CVE-2022-1091 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. The sanitisation step of the Safe SVG WordPress plugin before 1.9.10 can be bypassed by spoofing the content-type in the POST request to upload a file.

EPSS estimates a 1.16% chance of exploitation in the next 30 days.
