CVE-2021-41231 1 Openmage 1 Magento 2026-06-17 N/A 7.2 HIGH
OpenMage LTS is an e-commerce platform. Prior to versions 19.4.22 and 20.0.19, an administrator with the permissions to upload files via DataFlow and to create products was able to execute arbitrary code via the convert profile. Versions 19.4.22 and 20.0.19 contain a patch for this issue.
CVE-2021-41178 1 Nextcloud 1 Server 2026-06-17 4.0 MEDIUM 8.8 HIGH
Nextcloud is an open-source, self-hosted productivity platform. Prior to versions 20.0.13, 21.0.5, and 22.2.0, a file traversal vulnerability makes an attacker able to download arbitrary SVG images from the host system, including user provided files. This could also be leveraged into a XSS/phishing attack, an attacker could upload a malicious SVG file that mimics the Nextcloud login form and send a specially crafted link to victims. The XSS risk here is mitigated due to the fact that Nextcloud employs a strict Content-Security-Policy disallowing execution of arbitrary JavaScript. It is recommended that the Nextcloud Server be upgraded to 20.0.13, 21.0.5 or 22.2.0. There are no known workarounds aside from upgrading.
