 # jackson-core async parser maxNumberLength bypass (GHSA-r7wm-3cxj-wff9) - incomplete fix for
 # GHSA-72hv-8253-57qq. Not exploitable: services only use the synchronous ObjectMapper API, not
 # jackson-core's non-blocking/async parser. A jackson bump is also in flight via uid2-shared
 # (PR #631) and will flow on the next release. See: UID2-7557 (predecessor UID2-6670)
