Published Apr 14, 2026 · Updated Apr 14, 2026

DOM-based XSS in Adobe Connect 12.10 and earlier and Desktop Application 2025.3 and earlier allows remote attackers to run scripts. The browser processes attacker-manipulated DOM state as executable JavaScript; Adobe has not disclosed the affected page, DOM source, or execution sink. A victim must visit a crafted webpage, after which the script runs in the victim's browser context and can compromise the account or session.
