HIGHCVSS 7.6/10EPSS 6.71%

Last modified

CVE-2015-20107 is a high-severity vulnerability rated 7.6/10 on the CVSS scale. In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). EPSS estimates a 6.71% chance of exploitation in the next 30 days.
