A use-after-free vulnerability in Apache Fory versions 0.13.0 through 1.3.0 exposes systems to remote attacks and potential memory disclosure.

This flaw is a use-after-free weakness (CWE-416) residing within the Rust deserialization logic. Unauthenticated attackers can trigger this issue by submitting a crafted Fory payload over the network without requiring any user interaction.

A successful exploit against Apache Fory can lead to partial confidentiality, integrity, and availability impacts, resulting in process crashes, potential memory disclosure, or service disruption. With a CVSS score of 7.3, this high-severity vulnerability poses significant operational risks for organizations relying on vulnerable versions for data processing and deserialization tasks.

Immediate Action: Upgrade Apache Fory to version 1.4.0 or later, which contains the official vendor patch for this vulnerability.

Proactive Monitoring: Monitor application error logs and system metrics for unexpected process crashes, service restarts, or abnormal memory consumption patterns indicative of exploitation attempts.

Compensating Controls: Deploy Web Application Filters or input validation routines to inspect and drop malformed deserialization payloads targeting the application interface.

Public Exploit Available: No (false / unknown)

Security teams must treat this high-severity vulnerability with urgency due to its network attack vector and unauthenticated exploitability. Immediate deployment of the patched version 1.4.0 is required to eliminate the risk of memory corruption and unexpected service outages.
