CWE-ID: CWE-20 - Improper input validation

CVSSv4: 0 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to inject arbitrary Camel headers.

The vulnerability exists due to improper input validation in Sns2HeaderFilterStrategy when processing inbound SNS message attributes. A remote attacker can send specially crafted message attributes to inject arbitrary Camel headers.

No known exploit path is described because camel-aws2-sns is producer-only and does not map externally supplied SNS message attributes inbound into a Camel Exchange.

Remediation
