- No exploitation in the wild and no public exploit is recorded for the CVEs named.
NCSC-NL published an advisory summarizing Adobe's security update for Adobe Connect (fixed in version 12.12) and the Adobe Connect Android Mobile App (fixed in version 4.5), addressing nine vulnerabilities spanning SQL injection, stored and reflected cross-site scripting, insufficient input validation, path traversal, and improper certificate validation. Seven of the nine flaws are rated critical by Adobe, with six scoring 9.3 or higher on CVSS v3. The most severe, CVE-2026-75682 (CVSS 9.9), is a SQL injection flaw allowing a low-privileged attacker to execute arbitrary code. Three stored XSS vulnerabilities (CVE-2026-75684, CVE-2026-75689, CVE-2026-75697) can lead to privilege escalation, while CVE-2026-75686 (insufficient input validation) and CVE-2026-75698 (reflected XSS) can also result in arbitrary code execution. These five require user interaction but no authentication. A separate path traversal flaw, CVE-2026-34689 (CVSS 8.6), allows an unauthenticated attacker to read arbitrary files without any user interaction required.
Adobe states it is not aware of active exploitation of any of these vulnerabilities in the wild. Defenders running Adobe Connect should prioritize patching to version 12.12 and update the Android mobile app to version 4.5. Given the number of critical-rated flaws and the low complexity of exploitation for several (including unauthenticated file read and code execution paths), organizations using Adobe Connect for web conferencing should treat this update as high priority even absent confirmed in-the-wild attacks.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
