Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 78.3%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
Description
The Gravity updater in Pi-hole through 4.4 allows an authenticated adversary to upload arbitrary files. This can be abused for Remote Code Execution by writing to a PHP file in the web directory. (Also, it can be used in conjunction with the sudo rule for the www-data user to escalate privileges to root.) The code error is in gravity_DownloadBlocklistFromUrl in gravity.sh.
