Three Critical Vulnerabilities in Adobe Campaign Classic Allow Arbitrary Code Execution

Adobe has disclosed three severe vulnerabilities in Adobe Campaign Classic that could permit attackers to execute arbitrary code on affected systems. The issues affect both Windows and Linux versions and include two OS command injection flaws along with one server-side request forgery vulnerability. Each vulnerability received the maximum CVSSv3.1 base score of 10.0 and is rated Critical. Adobe released fixes in version 7.4.4 build 9401, which must be applied to on-premises components in both pure on-premises and hybrid environments. Although no active exploitation has been observed, Adobe assigned the highest priority level and recommends applying the update within 72 hours.

Adobe Releases Third Emergency Patch for Campaign Classic in Two Weeks, Fixing Critical RCE Vulnerabilities

Adobe has issued another urgent security update for Adobe Campaign Classic after discovering multiple critical vulnerabilities that affect the previous patches released on July 29 and August 3. The new advisory, published on August 11, 2026, addresses three CVEs rated Critical, including two remote code execution flaws with CVSSv3.1 base scores of 10.0. These authorization bypass issues allow unauthenticated attackers to execute arbitrary code remotely. The affected versions include 7.4.3 build 9398 and build 9399, which were themselves emergency fixes issued only days earlier. Adobe urges all customers to apply the latest update immediately due to the high risk of exploitation. This marks the third high-severity patch for the product within a two-week period.

Prepare for Summer Vacation: Patch Tuesday Overlaps with Obon Holiday Week Raises Risks

As August approaches and organizations enter summer vacation season, many will face a challenging overlap between Microsoft's Patch Tuesday and Japan's Obon holiday week in 2026. System administrators and security teams are often unavailable during extended breaks, leading to slower detection, reporting, and remediation of threats. Ransomware campaigns frequently target periods such as evenings, weekends, and consecutive holidays when response times are delayed. Experts recommend completing software updates on servers, network devices, and endpoints before departure to close known vulnerabilities. Security product definition files should be refreshed, unused systems powered down after risk assessment, and basic controls verified in advance. The advisory from Security NEXT highlights that dispersed vacation schedules in some organizations still leave concentrated risk windows for others.
