GHSA-6QM2-MCQ7-53QP Duplicate Advisory: jackson-core: Number Length Constraint Bypass in Async Parser Leads to Potential DoS Condition
Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-72hv-8253-57qq. This link is maintained to preserve external references. Original Description The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in...
CVE-2026-18401
The CVE describes a vulnerability in jackson-core’s non-blocking (async) JSON parser where maxNumberLength is not enforced, unlike the synchronous parser. Root cause: the async parsing path in NonBlockingUtf8JsonParserBase does not invoke number length validation; _finishNumberIntegralPart() accu...
