Emil Lerner and Andrew Danau discovered that insufficient validation in the path handling code of PHP FPM could result in the execution of arbitrary code in some setups.

For the stable distribution (buster), this problem has been fixed in version 7.3.11-1~deb10u1.

We recommend that you upgrade your php7.3 packages.
