IdentifiersCVE-2025-49552CWE-79· Improper Neutralization of Input…

CVE-2025-49552 is a DOM-based Cross-Site Scripting (XSS) vulnerability affecting Adobe Connect versions 12.9 and earlier. The vulnerability allows a high-privileged attacker to craft a malicious web page that, when visited by a victim, executes arbitrary scripts in the victim's browser context. This can lead to session takeover and compromise of confidentiality and integrity. Exploitation requires user interaction (victim must visit a crafted page).

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation enables an attacker to execute arbitrary JavaScript in the victim's browser, potentially leading to session hijacking, theft of sensitive information, or further attacks within the context of the affected user. The impact is rated high for confidentiality and integrity due to the potential for session takeover.

Mitigation

If you can’t patch tonight, do this now.

Until the update can be applied, restrict access to Adobe Connect to trusted users, monitor for suspicious activity, and educate users to avoid clicking on suspicious or unexpected links.

Remediation

Patch, then assume compromise.

Upgrade Adobe Connect to version 12.10 or later for both Windows and macOS, as these versions address the DOM-based XSS vulnerability.
