CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 1CVE-2021-32707 – Bypass of image blocking in Nextcloud Mail
https://notcve.org/view.php?id=CVE-2021-32707
Nextcloud Mail is a mail app for Nextcloud. In versions prior to 1.9.6, the Nextcloud Mail application does not, by default, render images in emails to not leak the read state. The privacy filter failed to filter images with a `background-image` CSS attribute. Note that the images were still passed through the Nextcloud image proxy, and thus there was no IP leakage. The issue was patched in version 1.9.6 and 1.10.0. • https://github.com/nextcloud/mail/pull/5189 https://github.com/nextcloud/security-advisories/security/advisories/GHSA-xxp4-44xc-8crh https://hackerone.com/reports/1215251 • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
