What happened

On 27 October 2026, Adobe published two bulletins.

APSB26-162, Adobe Campaign Classic. Eight critical flaws in Campaign Classic v7 7.4.4 build 9402 and earlier, on Windows and Linux, fixed in build 9403 (Adobe APSB26-162):

CVE-2026-104350Reflected XSSPrivilege escalation9.3None, but a victim must open a link
CVE-2026-104354SQL injectionSecurity feature bypass9.1High-privileged user
CVE-2026-105779SQL injectionSecurity feature bypass9.1Low-privileged user

The CVE records describe several of these more severely than the bulletin. CVE-2026-105781 is scored 10.0 there, and its description says an attacker can run arbitrary SQL without user interaction. CVE-2026-105489 and CVE-2026-104354 are described as leading to code execution (CVE-2026-105781; CVE-2026-105489; CVE-2026-104354). The low-privileged code execution bugs need no user interaction, so any operator account, or a stolen one, is enough.

APSB26-182, Adobe Connect. CVE-2026-48360 is a code injection flaw in the Connect desktop app and Android app, CVSS 9.6. A victim has to open a malicious link or page. Affected: Windows 2026.8.51 and below, macOS Apple silicon 2026.08.45 and below, macOS Intel 2026.01.39 and below, Android 4.4 and earlier (Adobe APSB26-182).

Adobe says it is not aware of exploits in the wild for any of these issues and rates both bulletins priority 2 (Adobe APSB26-162; Adobe APSB26-182). None of the CVEs was in CISA’s KEV catalog as of 30 October (CISA KEV).

Am I affected?

Campaign Classic: any v7 instance at 7.4.4 build 9402 or earlier. The bulletin covers Windows and Linux servers. On the application server, the server build is printed by:

bash
nlserver pdump

You can also see the build in the client console’s About box. If Adobe hosts your Campaign instance, ask Adobe support whether it is on build 9403.

Exposure is highest where the Campaign web server is reachable from the internet, for example for tracking, landing pages or web forms, and where many operator accounts exist.

Adobe Connect: check the app version on Windows, macOS and Android devices against the fixed builds. Only the desktop and Android apps are listed as affected.

What to do now

  1. Upgrade every Campaign Classic v7 server to 7.4.4 build 9403, starting with instances whose web interfaces are reachable from outside.
  2. Until upgraded, limit access. Restrict who can reach the Campaign console and server interfaces to known networks, and remove or disable operator accounts nobody uses. Most of these bugs need only a low-privileged operator login.
  3. Review operator activity for logins from unfamiliar addresses and new or changed workflows and JavaScript activities since your last upgrade. Adobe has not published indicators, so this is about spotting misuse of operator accounts.
  4. Push Adobe Connect 2026.9.61 (Windows), 2026.10.66 (Apple silicon), 2026.10.170 (Intel Macs) and 4.5 (Android) through your software distribution tool. Adobe gives no workaround for either bulletin.
