Summary

CVE-2026-48381 is a critical SQL injection vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command) in Adobe Campaign Classic (ACC) v7. Successful exploitation can enable an attacker to execute arbitrary code in the context of the current user. The flaw does not require user interaction or authentication, and Adobe rates it 9.0 (Critical) on the CVSS v3.1 scale.

Technical details

  • Root cause: Adobe Campaign Classic fails to properly neutralize special characters in SQL statements, allowing crafted input to be interpreted as SQL commands rather than data.
  • Trigger conditions: Exploitation does not require user interaction, but success depends on specific, unspecified conditions being met on the target environment (reflected in the High attack complexity rating).
  • Attack vector: Network — the vulnerability can be exploited remotely over the network without prior authentication (Privileges Required: None).
  • Impact: A successful attack results in arbitrary SQL injection that can be leveraged for arbitrary code execution in the context of the current user, with high impact to confidentiality, integrity, and availability. The CVSS vector’s changed scope (S:C) indicates the vulnerability can affect resources beyond the vulnerable component itself.

Affected software

  • Adobe Campaign Classic v7 — versions up to and including build 9399 (Windows and Linux)

Severity

  • CVSS v3.1 Base Score: 9.0 (Critical)
  • Vector string: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade Adobe Campaign Classic v7 to build 9400 or later, as released in Adobe’s security bulletin (APSB26-123). This is the officially patched version and should be applied as soon as possible given the critical severity and network attack vector.
  • If immediate patching is not possible:
    • Restrict network access to Adobe Campaign Classic management and application interfaces to trusted internal networks or VPN only, minimizing internet exposure.
    • Monitor application and database logs for anomalous or malformed SQL query patterns indicative of injection attempts.
    • Apply web application firewall (WAF) rules to detect and block common SQL injection payloads targeting ACC endpoints as a temporary compensating control until the patch is applied.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
