CVE-2022-26526 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Anaconda Anaconda3 (Anaconda Distribution) through 2021.11.0.0 and Miniconda3 through 4.11.0.0 can create a world-writable directory under %PROGRAMDATA% and place that directory into the system PATH environment variable. Thus, for example, local users can gain privileges by placing a Trojan horse file into that directory. EPSS estimates a 0.34% chance of exploitation in the next 30 days.

The person who installs the product must specify that it is being installed for all users. Also, the person who installs the product must specify that the system PATH should be changed.
