This medium-severity CVE scores 5.9 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 52% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

A security issue was discovered in the LRA Coordinator component of Narayana. When Cancel is called in LRA, an execution time of approximately 2 seconds occurs. If Join is called with the same LRA ID within that timeframe, the application may crash or hang indefinitely, leading to a denial of service.
