## Technical details

A deserialization of untrusted data vulnerability (CWE-502) exists in JFrog Artifactory's package handling component. The flaw is rooted in the insufficient validation of serialized objects during package processing. A network-based attacker with low-privileged authentication can exploit this by submitting specially crafted payloads under specific repository conditions. Successful exploitation can lead to unauthorized data access, modification of artifacts, or a complete impact on service availability. JFrog has released several patched versions across different release branches to address this issue.
