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

Description: The issue is related to an improper neutralization of special elements used in a command, which can lead to command injection. This can result in the manipulation of gpg-keys or the execution of commands remotely. The attack is exploitable via the HKP-Api, specifically the endpoint "/pks/lookup?search".

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