Headline
GHSA-36gq-35j3-p9r9: Excessive Platform Resource Consumption within a Loop when unmarshalling Compose file having recursive loop
Impact
The compose-go library component in versions v2.10-v2.4.0 allows an authorized user who sends malicious YAML payloads to cause the compose-go to consume excessive amount of Memory and CPU cycles while parsing YAML, such as used by Docker Compose from versions v2.27.0 to v2.29.7 included
Patches
compose-go v2.24.1 fixed the issue
Workarounds
There isn’t any known workaround.

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
