First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Atlassian Bitbucket, Atlassian Bitbucket Data Center, Atlassian Bitbucket Server).
Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
Apply the fixed version or the patch documented under Remediation.
EPSS ahead of 100% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
Look for parameters with command/query metacharacters and unexpected child processes of the service.
Hunt retroactively in logs from before Sep 30, 2022 (KEV listing): exploitation may have started earlier.
