CVE-2026-105642
What is CVE-2026-105642?
CVE-2026-105642 is a vulnerability affecting the Ghost content management system (CMS), which is built on Node.js and widely used for creating and managing online content. The vulnerability relates to the handling of Scalable Vector Graphics (SVG) files, specifically within an image processing library embedded in Ghost. Versions 6.56.0 to 6.67.0 are impacted, allowing any staff user, including those with contributor privileges, to create a bookmark card linked to an attacker-controlled website. This could enable the execution of arbitrary commands on the Ghost server. The potential ramifications are significant, as it could facilitate unauthorized operations and compromise the integrity and security of the hosted web applications. The vulnerability has been addressed in version 6.67.0, underscoring the importance of keeping software up to date to mitigate security risks.
