Adobe Campaign Classic (ACC) is affected by an Incorrect Authorization vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.
Security readout for executives and security teams
Plain-English summary
Adobe Campaign Classic has a critical authorization flaw that may let an unauthenticated remote attacker run code with the affected application user’s privileges. No user action is required. Successful compromise could expose data, alter systems, or disrupt service, although the supplied sources do not establish active exploitation.
Executive priority
Treat as an immediate remediation priority for any potentially affected or externally reachable deployment. The maximum CVSS score and unauthenticated code-execution impact justify urgent action, while the absence of confirmed active exploitation should not be interpreted as evidence of safety.
Technical view
CVE-2026-48449 is a CWE-863 incorrect authorization vulnerability with CVSS 3.1 score 10.0. The supplied vector indicates network access, low complexity, no privileges, no user interaction, changed scope, and high confidentiality, integrity, and availability impact. The affected-version data identifies Adobe Campaign Classic through 7.4.3 build 9398, but should be confirmed against Adobe’s advisory.
Likely exposure
Exposure is most likely where Adobe Campaign Classic installations within the stated affected range are reachable by untrusted networks. Actual risk depends on deployed build, accessibility, and application-user privileges. The bundle’s default status is unaffected outside the listed range, but asset owners should verify version applicability with Adobe.
Exploitation context
The supplied CVSS vector supports unauthenticated remote exploitation without user interaction and potential arbitrary code execution. However, the CVE is not listed as KEV in the bundle, and no supplied source confirms active exploitation, public exploit availability, or observed attacks.
Researcher notes
The supplied record describes incorrect authorization leading to code execution in the current user context and changed scope. It does not provide the vulnerable component, request path, root cause, indicators of compromise, or explicit fixed build. Avoid inferring those details; consult APSB26-114 for authoritative applicability and remediation information.
Mitigation direction
Review Adobe advisory APSB26-114 and apply its specified security update or mitigation promptly.
Restrict Campaign Classic access to trusted networks while remediation is pending.
Reduce the application service account’s privileges where operationally safe.
Monitor Campaign Classic systems for unexpected processes, account activity, configuration changes, and outbound connections.
Validation and detection
Inventory all Adobe Campaign Classic deployments and record exact versions and build numbers.
Compare each deployment with Adobe advisory APSB26-114 applicability and remediation guidance.
Identify internet-facing or otherwise untrusted network paths to affected installations.
After remediation, confirm the installed build and verify access restrictions remain effective.
Review relevant application, operating-system, authentication, and network logs for suspicious activity.

CWE-863: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Incorrect Authorization
Incorrect Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
