CVSS v3.1

Vetor base

AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:N

Name of the Vulnerable Software and Affected Versions Nextcloud Contacts app versions prior to 4.2.4 Nextcloud Contacts app versions prior to 5.0.3

Description The issue concerns the handling of unsanitized SVG files in the Contacts app for Nextcloud. These files are converted into JavaScript blobs, which the Avatar component cannot render. Although the missing sanitization is present, it does not seem to be exploitable due to this specific implementation.

Recommendations For versions prior to 4.2.4, upgrade to version 4.2.4. For versions prior to 5.0.3, upgrade to version 5.0.3.
