Name of the Vulnerable Software and Affected Versions: PHKP including commit 88fd9cfdf14ea4b6ac3e3967feea7bcaabb6f03b

Description: The issue concerns improper neutralization of special elements used in a command, which can lead to command injection. This allows for the manipulation of gpg-keys or the execution of commands remotely. The vulnerable component is the pgp exec() function in phkp.php at line 98. The attack vector is the HKP-Api, specifically the /pks/lookup?search endpoint.

Recommendations: For PHKP including commit 88fd9cfdf14ea4b6ac3e3967feea7bcaabb6f03b, consider disabling the pgp exec() function as a temporary workaround until a patch is available. Restrict access to the /pks/lookup?search endpoint to minimize the risk of exploitation.
