CVE-2025-68461 is classified as a high-severity Cross-Site Scripting (XSS) vulnerability that affects Roundcube Webmail versions prior to 1.5.12 and 1.6 prior to 1.6.12. This vulnerability allows malicious actors to execute arbitrary JavaScript code in the context of the user’s browser by exploiting the animate tag within an SVG document. The CVSS score for this vulnerability is 7.2, indicating its significant potential impact on affected systems.
The urgency for organizations to address this vulnerability is critical due to the potential for unauthorized access and data theft that could result from successful exploitation. Given that exploit information is available, organizations should prioritize patching immediately to prevent potential attacks.
As this vulnerability is included in the Known Exploited Vulnerabilities (KEV) catalog, its real-world risk is amplified, necessitating immediate attention from security teams to assess and remediate exposure.
Organizations using affected versions of Roundcube Webmail should review their patching schedules and ensure that updates are applied as soon as possible to mitigate the risks associated with this vulnerability.
Vulnerability Details
The official description of CVE-2025-68461 states that Roundcube Webmail versions before 1.5.12 and 1.6 before 1.6.12 are vulnerable to a Cross-Site Scripting (XSS) vulnerability via the animate tag in an SVG document. This vulnerability is classified under CWE-79.
The vulnerability's CVSS 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N, indicating that the attack vector is network-based, the complexity is low, and no privileges or user interaction are required for successful exploitation.
This vulnerability was published on December 18, 2025, and has been analyzed for its impact and exploitability.
Technical Analysis
The root cause of CVE-2025-68461 lies in the improper handling of SVG documents, particularly the animate tag, which can be exploited to inject malicious scripts. The attack vector is network-based, allowing attackers to initiate attacks remotely without physical access to the affected systems.
The attack complexity is low, with no privileges required for exploitation. Additionally, user interaction is not necessary, making this vulnerability particularly dangerous. The confidentiality and integrity impacts are low, but the potential for successful exploitation can lead to significant repercussions for users.
Organizations utilizing Roundcube Webmail should be alert to the risks posed by this vulnerability and implement necessary defenses to mitigate any potential fallout.
