0 CVE-2026-91777 is a high-severity vulnerability in FasterXML jackson-databind affecting versions from 2.5.0 through 3.2.2 in specified ranges. It involves uncontrolled resource consumption due to a quadratic CPU workload during deserialization of JSON documents with forward-reference completion for @JsonIdentityInfo object IDs. This occurs when unresolved object-ID references are defined in reverse order, causing excessive identity comparisons. Exploitation requires deserialization of attacker-controlled JSON into identity-enabled collections or maps.
