critical vulnerabilities in Adobe Campaign Classic highlights the ongoing risks associated with software authorization flaws. Immediate patching is essential to prevent potential exploitation and safeguard sensitive data.
Attack Path Analysis
An attacker exploited a critical vulnerability in Adobe Campaign Classic to execute arbitrary code without user interaction. They escalated privileges by exploiting a Server-Side Request Forgery (SSRF) vulnerability, allowing unauthorized access to internal resources. The attacker moved laterally within the network by leveraging compromised credentials and exploiting misconfigurations. They established command and control by deploying malware that communicated with external servers. Sensitive data was exfiltrated through encrypted channels to evade detection. The attack culminated in significant operational disruption and potential data loss.
